The Aim of this Draft Strategy, as stated on the DECLG WebSite, is to ensure that exposure to Radon Gas, which presents a significant public health problem, is addressed in an effective and co-ordinated way across all relevant public authorities through appropriate interventions. The Draft Strategy was developed by an Inter-Agency Group comprising representatives from relevant public authorities.
.
After all of the progress made on radon protection in buildings at the end of the 1990’s and beginning of the 2000’s, it is extremely disappointing to read this miserable excuse for a strategy document. If the general public in Ireland is under any impression that the ‘powers-that-be’ are deeply concerned about protecting our health … they are making a fatal mistake !
The complete absence of any reference to a Recommended Health-Related Radon Target Level – Safety-Related National Reference Levels which are not clearly explained will result in some injury and harm – Lack of Meaningful Consultation with, and Informed Consent of, the National Population – Horrendously Inadequate Technical Control Procedures on Irish Building Sites – RPII Recommended Indoor Radon Activity Measuring Devices having Very High Measurement Uncertainty (±30% under typical conditions of use) – A Purposeful Lack of Detailed Guidance on Exactly When and How to Measure Indoor Radon – Inadequate RPII Radon Measurement Test Reporting … are just some of the tell-tale signs for a seasoned observer.
In this regard, therefore … and let me be very clear and simple in my use of language … this Draft National Radon Control Strategy is a blatant fraud !!
Fraud: Deliberate deception, trickery, or cheating intended to gain an advantage – An act or instance of such deception (from Latin Fraus (f): deceit, deception).
Furthermore … the Inter-Agency Group which produced this Draft National Radon Control Strategy for the DECLG Minister, Mr. Phil Hogan T.D., and Senior Civil Servants within the Department … whoever the Group’s participants are, wherever they are … should be thoroughly ashamed of themselves for being associated with this negligent act !
Negligent: Lacking attention, care or concern.
Negligence: A wrong whereby a person(s) is in breach of a legal duty of care, resulting in harm or injury to another person(s) … in this case, the Irish Public.
To see a complete overview on this Serious Building-Related Human Health Issue, and for information about a Far Better and More Coherent Approach to Radon Protection in Buildings which takes proper account of European Union (E.U.) legislation, e.g. the Precautionary Principle … please refer to SDI’s Corporate WebSite …
SDI’s Comments on Ireland’s Draft National Radon Control Strategy (NRCS)
1.Protecting Human Health versus Reducing Risk to Safety
The following two short extracts from 1. Introduction and Background in the Draft NRCS reveal the true intent of the Inter-Agency Group …
‘ Radon gas is the greatest source of exposure to ionising radiation for the general public and is the second greatest cause of lung cancer in Ireland. Recognising the serious health risk presented by radon, the Minister for the Environment, Community and Local Government in November 2011 established an inter-agency group to develop a National Radon Control Strategy (NRCS).’
and …
‘ During 2012 the inter-agency group developed a draft NRCS based on wide stakeholder consultation and a health economics evaluation of different radon intervention strategies. The stakeholder consultation involved a range of individuals and bodies involved in: health care, construction, radon services, Government and academia. The health economics evaluation was undertaken by the Radiological Protection Institute of Ireland (RPII) and Health Service Executive (HSE) with the assistance of the Health Economics Unit at the University of Oxford. This draft strategy sets out a range of measures to reduce the risk from radon to people living in Ireland.’
Radon is a serious human health issue, and it is explained in a later section of the document 1.2 The Radon Problem in Ireland that ‘indoor radon is linked to between 150 to 200 lung cancer deaths each year in Ireland, which equates to approximately 13% of all lung cancer deaths.’
However … after the references above to ‘health economics evaluation’ (!) … to the ‘prevailing economic situation’ (!!) in section 1.1 Public Consultation … and to ‘health economics tools’ (!!!) in section 2. Draft National Radon Control Strategy … etc … you should then sensitize yourself to the subtle change in language very early in the document … from a consideration of health protection, to reducing the risk from radon (or similar variations on that theme).
The concept of Protecting Human Health is altogether different from the concept of Assessing and Mitigating / Reducing Risk to Safety ! Please refer to SDI’s Corporate WebSite.
As far back as the end of the 1990’s … the Irish Agrément Board, which at the time included a representative from the Department of the Environment, accepted the following …
Radon Activity in Buildings – Recommended Target Health Level
Radon Activity (incl. Rn-222, Rn-220, RnD) should, on average, fall within the range of 10-40 Bq/m3, but should at no time exceed 60 Bq/m3.
This Recommended Target Health Level for Radon now also appears in International Standard ISO 21542: ‘Building Construction – Accessibility & Usability of the Built Environment’, which was published in December 2011. Please refer to Annex B.8 – Indoor Air Quality (IAQ) in the ISO Standard.
The Draft NRCS must refer to such a Recommended Target Health Level … and it must be stated that it is National Policy to progressively reach that target by 2025 (bearing in mind the ‘prevailing economic situation’ in the country !).
Note: In contrast to the above … 200 Bq/m3 for Residential Buildings, and 400 Bq/m3 for Workplaces … are NOT Health-Related Target Levels … they are Safety-Related National Radon Reference Levels which result in some measure of harm and injury to people … particularly children under the age of 10 years, and people with activity limitations who constantly remain indoors for prolonged periods of time.
.
2.National Policy Priority: ‘Real’ Protection from Radon in ‘Real’ Irish Buildings
Yes … in Ireland, we have enormous problems with regard to a lack of awareness among the general population about the serious health hazard posed by indoor radon … and the absence of proper education and training for everyone directly involved in the design, construction, management, operation, servicing or maintenance of our building stock (both new and existing).
BUT … if we are committed to providing ‘real’ radon protection in ‘real’ Irish buildings, then a practical construction-oriented approach is demanded.
This is a Key Paragraph in 2.1 Radon Prevention in New Buildings …
‘ The stakeholder engagement also points to some practical difficulties associated with the implementation of the current technical guidance on radon prevention. These difficulties relate to the correct installation of radon barriers under site conditions, protection of the integrity of radon barriers once installed and identification of radon preventive measures on site. The stakeholder engagement also indicated the system of building control in place prior to 2012 did not provide adequate assurance that radon preventive measures had been correctly installed ‘
… which we later discover is a masterstroke of understatement and evasion, because none of these important issues are tackled head on in the document.
On the critical issue of Building Control … there is no mention of mandatory inspections of construction projects by competent Local Authority personnel. Because … it remains the unwritten policy of Ministers and Senior Civil Servants in Ireland’s Department of the Environment, Community & Local Government (DECLG) that Local Authority Building Control Sections will be entirely ineffective.
On the other hand … will Competent Private Independent Technical Controllers be facilitated in carrying out sufficient inspections of all radon protection related works before ‘signing off’ on proper completion ???
.
3.Regulatory Status of RPII’s Radon Prediction Maps
This is NOT a problem unique to Ireland.
The presence of the RPII Radon Prediction Maps in Technical Guidance Document C (Building Regulations), and the status they are given there … are both entirely inappropriate.
While these Maps are a useful design aid, in the case of small construction projects, they offer NO assurance of certainty to either building designers or users. They are NOT reliable ! And the average values shown in any particular ‘box’ may actually conceal a considerable degree of variability in the radon concentrations found in completed buildings.
.
4.SDI’s Acceptance of RPII Services
Please refer to SDI’s Corporate WebSite.
Unfortunately, until the Radiological Protection Institute of Ireland (RPII) includes proper statements of Measurement Uncertainty in its Test Reports (this is a requirement of European Standard EN ISO/IEC 17025) … our Organization:
cannot recommend any RPII Radon Testing Services to 3rd Parties ;
and
will not accept any RPII Test Reports as proper evidence of Radon Test results.

High Noon for a Festering Planetary Issue … Our Little Planet …
Based on ‘real’ measurements around the world during 2011, the state of Greenhouse Gases (GHG’s) in the Atmosphere is steadily becoming worse … and, following the latest shindig in Doha (UNFCCC – COP 18), the prospect of an effective global agreement on Climate Change Mitigation entering into legal force, anytime soon, is even more remote than ever !
UN WMO Greenhouse Gas Bulletin No.8 – 19 November 2012

World Meteorological Organization’s Greenhouse Gas Bulletin No.8 (2012-11-19), showing … Atmospheric Radiative Forcing, relative to 1750, of Long-Lived Greenhouse Gases (LLGHG’s), and the 2011 Update of the U.S. National Oceanic & Atmospheric Administration’s Annual Greenhouse Gas Index (AGGI). Click to enlarge.
WMO GHG Bulletin No.8 – Executive Summary:
The latest analysis of observations from the WMO Global Atmosphere Watch (GAW) Programme shows that the globally averaged mole fractions of Carbon Dioxide (CO2), Methane (CH4) and Nitrous Oxide (N2O) reached new highs in 2011, with CO2 at 390.9±0.1 parts per million, CH4 at 1813±2 parts per billion, and N2O at 324.2±0.1 parts per billion. These values constitute 140%, 259% and 120% of pre-industrial (before 1750) levels, respectively. The atmospheric increase of CO2 from 2010 to 2011 is similar to the average growth rate over the past 10 years. However, for N2O the increase from 2010 to 2011 is greater than both the one observed from 2009 to 2010 and the average growth rate over the past 10 years. Atmospheric CH4 continued to increase at a similar rate as observed over the last 3 years. The NOAA Annual Greenhouse Gas Index shows that from 1990 to 2011 radiative forcing by Long-Lived Greenhouse Gases (LLGHG’s) increased by 30%, with CO2 accounting for about 80% of this increase.

Climate Change Adaptation
Encompasses urgent and immediate actions at local, national, regional and international levels … to reduce the vulnerability and strengthen the resilience of the Human Environment, including ecological and social systems, institutions and economic sectors … to present and future adverse effects of climate change, including variability and extremes, and the impacts of response measure implementation … in order to minimize the local threats to life, human health, livelihoods, food security, assets, amenities, ecosystems and sustainable development.
Climate Change Adaptation is also the most important driving force for Sustainable Human & Social Development.
.
A few weeks ago, The World Bank(International Bank for Reconstruction and Development, based in Washington D.C.) … an Institution which is not at all shy about dishing out harsh medicine to the Developing World … published a report on Climate Change Adaptation in the Middle East and North Africa/ Arab Region.
What I immediately wondered was … how would we, in the Developed World, like a taste of this same medicine … our own medicine … and would we swallow ?!?
The European Commission has still not produced an E.U. Climate Change Adaptation Strategy or Plan.
In Ireland … our National Climate Change Strategy (2007-2012) has just lapsed, with no replacement in sight … and, confirming a lack of both political leadership and institutional capacity … any mention of the word ‘Adaptation’ creates either panic or apathy … depending on the individual, and his/her responsibilities.
.
So … as appropriate, just substitute your own country wherever there is a reference to ‘Arab Region’ or ‘Arab Countries’ in the text below … and see how you feel …
World Bank (IBRD) Report 73482 – 1 December 2012
Adaptation to a Changing Climate in Arab Countries – A Case for Adaptation Governance & Leadership in Building Climate Resilience
.
Selected Extracts from World Bank MENA Report’s OVERVIEW:
Climate change is happening now in the Arab Countries. The year 2010 was the warmest since the late 1800’s, when this data began to be collected, with 19 countries setting new national temperature highs. Five of these were Arab Countries, including Kuwait, which set a record high of 52.6 °C in 2010, only to be followed by 53.5 °C in 2011. Extreme climate events are widely reported in local media, and a 2009 Arab Region Survey showed that over 90% of the people sampled agree that climate change is occurring and is largely due to human activities; 84% believe it is a serious challenge for their countries; and respondents were evenly split on whether their governments were acting appropriately to address climate change issues. The sample came mostly from the better-educated population, but it shows that there is a firm base and desire for action regarding climate change across the Arab Region.

Arab Countries can take action to reduce their vulnerability to climate change. For example, this report proposes an Adaptation Pyramid Framework that assists stakeholders in Arab Countries in integrating climate risks and opportunities into development activities. It is based on an adaptive management approach, but it also highlights the importance of leadership, without which adaptation efforts are unlikely to achieve the necessary commitment to be successful. The Framework begins by assessing climate risks and opportunities and identifying options within the context of other development planning. The next step is to identify and prioritize adaptation options within the context of national, regional, and local priorities. Finally, adaptation responses will be implemented and outcomes monitored over time. It is important to take into account the long-term consequences of these decisions, because short-term responses may not be efficient or could lead to maladaptive outcomes. Other important measures for Arab Region policy makers to implement are discussed below …

Facilitate the development of publicly accessible and reliable information related to climate change. Access to quality weather and climate data is essential for policy-making. Without reliable data on temperature and precipitation levels, it is difficult to assess the current climate and make reliable weather forecasts and climate predictions. For example, information on river flows, groundwater levels, and water quality and salinity is critical for assessing current and future water availability. However, climate stations across most of the Arab Region are very limited compared to most other parts of the world and what data exists is often not digitized or publicly available. Conflict in parts of the region disrupts both the collection and sharing of data. Information on food production and the main food supply chains (such as changes in agricultural yields and production for important crops, forage, and livestock) needs to be linked with weather and water data to better monitor and understand the effects of a changing climate. In addition, socio-economic data (including household and census data) and other economic data related to the labour market and production should be collected and made available.
Build climate resilience through social protection and other measures. Resilience is determined by factors such as an individual’s age, gender, and health status, or a household’s asset base and degree of integration with the market economy. Underinvestment in social safety nets – public services such as water supply and wastewater treatment, and housing and infrastructure – make people more vulnerable to a changing climate. Further, there should be measures in place to ensure equitable access to health care and a quality education. Such social protection measures include insurance schemes, pensions, access to credit, cash transfer programs, relocation programs, and other forms of social assistance. These investments and instruments facilitate economic and social inclusion, which creates co-benefits between adaptation and development goals.
Develop a supportive policy and institutional framework for adaptation. Basic conditions for effective development, such as the rule of law, transparency and accountability, participatory decision-making structures, and reliable public service delivery that meets international quality standards are conducive to effective development and adaptation action. In addition, climate change adaptation requires new or revised climate-smart policies and structures at all levels.
Sound adaptation planning, strong governmental/non-governmental co-operation, and plentiful financial resources are all important for building resilience to climate change. Developing national adaptation strategies are important for prioritizing adaptation activities that respond to urgent and immediate needs, and for setting forth guiding principals in the effort to cope with climate change. National governments have a key role in developing these strategies and as a result play an important role in promoting collaboration and co-operation. This co-operation should include the government, civil society, the private sector, and international institutions. Within governments, inter-ministerial co-ordination is especially critical, because adaptation responses often require activities involving multiple ministries and sectors. Finally, to do any of the activities above it is important to secure the necessary financial resources. There are many sources for adaptation funding, but first the Arab Countries will need to build their capacity to analyze their financial needs and generate and manage these resources.
By nature, adaptation to climate change is a dynamic process, and so is the governance of adaptation. Political change, including those changes originating from the Arab Spring, can provide an opportunity to increase civil society participation in adaptation governance and a move toward a more inclusive approach to addressing climate change issues and building climate resilience.
This report is about climate change, its impacts on people, the systems upon which we depend, and how we might adapt to climate change. It highlights a number of issues and areas that are being affected by climate change. One important message of this report is that climate change should be taken into account in all activities – however, this report cannot provide solutions or options for all issues. For example, the transboundary water issues are already being addressed by international task forces; this report can deal only with how climate change might affect their decisions. Anticipation of climate change can be the stimulus for improving interventions and accelerating action, which has been seen in countries such as Australia, where water laws and management were extensively changed in response to a prolonged drought and the anticipation of further climate change issues.
2012-11-30: Related specifically to my 2 Previous Posts on 27 November 2012 & 28 November 2012 … this is how we would like to help you … whether you are an individual, or an organization … whether you are located in Ireland, Italy or Turkey … some other part of Europe, the Arab Gulf Region, India, Japan, China … or wherever !

Introduction
For many Weak and Vulnerable People, today’s Complex Human Environment is inaccessible and unsafe … a hostile ‘reality’ which prevents independent functioning and participation in a local community; it is a blatant denial of their human rights.
Restrictions on Social Participation, e.g. physical barriers, sloppy user-unfriendly management procedures, discrimination, stigma, etc … also limit the Use Potential of buildings, transportation systems, public spaces and other facilities … shortening product life cycles.
These factors impose a large, negative cost burden on society generally … and on you, as an individual … or as an organization, whether private or public. It is bad business !

2012-11-28: On Monday last, 26 November 2012 … Fire broke out at a Sheltered Workshop for People with Activity Limitations, located in the small municipality of Titisee-Neustadt, south-western Germany … not too far from the borders of France and Switzerland. It was approximately 14.00 hrs in the afternoon … in broad daylight.
German news reports put the death toll at 14 People, including 1 Carer … with 10 People injured.
News reports also state that it took 2 Hours for Firefighters to bring this incident under control. At the time that Photograph 1, below, was taken … smoke had spread throughout a major part of the building.
Viewers should look closely at the top of the external staircase … then, ask yourselves how any person with an activity limitation can be safely rescued, or assisted to evacuate, by means of a ladder (obscured, at the end of the building on the left) … and, finally, notice the positioning of fire hoses on the ground and on the staircase … some of the many issues which have been discussed extensively here before …

2005 NIST(USA) Final Report on 9-11 World Trade Center 1 & 2 Tower Collapses
– Recommendation #17b –
To the degree possible, people with activity limitations should be provided with a means for self-evacuation in the event of a building emergency. Current strategies (and law) generally require these people to shelter-in-place and await assistance. New procedures, which provide redundancy in the event that the fire warden system or co-worker assistance (e.g. the buddy system) fail, should consider full building evacuation, and may include use of fire-protected and structurally hardened elevators, motorized evacuation technology, and dedicated communication technologies.
.
At the heart of the impressive show of fire fighting equipment and technology … and the usual reassuring statements by local officials and other people in authority after the event … there is an equally impressive lie …

Current Building Codes and Regulations, Fire Safety Standards, Building Design Practices, and Building Management Procedures … do not seriously consider the safety of People with Activity Limitations … not properly – not adequately – not even INadequately. Tokenism is the best offer available in just a few European countries.

According to Spiegel OnLine International …
The rescue was difficult because some people panicked, said Local Fire Chief Alexander Widmaier. “We are dealing here with people who naturally do not respond rationally”, he said.
IF this is an accurate news report, and bearing in mind that it is also a translation … I SAY …
Let us be generous and kind … Local Fire Chief Alexander Widmaier has NO awareness or understanding of People with Activity Limitations and the daily challenges they face in moving around and using a built environment which is inaccessible and unsafe.
According to AFP OnLine …
Gotthard Benitz, of the Titisee-Neustadt fire service, told AFP earlier that the fire began on the ground floor of the building which also had a basement and an upper floor.
“The victims were all on the same floor where the fire was”, he said adding this was the only area to have sustained fire damage and the stairwell had remained smoke-free meaning those on the other two floors had been able to use it.
He also said firefighters were prepared for dealing with an emergency at the workshop as practice fire alarms were regularly carried out there, with the last one having been last year.
The head of Caritas in Germany, Peter Neher, told ZDF public television that emergency practice drills were done regularly.
IF this is an accurate news report, and bearing in mind that it is also a translation … I SAY …
Gotthard Benitz should also look at the top of the external staircase in Photograph 1 above. IF there are no circulation hazards, e.g. ice, or obstacles, e.g. fire hoses … able-bodied people can easily go up or down a staircase … people who use wheelchairs or other mobility-aid devices cannot.
In their respective positions of responsibility … Gotthard Benitz and Peter Neher should both understand that all building occupants must be facilitated in acquiring the skill of evacuation to a ‘place of safety’, by way of a safe and accessible route. An emergency practice drill, although carried out regularly once a year … is ENTIRELY inadequate … and will achieve Very Little.
Skill: The ability of a person – resulting from training and regular practice – to carry out complex, well-organized patterns of behaviour efficiently and adaptively, in order to achieve some end or goal.
Standard fire evacuation training and practice drill procedures must be adapted to the individual-specific abilities of People with Activity Limitations.
.
BUT … the new International Standard ISO 21542 is a very small step in the right direction. See yesterday’s post.
This situation will only improve to a significant degree, however, when People with Activity Limitations, and their Representative Organizations, begin to act decisively, in unison, and with serious intent …

Self-Protection from Fire in Buildings – Personal Check List for People with Activity Limitations
1. Upgrade ‘My’ understanding of Accessibility …
Ease of independent approach, entry, egress, evacuation and/or use of a building and its services and facilities, by all of the building’s potential users – with an assurance of individual Health, Safety and Welfare during the course of those activities ;
2. Be assertive (not aggressive) with regard to ‘My’ own self-protection in emergency situations ;
3. Concerning ‘My’ safety … demand that Building Management actively engages in Meaningful Consultation – and receives your Informed Consent ;
4. Become familiar with the Fire Defence Plan for the building, and know ‘My’ part well ;
5. Practice – practice – practice … become skilled in evacuation to a Place of Safety ;
6. Become involved, and participate directly in the Building’s Safety Procedures.

Self-Protection from Fire in Buildings – Must-Do List for Representative Organizations & Groups
1. Upgrade ‘Our’ understanding of Accessibility in a Social Context, its Current Vocabulary, and its Complexity … groups of individuals wish to socialize together … this is now, afterall, a recognised human and social right !
Ease of independent approach, entry, egress, evacuation and/or use of a building and its services and facilities, by all of the building’s potential users – with an assurance of individual Health, Safety and Welfare, and group Wellbeing, during the course of those activities ;
2. Be assertive (and aggressive) with regard to the availability of proper Data and Statistics – we must clearly identify ‘Our’ problem with the many restrictions placed on our participation in local communities ;
3. Produce a working statement of an Individual’s Rights – on 1 Page (!) ;
4. Issue clear guidelines on Reliable Advocacy ;
5. Become involved, and participate directly in the improvement of Building Codes and Regulations, Fire Safety Standards, Building Design Practices, and Building Management Procedures ;
6. Demand resources to Monitor ‘Effective’ Implementation … and Target Relevant and ‘Practical’ Research.
2012-11-27: On Friday last, 23 November 2012, I had the great pleasure of being invited to attend the 2012 IIEA/TEPSA Irish EU Presidency Conference, which was held in Dublin Castle, Ireland. The Programme was interesting and diverse … but lacked a vital element …

Session 2 – Economic Governance & Economic Monetary Union ;
Session 3 – Innovation & the Digital/Energy Interface ;
Session 4 – The European Union in the World.

Although the serious problem of Youth Unemployment in Europe was discussed (from an economic perspective), and the Ageing Society received a passing mention … there was hardly any consideration of EU Citizenship and the many other Soft Social Issues … with, surprise-surprise, no reference at all to the Weak and Vulnerable Groups of People in all of our countries.
Furthermore … I don’t know whether they were invited to the Dublin EU Presidency Conference … and if they were, whether they couldn’t attend … but I did not notice a significant presence of representatives from Irish Disability Organizations at this important event.
Conference Delegates needed to hear that the European Union is for All of its People … not just its Citizens ! That distinction is critical.

Which sets the scene, in an odd way, for the following e-mail message I recently sent through the EUropean Concept for Accessibility Network (EuCAN) … a network of European Accessibility Experts, co-ordinated from Luxembourg by Mr. Silvio Sagramola …
.
To EuCAN Network Members:
Silvio,
With some concern, I have been following the discussion about Access Officers.
Allow me to explain.
Once upon a time … at a meeting of the EuCAN Management Team in Luxembourg … there was an intense discussion about ‘Accessibility & Human Rights’. Now that the U.N. Convention on the Rights of Persons with Disabilities has been adopted, entered into force, and been ratified by the European Union and many, though not all, of the EU Member States … I hope that this issue has finally been resolved.
Therefore … the immediate, Pan-European Accessibility Agenda can be found in Articles 9, 11 and 19 of the Convention … all within the context of Preamble Paragraph (g).
BUT … is any organization yet working with this Agenda … and, most importantly, implementing it properly ?
AND … let us not forget that Independent Mechanisms to Monitor Implementation are an essential component of the same Agenda (Article 33.2) … at European, national, and sub-national levels, right down to individual public and private organizations !
.
Accessibility has been clearly specified in the new International Standard ISO 21542: ‘Building Construction – Accessibility & Usability of the Built Environment’ as including … ‘access to buildings, circulation within buildings and their use, egress from buildings in the normal course of events, and evacuation in the event of an emergency‘.
The flawed framework, founded on the term ‘Access’ alone, is now obsolete. And, therefore, the Access Officer is no more. Let us all finally agree that the responsible individual, whether he or she, is an Accessibility Officer !
.
If the EuCAN Network is to have a useful and constructive future, this is the New Legal & Normative Environment which it must confront, carefully examine … and, in support of which, it should produce design guidance, decision-making computer software tools, etc., etc … for the practical purpose of ‘real’ implementation.
AND … any proposed EuCAN Programme of Action (2013-2015) should also include a review and updating of past publications.
.
Some Points To Note:
1. Although the European Union ratified the U.N. CRPD on 23 December 2010 … European Commissioner Viviane Reding (Justice, Fundamental Rights & Citizenship) stated at a Dublin Meeting, in answer to my direct question, that some Member States are offering stiff resistance to integration of the Convention into the EU System. Why isn’t the European Disability Forum on top of this ? But also … the European Union has not yet either signed, or ratified, the Convention’s Optional Protocol.
2. At the time of writing … Finland, Ireland, the Netherlands, and Norway (EEA) … have still not ratified the Convention. Why not ? Where is the outcry from disability organizations in those countries ??
In Ireland, unfortunately, national decision-makers would rather commit ritual suicide outside government buildings than acknowledge an individual citizen’s human rights. And, if Ireland ever does ratify the Convention, proper implementation will be very problematic.
Am I exaggerating ? Not at all … just look at how Ireland has implemented the U.N. Convention on the Rights of the Child, which it ratified back in September 1992.
3. In EU Member States that have ratified the U.N. CRPD … the Convention is not always being implemented properly.
4.Preamble Paragraph (g) of the U.N. CRPD is even more important, now, for this reason … the United Nations has started to develop the Post-2015 Sustainable Development Goals. It is essential to fully integrate Ability/Disability Issues into this process. Making a submission to the U.N. could be an interesting task for EuCAN.
5.The Fire Safety Texts contained in ISO 21542 are essentially just a bare minimum … and they are mostly in the form of recommendations (‘should’), not requirements (‘shall’). There is a great need to add extra detail to those texts … and to convert them into requirements. Making a series of submissions to the International Standards Organization (ISO) should be a task for EuCAN.
EUropean Concept for Accessibility (EuCAN) – Extract from 2001 Mission Statement
The fundamental basis of a European philosophy for accessibility is the recognition, acceptance and fostering – at all levels in society – of the rights of all human beings, including people with activity limitations … in an ensured context of high human health, safety, comfort and environmental protection. Accessibility for All is an essential attribute of a ‘person-centred’, sustainable built environment.
An Effectively Accessible Europe for All
Now that a Comprehensive Legal and Normative Environment for Accessibility has finally been created in Europe … there is a vital need for EuCAN for serve … and a vital role for EuCAN to play.
However … Concerted Action must be directed at Implementation … Effective Implementation … ‘real’ accessibility which works.
2012-10-25: The Practice Philosophy of Sustainable Design International Ltd. is an issue which has occupied my mind greatly during this past summer … as I asked myself some difficult questions …
What has really been happening to our planet since 1992 … and earlier, since 1972 ?
Where is SDI now ?
Are we on the same track … the right track ?
Where are we going in the short to medium-term future ?
Architecture … is practice as a separate design disciple now obsolete ?
Fire Engineering … can it be dragged, screaming, from the proverbial ‘caves’ … and transformed to respond creatively to the safety and security requirements of a complex built environment ?
Sustainability … what impact does this intricate, open, dynamic and still evolving concept have … should it have … on the provision of conventional Architectural and Fire Engineering Services ?
‘Green’ … is this marketing ploy helpful … or an annoying obstacle … to effective implementation of Sustainable Development ?

This publication serves as a timely update on what has occurred since the Earth Summit of 1992 and is part of the wider Global Environment Outlook-5 (GEO-5) preparations that will lead to the release of the landmark GEO-5 report in May 2012. It underlines how in just twenty years, the world has changed more than most of us could ever have imagined – geopolitically, economically, socially and environmentally. Very few individuals outside academic and research communities envisaged the rapid pace of change or foresaw developments such as the phenomenal growth in information and communication technologies, ever-accelerating globalization, private sector investments across the world, and the rapid economic rise of a number of ‘developing’ countries. Many rapid changes have also taken place in our environment, from the accumulating evidence of climate change and its very visible impacts on our planet, to biodiversity loss and species extinctions, further degradation of land surfaces and the deteriorating quality of oceans. Certainly, there have been some improvements in the environmental realm, such as the significant reduction in ozone-depleting chemicals and the emergence of renewable energy sources, new investments into which totalled more than $200 thousand million in 2010. But in too many areas, the environmental dials continue to head into the red.

‘Foreword’ …
If we measured the world’s response to environmental challenges solely by the number of treaties and agreements that have been adopted, then the situation looks impressive. Over 500 international environmental agreements have been concluded since 1972, the year of the Stockholm Conference and the establishment of the United Nations Environment Programme (UNEP).
These include landmark conventions on issues such as trade in endangered species, hazardous wastes, climate change, biological diversity and desertification. Collectively, these reflect an extraordinary effort to install the policies, aims and desires of countries worldwide to achieve sustainable development.
Yet despite the impressive number of legal texts and many good intentions, real progress in solving the environmental challenges themselves has been much less comprehensive, a point clearly underlined in the Global Environment Outlook-5 (GEO-5), for which this report ‘Measuring Progress: Environmental Goals and Gaps’ and a previous publication ‘Keeping Track of Our Changing Environment: From Rio to Rio+20’ are companion products leading up to Rio+20.
This report outlines findings from a UNEP study that, with support from the Government of Switzerland, has catalogued and analyzed existing ‘Global Environmental Goals’ contained in the international agreements and conventions. It asks the fundamental question as to why the aims and goals of these policy instruments have often fallen far short of their original ambition and intentions. One possible reason is that many of the goals are simply not specific enough; the few goals that are specific and measurable appear to have a much better record of success.
These include goals to phase out lead in gasoline, ozone-depleting substances (ODS) and certain persistent organic pollutants (POP’s), specific Millennium Development Goal targets calling to halve the number of people without access to safe drinking water and improved sanitation, and targets to increase the number and extent of protected areas. Indeed, even when measurable targets have been set but not actually met, they have usually led to positive change and often to significant change.
The vast majority of goals, however, are found to be ‘aspirational’ in nature. They lack specific targets, which generate obvious difficulties in measuring progress towards them. In addition, many aspirational goals are not supported by adequate data that can be used to measure progress, global freshwater quality being one stark example.
It is clear that if agreements and conventions are to achieve their intended purpose, the international community needs to consider specific and measurable goals when designing such treaties, while organizing the required data gathering and putting in place proper tracking systems from the outset.
A set of Sustainable Development Goals, as proposed by the UN Secretary-General’s High-Level Panel on Sustainability, could be an excellent opportunity and starting point to improve this situation while representing another positive outcome from Rio+20, two decades after the Rio Earth Summit of 1992 and four decades after the Stockholm Conference.

2012-06-05: Continuing on from the last post … the European Environment Agency (EEA), in Copenhagen, recently published EEA Technical Report 2/2012: ‘The Impacts of Endocrine Disrupters on Wildlife, People and Their Environments – The Weybridge+15 (1996–2011) Report’. In this case, hitting the internet search engines might be time very well spent …
What are we doing to ourselves in the Built Environment ? And … do we know how badly we are contaminating the Natural Environment ??
Building Related Ill-Health: Any adverse impact on the health of building users – while living, working, generally occupying or visiting a specific building – caused by the planning, design, construction, management, operation or maintenance of that building.
Endocrine Gland (human): A gland which secretes a substance (a hormone) directly into the bloodstream. The endocrine glands are ‘glands of internal secretion’. They include the hypothalamus, pituitary gland, pineal gland, thyroid, parathyroid glands, heart (which makes atrial-natriuretic peptide), the stomach and intestines, islets of Langerhans in the pancreas, the adrenal glands, the kidney (which makes renin, erythropoietin, and calcitriol), fat cells (which make leptin), the testes, the ovarian follicle (estrogens) and the corpus luteum in the ovary.
.
EEA Technical Report 2/2012 – General Introduction …
1.1 Endocrine Disruption and the European Union (EU)
Genital malformations in baby boys have been increasing in many European countries, and the number of people diagnosed with breast, testis and prostate cancers continues to rise. Recent data indicate that in parts of Europe, sperm quality is approaching crisis levels that may impair fertility. At the same time, there is a secular trend towards earlier onset of puberty in young girls, and a steep increase in the paediatric rates of endocrine nutritional and metabolic disorders such as type II diabetes and obesity. Thyroid cancer rates have increased by between 5.3% (Switzerland) and 155.6% (France), particularly in females, children and young adults. Similarly, congenital hypothyroidism and neurodevelopmental disorders such as autism and attention deficit disorder are much more prevalent than they were 20 years ago.
The trends in the incidences of these endocrine diseases have changed in a manner concomitant with the rapid expansion in growth of the chemical industry, leading to growing speculation that these factors may be linked. There is also compelling evidence of compromised development, growth and reproduction in a number of wildlife species, with reports of alterations and abnormalities in sexual development, impaired thyroid function, and thyroid abnormalities, particularly in environments contaminated by cocktails of chemicals in everyday use.
The concern is that chemicals able to interfere with the normal functioning of hormones, i.e. EDC’s, may play a role in these conditions. Such chemicals can be found in food, household products and cosmetics. The apparent parallels between effects reported in humans and wildlife populations are not surprising, given the overlap between their environments and their food chains.
To investigate the potential harmful effects of EDC’s, the EU has embarked on extensive research efforts and to date has launched scientific projects worth more than €150 million. The intention has been to provide the EU with the information it needs to ensure the safety of chemicals in use and to be used in the future. A lot of this research has now been completed and new findings concerning the effects of chemicals, especially when present as cocktails, have emerged. Progress has also been made in pinpointing human life stages particularly vulnerable to ED, and new data about endocrine health in both humans and wildlife have come to light.
2012-05-31 (2021-08-02): The Revised International Standard ISO 21542: ‘Building Construction – Accessibility & Usability of the Built Environment’ was published on 1 June 2021. Many years before, however, a decision was taken to link this Standard directly to the United Nations Convention on the Rights of Persons with Disabilities (#CRPD) … specifically now referencing Preamble Paragraph (g) and Articles 9, 10, 11, 12 and 19 in its Introduction. Reading the document, this linkage looks and feels very naturally like an unbreakable umbilical cord !

.
ISO 21542 has significantly widened the meaning of the concept #Accessibility4ALL … a normal evolutionary process … in particular, the #FireSafety4ALL Texts. I wonder, though, how many people would ever have considered Good Indoor Air Quality to be on the ‘Accessibility’ Menu ??
.

.
Much lower rates of direct fresh air ventilation … and a dramatic reduction in accidental or unintended air seepage from, or into, buildings (depending on local climate conditions) … all driven by an urgent need to conserve energy and to impose greater energy efficiencies on the energy which is actually consumed … are, once again, one of the main causes of serious health problems for ALL #BuildingUsers …
Building Related Ill-Health: Any adverse impact on the health of building users – while living, working, generally occupying or visiting a specific building – caused by the planning, design, construction, management, operation or maintenance of that building.
I say “once again” because, in Europe, we have been here before … after the two big oil crises of the 1970’s.
.
Anyway … I thought that it would be useful to present a relevant extract from ISO 21542 …
B.8 – INDOOR AIR QUALITY (#IAQ)
Poor indoor air quality, an important factor in relation to Building Related Ill-Health (also known as ‘sick building syndrome’), can cause serious health impairments and severely restrict a person’s participation in everyday activities, e.g. work.
Symptoms and signs may include:
irritation of eyes, nose and throat ;
respiratory infections and cough ;
voice hoarseness and wheezing ;
asthma ;
dry mucous membrane and skin ;
erythema (reddening or inflammation of the skin) ;
lethargy ;
mental fatigue and poor concentration ;
headache ;
stress ;
hypersensitivity reactions, i.e. allergies ;
nausea and dizziness ;
cancers.
These symptoms and signs are present in the population at large, but are distinguished by being more prevalent in some building users, as a group, when compared with others. The symptoms and signs may disappear, or may be reduced in intensity, when an affected person leaves the building. It is not necessary that everyone in a building should be affected before building related ill-health is suspected.
ISO 16814: ‘Building Environment Design – Indoor Air Quality – Methods of Expressing the Quality of Indoor Air for Human Occupancy’ covers methods of expressing indoor air quality (IAQ) and incorporating the goal of achieving good IAQ into the building design process. It also covers ventilation effectiveness, harmful emissions from building materials, air cleaning devices, and heating, ventilation and air conditioning equipment.
The indoor pollutants considered in ISO 16814 include human bio-effluents, which have often been the principal consideration in air quality and ventilation design, but also the groups and sources of pollutants which can reasonably be anticipated to occur in the building during its long Life Cycle.
These pollutants, depending on the sources present, may include:
volatile organic compounds (#VOC’s) and other organics, such as formaldehyde ;
environmental tobacco smoke (#ETS) ;
natural radon, consisting of a number of different isotopes, is an invisible radioactive gas, and is found in the soils under buildings, water supplies to buildings and in the air ;
other inorganic gases, such as carbon monoxide (#CO), the oxides of nitrogen (NOx), and low-level ozone (smog) which is formed when NOx and VOC’s react in the presence of sunlight ;
viable particles, including viruses, bacteria and fungal spores ;
non-viable biological pollutants, such as particles of mites or fungi and their metabolic products ;
non-viable particles, such as dusts and fibres.
The following Two Performance Indicators of Good Indoor Air Quality, developed with the aim of protecting human health, are recommended:
Radon Activity (including Rn-222, Rn-220, RnD) in a building should, on average, fall within the range of 10-40 Bq/m3, but should at no time exceed 60 Bq/m3.
Carbon Dioxide (CO2) concentrations in a building should not significantly exceed average external levels – typically within the range of 300-500 parts per million (#PPM) – and should at no time exceed 800 ppm.
[ While the current CoVID-19 Pandemic lasts … these are Essential ‘Health’ Performance Indicators, as opposed to ‘Safety’ Indicators … and they should be stringently operated and constantly monitored in all building types. ]
” In the early hours of the morning of Saturday, 14th February 1981, a disastrous fire swept through a building called the Stardust in the North Dublin suburb of Artane during the course of a St. Valentine’s Night ‘disco’ dance. Forty eight people were killed and one hundred and twenty eight seriously injured. The overwhelming majority of the victims were young people. “
‘Introduction’, Report of the Tribunal of Inquiry on the Fire at the Stardust, Artane, Dublin, on the 14th February 1981. Report dated 30 June 1982.
As a young architect in private practice … I witnessed, at first hand, the Dublin Fire ‘Establishment’ disappear from public view, without trace, after the Stardust Fire Tragedy. It was almost impossible, for at least a year afterwards, to have a meeting with any Fire Prevention Officer in the Dublin Fire Authority. This was a very valuable lesson.
Later, following the publication of the Stardust Tribunal Report … were its Recommendations implemented … with urgency … and conscientiously ? No way. For example, it was more than ten years after the Stardust Fire before an inadequate system of legal National Building Regulations was introduced in Ireland. And to this day, the system of AHJ monitoring of construction quality, throughout the country, is weak and ineffective … lacking both competent personnel and resources !
The proof of the pudding is in the eating … and one of the results, also in Dublin, has been last year’s debacle at the Priory Hall Apartment Complex … where all of the residents had to leave their expensive apartments for fire safety (and many other) reasons. The tip of a very large iceberg. See my post, dated 18 October 2011 .
And this is where the problems usually begin …
” There has been a tendency among students of architecture and engineering to regard fire safety as simply a question of knowing what is required in terms of compliance with the regulations. The recommendation of the Tribunal of Enquiry into the Summerland Disaster that those responsible for the design of buildings should treat fire safety as an integral part of the design concept itself, has not yet been reflected in the approach to the subject at university level. There is still clearly a need for a new approach to the structuring of such courses which will in time bring to an end the attitude of mind, too prevalent at the moment, that compliance with fire safety requirements is something that can be dealt with outside the context of the overall design of the building. “
‘Chapter 9 – Conclusions & Recommendations’, Report of the Tribunal of Inquiry on the Fire at the Stardust, Artane, Dublin, on the 14th February 1981. Report dated 30 June 1982.
This Recommendation has still not been implemented … and note the reference to the earlier fire at the Summerland Leisure Centre in 1973, on the Isle of Man, when 50 people were killed and 80 seriously injured.
Today … the same attitude of mind, described so well above, stubbornly persists in all sectors, and in all disciplines, of the International Construction Industry … even within ISO Technical Committee 92: ‘Fire Safety’ !
.
Which brings me, neatly, to the recent question posed by Mr. Glenn Horton on the Society of Fire Protection Engineers (SFPE-USA) Page of LinkedIn ( http://www.linkedin.com/groups?gid=96627 ). As usual, the shortest questions can prove to be the most difficult to answer …
” Can you expand on, or point to where anyone has discussed, the ‘very flawed design approach’ please ? “
.
ESSENTIAL PRELIMINARIES …
1. Foundation Documents
I am assuming that ‘people-who-need-to know’, at international level, are familiar with the Recommendations contained in these 2 Reports …
NIST (National Institute of Standards and Technology). September 2005. Federal Building and Fire Safety Investigation of the World Trade Center Disaster: Final Report on the Collapse of the World Trade Center Towers.NIST NCSTAR 1Gaithersburg, MD, USA ;
and
NIST (National Institute of Standards and Technology). August 2008. Federal Building and Fire Safety Investigation of the World Trade Center Disaster: Final Report on the Collapse of World Trade Center Building 7.NIST NCSTAR 1A Gaithersburg, MD, USA ;
… and the contents of the CIB W14 Research WG IV Reflection Document … which, together with its 2 Appendices, can be downloaded from this webpage … https://www.cjwalsh.ie/progressive-collapse-fire/ … under the section headed: ‘April 2012’.
However … I am utterly dismayed by the number of ‘people-who-need-to know’ … who do not know … and have never even bothered to dip into the 2 NIST Reports … or the many long-term Post 9-11 Health Studies on Survivors which have already revealed much priceless ‘real’ information about the short and medium term adverse impacts on human health caused by fire !
CIB W14 Research Working Group IV would again strongly caution that Fire-Induced Progressive Damage and Disproportionate Damage are fundamental concepts to be applied in the structural design of all building types.
.
2. Technical Terminology
While attending the ISO TC92 Meetings in Thessaloniki, during the last week of April 2012, I noticed not just one reference to ‘fire doors’ in a Draft ISO Fire Standard … but many. It surprised me, since I thought this issue had been successfully resolved, at ISO level, many years ago. There is no such thing as a ‘fire door’ … and the careless referencing of such an object, which has no meaning, in building codes and standards has caused countless problems on real construction sites during the last 20-30 years.
Please follow this line of thought …
Fire Resistance: The inherent capability of a building assembly, or an element of construction, to resist the passage of heat, smoke and flame for a specified time during a fire.
Doorset: A building component consisting of a fixed part (the door frame), one or more movable parts (the door leaves), and their hardware, the function of which is to allow, or to prevent, access and egress.
[Commentary: A doorset may also include a door saddle / sill / threshold.]
Fire Resisting Doorset / Shutter Assembly: A doorset / shutter assembly, properly installed or mounted on site, the function of which is to resist the passage of heat, smoke and flame for a specified time during a fire.
… and so we arrive at the correct term … Fire Resisting Doorset … which, as an added bonus, also alerts building designers, construction organizations, and even AHJ inspectors, to the fact that there is more involved here than merely a door leaf.
Now then, I wonder … how, in any sane and rational world, can the term Fire Resistance be used in relation to structural performance during a fire, and the cooling-phase afterwards ? Yet, this is exactly what I read in the building codes of many different jurisdictions. Do people understand what is actually going on ? Or, is the language of Conventional Fire Engineering so illogical and opaque that it is nearly impossible to understand ?
And … if this problem exists within the International Fire Science & Engineering Community … how is it possible to communicate effectively with other design disciplines at any stage during real construction projects. The artificial environments found in academia are not my immediate concern.
.
3. Fire Research & Development outside CIB W14 & ISO TC92
In 2012 … there is something very wrong when you have to struggle to persuade a group of people who are developing an ISO Standard on Design Fire Scenarios … that they must consider Environmental Impact as one of the major consequences of a fire to be minimized … along with ‘property losses’ and ‘occupant impact’. This is no longer an option.
Environmental Impact: Any effect caused by a given activity on the environment, including human health, safety and welfare, flora, fauna, soil, air, water, and especially representative samples of natural ecosystems, climate, landscape and historical monuments or other physical structures, or the interactions among these factors; it also includes effects on accessibility, cultural heritage or socio-economic conditions resulting from alterations to those factors.
So … how timely, and relevant to practitioners, are ISO Fire Standards ? Perhaps … obsolete at publication … and not very ??
And … there is lot more to the Built Environment than buildings …
Built Environment: Anywhere there is, or has been, a man-made or wrought (worked) intervention in the natural environment, e.g. cities, towns, villages, rural settlements, service utilities, transport systems, roads, bridges, tunnels, and cultivated lands, lakes, rivers, coasts, and seas, etc … including the virtual environment.
.
We should be very conscious that valuable fire-related research takes place outside, and unrelated to, the established fire engineering groupings of CIB W14 & ISO TC92. But I am curious as to why this research is not properly acknowledged by, or encouraged and fostered within, the ‘system’ ?
Example A: Responding to Recommendation 18 in the 2005 NIST WTC Report … a Multi-Disciplinary Design Team published an article in the magazine Bâtiment et Sécurité (October 2005) on The PolyCentric Tower. I very much enjoy giving practitioners a small flavour of this work, whenever I make presentations at conferences and workshops …
Colour image, from one of my Overhead Presentations ... showing The PolyCentric Tower (2005), developed by a French Multi-Disciplinary Design Team in response to Recommendation 18 in the 2005 NIST WTC Report. Click to enlarge.
.
Example B: In spite of a less than helpful submission (to put it mildly) from ISO TC92 Sub-Committee 4 … ISO 21542: ‘Building Construction – Accessibility & Usability of the Built Environment’ was finally published in December 2011 … but it was developed by a Sub-Committee of ISO TC59: ‘Buildings & Civil Engineering Works’ …
Colour image, from one of my Overhead Presentations ... showing the design of a notional Fire Evacuation Staircase, with an adjoining Area of Rescue Assistance, which responds directly to the 2005 NIST WTC Recommendations. See Figure 62 in ISO 21542:2011. Click to enlarge.
.
With the involvement and support of ISO Technical Committee 178: ‘Lifts, Elevators & Moving Walks’ during its long gestation … ISO 21542 is now able to indicate that all lifts/elevators in a building should be capable of being used for evacuation in the event of a fire. This is already a design feature in a small number of completed Tall Building Projects. Once more, this is no longer an option.
In addition … if a Fire Evacuation Staircase has a minimum unobstructed width of 1.5 m (from edge of handrail on one side of the staircase to edge of handrail on the opposite side) … this will be sufficient to facilitate the following tasks …
Assisted Evacuation by others, or Rescue by Firefighters, for those building users who cannot independently evacuate the building, e.g. people with activity limitations … shown above, on the right, is assistance being given by three people (one at each side, with one behind) to a person occupying a manual wheelchair ;
Contraflow Circulation … emergency access by firefighters entering a building and moving towards a fire, while people are still evacuating from the building to a ‘place of safety’ remote from the building … shown above, bottom left, is how not to design an evacuation staircase (!) ;
Stretcher Lifting … lifting a mobility-impaired person, who may be conscious or unconscious, on a stretcher ;
Firefighter Removal & Contraflow … shown above, top left, is removal of a firefighter from a building by colleagues in the event of injury, impairment, or a fire event induced health condition … while other firefighters may still be moving towards the fire.
Note that in a Fire Evacuation Staircase … all Handrails are continuous … each Stair Riser is a consistent 150 mm high … each Stair Tread/Going is a consistent 300 mm deep … and there are No Projecting Stair Nosings.
Most importantly … in order to assign sufficient building user space in the design of an Area of Rescue Assistance … ISO 21542 also provides the following Key Performance Indicator … just one aspect of a ‘maximum credible user scenario’ …
10% of people using a building (including visitors) have an impairment, which may be visual or hearing, mental, cognitive or psychological, or may be related to physical function, with some impairments not being identifiable.
Is There Any Connection Between Examples A & B ? There is, and it is a connection which is critical for public safety. The following Performance Indicator illustrates the point …
Innovative Structural Design – Perimeter Core Location – Design for Fire Evacuation – Evacuation for All
” A Building must not only remain Structurally Stable during a fire event, it must remain Serviceable for a period of time which facilitates:
Rescue by Firefighters of people with activity limitations waiting in areas of rescue assistance ;
Movement of the firefighters and those people with activity limitations, via safe and accessible routes, to Places of Safety remote from the building ;
With an assurance of Health, Safety & Welfare during the course of this process of Assisted Evacuation. “
[Refer also to the Basic Requirements for Construction Works in Annex I of the European Union’s Construction Product Regulation 305/2011 – included as Appendix II of the CIB W14 WG IV Reflection Document. Are the Basic Requirements being interpreted properly … or even adequately ??]
.
ANSWERS TO THE QUESTION …
The Greek Paper is included as Appendix I of CIB W14 WG IV Reflection Document … in order to show that Fire-Induced Progressive Damage is also an issue in buildings with a reinforced concrete frame structure. It is more straightforward, here, to concentrate on buildings with a steel frame structure.
a) Use of ‘Fire Resistance'(?) Tables for Structural Elements
We should all be familiar with these sorts of Tables. The information they contain is generated from this type of standard test configuration in a fire test laboratory …
… and this sort of criterion for ‘loadbearing horizontal elements’ in a fire test standard …
A single isolated loaded steel beam, simply supported, is being tested. As deflection is the only type of deformation being observed and measured … the critical temperature of the steel, i.e. the point when material strength begins to fail rapidly and the rate of beam deflection increases dramatically … is the sole focus for all stakeholders.
Using these Tables, it is very difficult to escape the conclusion that we are merely interior decorators … applying flimsy thermal insulation products to some steel structural elements (not all !) … according to an old, too narrowly focused, almost static (‘cold form’) recipe, which has little to do with how today’s real buildings react to real fires !
This ‘non-design’ approach is entirely inadequate.
.
With regard to the use of these Tables in Ireland’s Building Regulations (Technical Guidance Document B), I recently submitted the comments below to the relevant Irish AHJ. These same comments could just as easily apply to the use of similar Tables in the Building Regulations for England & Wales (Approved Document B) …
” You should be aware that Table A1 and Table A2 are only appropriate for use by designers in the case of single, isolated steel structural elements.
In steel structural frame systems, no consideration is given in the Tables to adequate fire protection of connections … or limiting the thermal expansion (and other types of deformation) in fire of steel structural elements … in order to reduce the adverse effects of one element’s behaviour on the rest of the frame and/or adjoining non-loadbearing fire resisting elements of construction.
In the case of steel structural frame systems, therefore, the minimum fire protection to be afforded to ALL steel structural elements, including connections, should be 2 Hours. Connections should also be designed and constructed to be sufficiently robust during the course of a fire incident. This one small revision will contribute greatly towards preventing Fire-Induced Progressive Damage in buildings … a related, but different, structural concept to Disproportionate Damage …
Disproportionate Damage
The failure of a building’s structural system (i) remote from the scene of an isolated overloading action; and (ii) to an extent which is not in reasonable proportion to that action.
Fire-Induced Progressive Damage
The sequential growth and intensification of structural deformation and displacement, beyond fire engineering design parameters, and the eventual failure of elements of construction in a building – during a fire and the ‘cooling phase’ afterwards – which, if unchecked, will result in disproportionate damage, and may lead to total building collapse. “
Coming from this background and heritage … it is very difficult to communicate with mainstream, ambient structural engineers who are speaking the language of structural reliability, limit state design and serviceability limit states.

At the end of Page 18 in NISTIR 7563 …
” 2.7.2 Multi-Storey Frame Buildings
In recent years, the fire performance of large-frame structures has been shown in some instances to be better than the fire resistance of the individual structural elements (Moore and Lennon 1997). These observations have been supported by extensive computer analyses, including Franssen, Schleich, and Cajot (1995) who showed that, when axial restraint from thermal expansion of the members is included in the analysis of a frame building, the behaviour is different from that of the column and beam analyzed separately.
A large series of full-scale fire tests was carried out between 1994 and 1996 in the Cardington Laboratory of the Building Research Establishment in England. A full-size eight-storey steel building was constructed with composite reinforced concrete slabs on exposed metal decking, supported on steel beams with no applied fire protection other than a suspended ceiling in some tests. The steel columns were fire-protected. A number of fire tests were carried out on parts of one floor of the building, resulting in steel beam temperatures up to 1000 °C, leading to deflections up to 600 mm but no collapse and generally no integrity failures (Martin and Moore 1997). “
Those were Experimental Fire Tests at Cardington, not Real Fires … on ‘Engineered’ Test Constructions, not Real Buildings !! And … incredibly, for a 2009 document … there is no mention at all of World Trade Center Buildings 1, 2 or 7 !?! Where did they disappear to, I wonder ? Too hot to handle ???
Computer Model Verification and Validation (V&V) are very problematic issues within the International Fire Science and Engineering Community. The expected outcome of a Model V&V Process, however, is a quantified level of agreement between experimental data (and, if available, real data) and model prediction … as well as the predictive accuracy of the model.
Now … please meditate carefully on the following …
NIST recommends that the technical basis for the century-old standard for fire resistance testing of components, assemblies and systems be improved through a national effort. Necessary guidance also should be developed for extrapolating the results of tested assemblies to prototypical building systems. A key step in fulfilling this Recommendation is to establish a capability for studying and testing components, assemblies, and systems under realistic fire and load conditions.
Of particular concern is that the Standard Fire Resistance Test does not adequately capture important thermally-induced interactions between structural sub-systems, elements, and connections that are critical to structural integrity. System-level interactions, especially due to thermal expansion, are not considered in the standard test method since columns, girders, and floor sub-assemblies are tested separately. Also, the performance of connections under both gravity and thermal effects is not considered. The United States currently does not have the capability for studying and testing these important fire-induced phenomena critical to structural safety.
Relevance to WTC 7: The floor systems failed in WTC 7 at shorter fire exposure times than the specified fire rating (two hours) and at lower temperatures because thermal effects within the structural system, especially thermal expansion, were not considered in setting the endpoint criteria when using the ASTM E 110 or equivalent testing standard. The structural breakdowns that led to the initiating event, and the eventual collapse of WTC 7, occurred at temperatures that were hundreds of degrees below the criteria that determine structural fire resistance ratings. “
The design approach outlined in NISTIR 7563 is not only very flawed … it lacks any validity … because very relevant and important real fire data has been totally ignored. The Cardington Experimental Fires were not all that they seemed.

c) Current ISO TC92 International Case Study Comparison
Structural Fire Engineering Design of an Airport Terminal Building serving the Capital City of a large country (which shall remain nameless) … constructed using Portal Steel Frames …
My first concern is that the Structural Fire Engineering Design has been undertaken in isolation from other aspects of the Building’s Fire Engineering Design.
On Page 3 of the Case Study Report …
” 4.2 Objectives & Functional Requirements for Fire Safety of Structures
The fire safety objectives of the airport terminal emphasize the safety of life, conservation of property, continuity of operations and protection of the environment. “
Should these not be the Project-Specific Fire Engineering Design Objectives ? Since when, for example, is ‘continuity of operations’ a concern in building codes ??
On Page 7 of the Case Study Report …
” 5.3 Identify Objectives, Functional Requirements & Performance Criteria for Fire Safety of Structure
The Fire Safety Objective of the Steel Structure: There should be no serious damage to the structure or successive collapse in case of fire.
The Functional Requirements are defined as the followings:
(1) Prevent or limit the structural failure in case of fire so as to prevent the fire from spreading within the compartment or to the adjacent fire compartment or the adjacent buildings (to prevent fire spread) ;
(2) Prevent or limit the partial structural failure in case of fire so as to protect the life safety of the occupants and firefighters (to protect life safety) ;
(3) Prevent or limit the structural deformation or collapse so as not to increase the cost or difficulties of the after-fire restoration (to reduce reconstruction cost).
One of the following Performance Requirements shall be met:
(1) The load-bearing capacity of the structure (Rd) shall not be less than the combined effect (Sm) within the required time, that is Rd ≥ Sm. (The maximum permitted deflection for the steel beam shall not be larger than L/400, and the maximum stress of the structure under fire conditions shall not be larger than fyT) ; or
(2) The fire resistance rating of the steel structure (td) shall not be less than the required fire resistance rating (tm), that is, td ≥ tm ; or
(3) Td – the critical internal temperature of the steel structure at its ultimate state shall not be less than Tm (the maximum temperature of the structure within required fire resistance time duration), that is Td ≥ Tm. (300 ℃) “
Once again … we see an emphasis on critical temperature, beam deflection (only), and material strength. L/400 is an impressive Fire Serviceability Limit State … a different world from L/20 or L/30 … but what about other important types of steel structural member deformation, e.g. thermal expansion and distortion ??
Furthermore … if there is a major fire in the area under the lower roof (see Section above) … because of structural continuity, any serious impact on the small frame will also have an impact on the large frame. For Structural Fire Engineering reasons … would it not be wiser to break the structural continuity … and have the small and large portal frames act independently ?
It is proposed that the Portal Frames will NOT be fully fire protected … just the columns, up to a height of 8 metres only. If ‘conservation of property’ and ‘continuity of operations’ are important fire engineering design objectives in this project … why isn’t all of the steel being fully protected ??? What would be the additional cost, as a percentage of the total project cost ?
What exactly is infallible about current Design Fires and Design Fire Scenarios ??? Not much. And in the case of this particular building, should a ‘maximum credible fire scenario’ be at least considered ?
And … what is the fire protection material, product or system being used to protect the Portal Frames ? Will it be applied, fixed or installed correctly ? What is its durability ? Will it be able to resist mechanical damage during the construction process … and afterwards, during the fire event ? What is the reliability of this form of fire protection measure ??
