Sustainable Fire Engineering

2015 Dublin Declaration on ‘Fire Safety for All’ Adopted !

2015-04-20:  After a lengthy, constructive and very interesting discussion which resulted in some important text revisions … on Friday afternoon, 10 April 2015, at the ‘Fire Safety for All’ Conference (www.fire-safety-for-all.ie) … all participants voted to adopt, support and promote the Dublin Declaration on ‘Fire Safety for All’ in Buildings !

With regard to International Distribution and Promotion of the Declaration … many readers of this Technical Blog belong to varied professional, social and business networks.  I would earnestly ask you to circulate the Declaration widely within those networks, and to actively seek the support of as many organizations and individuals as possible.  This support should be confirmed by means of a simple e-mail message to: fireox@sustainable-design.ie … and I will then add the names of supporters to the Fire Safety for All WebSite (www.fire-safety-for-all.ie).  Copies of the Declaration, in PDF Format, can also be downloaded from the WebSite.

Fire-Safety-4-All_smlThis Benchmark Declaration … an essential new reference document for all stakeholders and interested parties … draws a long-awaited, broad, distinct and stable line in the shifting sands of a rapidly evolving Sustainable Built Environment …

  1. As of April 2015, over 150 Countries and the European Union have ratified the United Nations Convention on the Rights of Persons with Disabilities (CRPD).  Since the Convention became an international legal instrument during 2008, however, the CRPD Preamble’s Paragraphs (g) and (v) have tended to receive insufficient public attention and scrutiny.  The Dublin Declaration on ‘Fire Safety for All’ in Buildings and the CIB W14 Research Working Group 5’s Reflection Document have been drafted with these two paragraphs very much in mind.
  2. Although a situation of serious risk for vulnerable building users … it is not appropriate to deal with ‘Fire Safety for All’ in Buildings under Article 11 of the U.N. Convention on the Rights of Persons with Disabilities (CRPD) … where situations of grave risk are handled, e.g. Extreme Man-Made Events, Hybrid Disasters, Severe Natural Events, Complex Humanitarian Emergencies … all amid Accelerating Climate Change & Variability.
  3. It is more appropriate, particularly since the publication of International Standard ISO 21542 (2011) with its expanded definition of Building Accessibility, that ‘Fire Safety for All’ be incorporated into Article 9 of the CRPD … in exactly the same manner that fire safety is fully integrated into everyday mainstream building use, and mainstream building fire safety codes and standards.  An improved and updated definition of Building Accessibility is contained in Principle 3 of the Dublin Declaration.
  4. Existing approaches to Fire Safety, Protection & Evacuation in Buildings for People with Activity Limitations … as described and illustrated in the notable examples of British Standard B.S. 9999 (2008), Singapore’s FSR 7 (2011), and Hong Kong’s Fire Safety Code Addendum (2014) … are technically inadequate, tokenistic, discriminatory, create barriers to social participation, and violate human rights.  Therefore, any further use or recourse to such existing approaches must be terminated immediately !

DUBLIN  DECLARATION  ON  ‘FIRE SAFETY FOR ALL’  IN  BUILDINGS
A Call to Action and Successful Implementation !

(Adopted in Dublin, 2015-04-10)

Meeting In  Dublin, Ireland … on Thursday and Friday, 9 and 10 April, 2015

In Co-Operation With  the International Council for Research & Innovation in Building & Construction (CIB), Rehabilitation International’s International Commission on Technology & Accessibility (RI-ICTA), the Global Alliance for Accessible Technologies & EnvironmentS (GAATES), and the EUropean Concept for Accessibility Network (EuCAN) ;

Recognizing  the integral and interdependent nature of the natural and human environments (social, built, virtual, economic and institutional) on this small planet Earth, our common home … and the need for harmonized principles to inspire and guide the peoples of the World in the enhancement of a human environment which cherishes the dignity, worth and many abilities of every person ;

Whereas  in the United Nations Charter, the U.N. Member States pledged their respect for, and the protection and observance of, fundamental human and social rights … and have determined to promote social development and better standards of living for all ;

Recalling  the Universal Declaration of Human Rights (UDHR), adopted on 10th December 1948 … which established a global framework of human and social rights – basic needs and protections – and fundamental freedoms for every person and communal gathering ;

Recalling Also  the Rio de Janeiro Declaration on Sustainable Social Development, Disability & Ageing, adopted on 11th December 2004 … which stressed the importance of the social aspects in Sustainable Human & Social Development ;

Mindful Especially  of the United Nations Convention on the Rights of Persons with Disabilities (CRPD), adopted on 13th December 2006 … the principal aim of which is to ensure that the human environment is sufficiently accessible to permit a vulnerable and major population group in all communities to safely exercise and enjoy the human and social rights and fundamental freedoms described in the 1948 UDHR ;

Working Towards  the achievement of justice, equality of opportunity, social inclusion, active participation and development for every person with an activity limitation in all communities … and recognizing that accessibility of the human environment is an essential prerequisite for the above, and that fire safety for all is a critical life safety component of that accessibility ;

Aware Always  of the universal reality that there is still a strong social stigma associated with disability and, particularly, mental ill-health … that much of the human environment is not accessible for all, and even where it is robustly mandated in law, the quality of that accessibility is poor … and that fire safety guidelines for people with activity limitations in buildings, if they exist, are inadequate and/or tokenistic, and rarely implemented ;

Welcoming the launch of the CIB Working Commission 14: Fire Safety – Research Working Group 5’s Reflection Document: Buildings & ‘Fire Incident Human Behaviour and Abilities’ which presents a practical examination and general overview of fire safety for all

.
Addressed to every Country and the European Union – those many Voluntary Parties to the U.N. Convention on the Rights of Persons with Disabilities – and the Politicians, Authorities Having Jurisdiction, State Agencies, Professional Bodies & Institutions, Non-Governmental Organizations, Charitable & Private Organizations, etc., based within those separate jurisdictions:

We Declare That The Following Principles Must …

Be carefully studied, successfully implemented, and independently monitored … supported by Benchmarking, reliable Data and Statistics, and the informed use of pertinent Accessibility & Fire Safety Related Performance Indicators …

Principle 1 – A Human Right

Full and effective accessibility of the Human Environment (social, built, virtual, economic and institutional) is a fundamental human and social right, i.e. a basic need, for people with activity limitations – it is an essential prerequisite for the safe exercise and enjoyment of those rights, protections and freedoms set down in the 1948 Universal Declaration of Human Rights and subsequent international rights instruments … and crucially, for their health, participation, inclusion and development in all communities.

Principle 2 – Successful Implementation

Successful accessibility implementation … meaning high quality accessibility performance in the built environment … is reliant upon:

  • A robust legal base mandating accessibility for all and fire safety for all ;
  • Determined political will ;
  • Sufficient public financial resources ;
  • A compassionate and understanding bureaucracy at all levels ;
  • Competent … meaning duly educated, trained and experienced in accessibility and fire safety design … spatial planners, architects, structural engineers, fire engineers, quantity surveyors, technical controllers, industrial designers, building managers, and people at all levels in construction organizations ;
  • Independent monitoring of accessibility and fire safety performance ;
  • Innovative, well-designed accessibility and fire safety related products and systems which can be shown to be ‘fit for their intended use’.

Principle 3 – Building Accessibility

Accessibility of a Building encompasses the complete cycle of independent use, in a dignified manner and on an equal basis with others … and includes the approach, entry and use of a building and its facilities, egress during normal conditions and removal from its vicinity … and, most importantly, safe evacuation during a fire incident to a place of safety which is remote from the building and reached by way of an accessible route.

Principle 4 – Design for Safe Evacuation

Accessibility design criteria must be infused into all of the practical, day-to-day work of building designers and, especially, in the development of project-specific fire engineering design objectives … and be applied from the initial stages of building design, through to the construction and reliable life cycle operation of vertical and horizontal fire evacuation routes facilitating contraflow, areas of rescue assistance, fire safety related signage, controls and fittings, fire prevention and protection measures, fire safety management procedures, routes to and locations of places of safety, etc., etc.
• Evacuation way finding in buildings must be intuitive and obvious ;
• 3 Keywords for building designers must be: reality – reliability – redundancy.

Principle 5 – Accessible EICT’s

Electronic, information and communication technologies are ubiquitous in today’s complex built and virtual environments.  During a real fire incident in a building, they serve a function which is critical for the safety of all building users and firefighters, property protection, minimizing environmental damage and harm, and sustainability. For that reason, they must have a control and/or user interface which is accessible for all.

Principle 6 – Fire Safety Skills

People with activity limitations who occupy or use a building frequently must be included in all practice fire evacuations, in order to learn the skill of safe independent evacuation to an accessible place of safety remote from the building.  During a real fire incident, evacuation assistance provided by other building users or rescue by firefighters, and the time spent waiting for that assistance or rescue in the building must be kept to an absolute minimum.

People with activity limitations must be actively encouraged to participate in fire safety preparatory planning and regular practices … and, without exception, must be consulted and included in all activities concerning their own evacuation from a building.

Management systems and fire protection measures in buildings are never 100% reliable.  People with activity limitations must, therefore, be actively encouraged to be self-aware in situations of risk, and facilitated in learning the skill of self-protection.

Principle 7 – Reasonable Spatial Provision

Reasonable spatial provision must be allocated in a building for the needs of real users, who vary in the range of their individual behaviour and abilities … and for the real building user population profile which, avoiding discrimination, must reflect a society as a whole.  Concerning fire safety for all and the necessary size, for example, of an area of rescue assistance which adjoins a fire evacuation staircase on every floor in a building … the following indicators, exclusive of extra provision for assistants, must guide the architect and fire engineer in the collaborative design process:

(a)  Minimum reasonable provision for people with disabilities in a building – 10% of design occupant/user population ;

(b)  Minimum reasonable provision for people with activity limitations in a building … 15% of design occupant/user population.

Principle 8 – Building Management

Building managers must ensure that fire safety for all preparatory planning is effective, and that practices are held regularly … before any real fire incident occurs.  And as part of their normal, day-to-day functioning … managers must be fully aware that, without due attention to accessibility-related services, product maintenance and occupant/user welfare policies, the quality of accessibility in a building will rapidly deteriorate.

Personal Emergency Evacuation Plans (PEEPS) must not be used to limit or restrict access to any part of a building and its facilities.

Principle 9 – Firefighters

Firefighters must be trained to interact with and rescue people with activity limitations from buildings, using procedures and equipment which will not cause injury to either.  Fire services must ensure that they operate such procedures and possess such regularly serviced equipment.

Emergency service organizations must operate reliable systems to notify the fire services of emergency situations, which are accessible for all and useable by the public at all times.

.

APPENDIX – Terms & Definitions

Area of Rescue Assistance:  A sufficiently large building space directly adjoining, and visible from, a main vertical evacuation route – robustly and reliably protected from heat, smoke and flame during and after a fire – where people may temporarily wait with confidence for further information, instructions, and evacuation assistance or rescue, without obstructing or interfering with the evacuation travel of other building users.

Contraflow Circulation in a Fire Building:  Emergency access by firefighters or rescue teams into a building and towards a real fire … while building users are still moving away from the fire and evacuating the building.

Evacuation from a Fire Building:  To withdraw, or cause to withdraw, all users from a building which is on fire … in pre-planned and orderly phased movements to an accessible place of safety remote from the building.

Fire Compartmentation:  The division of a building into fire-tight compartments by fire, smoke and heat resisting elements of construction, in order to …
a)  contain an outbreak of fire, including any smoke and heat generated by the fire ;
b)  prevent damage, within the building, to other adjoining compartments and spaces ;
c)  protect a compartment interior from external fire attack, e.g. fire spread across the building’s facade or from an adjacent building ;
d)  minimize adverse, or harmful, environmental impacts outside the building.

Human Health:  A state of complete physical, mental and social wellbeing, and not merely the absence of disease or infirmity.

People with Activity Limitations (E) / Personnes à Performances Réduites (F):  Those people, of all ages, who are unable to perform, independently and without aid, basic human activities or tasks – because of a health condition or physical / mental / cognitive / psychological impairment of a permanent or temporary nature.

The above Term includes …

  • wheelchair users ;
  • people who experience difficulty in walking, with or without a facilitation aid, e.g. stick, crutch, calliper or walking frame ;
  • frail, older people ;
  • the very young (people under the age of 5 years) ;
  • people who suffer from arthritis, asthma, or a heart condition ;
  • the visually and/or hearing impaired ;
  • people who have a cognitive impairment disorder, including dementia, amnesia, brain injury, or delirium ;
  • women in the later stages of pregnancy ;
  • people impaired following the use of alcohol, other ‘social’ drugs e.g. cocaine and heroin, and some medicines ;
  • people who suffer any partial or complete loss of language related abilities, i.e. aphasia ;
  • people impaired following exposure to environmental pollution and/or other irresponsible human activities, e.g. war and terrorism ;

and …

  • people who experience a panic attack in a real fire situation or other emergency ;
  • people, including firefighters, who suffer incapacitation as a result of exposure, during a real fire, to smoke and poisonous or toxic substances, and/or elevated temperatures.

Place of Safety:
•  Any accessible location beyond a perimeter which is [100] metres from the fire building or a distance of [10] times the height of such building, whichever is the greater ;   and
•  Where necessary triage can safely be rendered … and from where effective medical care and supervision can be organized and provided within one hour of injury (the ‘golden hour’) ;   and
•  Where people can be identified.

Note: If there is a risk of an explosion associated with a fire – multiply the numbers in square brackets above by 4.

Progressive Damage in Fire / 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.

Note: Fire-induced progressive damage may commence long before there is any breach in the integrity of a fire compartment’s boundaries.

Real Fire:  A fire which develops in a building and is influenced by such factors as the type of building and its occupancy (numbers, abilities and activities) ;  the combustible content (fire load) ;  the ventilation, geometry and thermal properties of the fire compartment or building space (should no fire compartmentation exist) ;  the fire suppression systems in the building, and the actions of firefighters.

Skill:  The ability of a person – resulting from proper training and regular practice – to carry out complex, well-organized patterns of behaviour efficiently and adaptively, in order to achieve some end or goal.

Social Environment:  The complex network of real and virtual human interaction – at a communal or larger group level – which operates for reasons of tradition, culture, business, pleasure, information exchange, institutional organization, legal procedure, governance, human betterment, social progress and spiritual enlightenment, etc.

Social Rights:  Rights to which an individual person is legally entitled, e.g. the right to free elementary education (Art.26(1), UDHR), but which are only exercised in a social context with other people, and with the active support of a competent legal authority, e.g. a Nation State.

Social Wellbeing:  A general condition – in a community, society or culture – of health, happiness, creativity, responsible fulfilment, and sustainable development.

Virtual Environment:  A designed environment, electronically generated from within the built environment, which may have the appearance, form, functionality and impact – to the person perceiving and actually experiencing it – of a real, imagined and/or utopian world.

‘Fire Safety for All': Open Call for Innovative Products & Systems

2015-02-02:  This is NOT … I repeat NOT … a small niche market in the Global Multi-Billion Euro Fire Safety & Protection Related Construction Industrial Sector !   This IS the whole nine yards !!

This is an Open Call for Innovative, Well-Designed Fire Safety / Protection and Accessibility Related Construction Products and Systems, Other Measures and Means, Mechanical and Electronic Devices, ETC, ETC, ETC, ETC !

This Call is particularly aimed at Manufacturers, Suppliers and Distributors in China, India, Japan, and Mainland Europe !

We want to see ‘Real’ Products and Systems, Measures and Means, Mechanical and Electronic Devices, ETC, ETC, ETC, ETC … not flashy brochures … at the 2015 Dublin ‘Fire Safety for All’ Industrial Exhibition, on 9 & 10 April !

.

An Accessible Building is Safer, Easier to Use and More Comfortable for ALL Building Users

If Fire Safety for All is properly considered at Building Design Stage :
• Buildings are easier to understand (intuitive) during a Real Fire Evacuation
Fire Evacuation Routes (obvious) are easier to find and to use
• Everyone can safely evacuate a Building on Fire – no more tragic tales about people being left behind in multi-storey schools and offices
RealityReliabilityRedundancy – are the 3 Essential Keywords

Client Organizations: A Building which is NOT Accessible is difficult, if not impossible, for everybody to evacuate during a real fire incident !

So …

Grab a Bicycle – Get a Horse – Take a Train or a Plane – Come to Dublin in April !

‘Fire Safety for All’ Update: Dublin Declaration & Press Release

2015-02-01:  This important Event is still a few months away, but the following update will be of interest …. a mixture of some good news and some bad news …

Fire-Safety-4-All_smlTo Register / To Attend … please go to the Event WebSite: www.fire-safety-for-all.ie … places are limited in the New Conference Venue.

.

1.  2015 Dublin ‘Fire Safety for All’ Declaration – A Call to Action & Successful Implementation !

From the beginning, we promised that this would not be a polite gathering in Dublin.  It will, instead, be a time for hard work and straight talking by everybody attending … and a good opportunity to have some fun also.  Dublin is a very ‘sociable’ city !

As an indication of our serious intent … please now download and examine the Proposed 2015 Dublin Declaration on ‘Fire Safety for All’ in Buildings (PDF File, 153 Kb) …

3.  Embarrassment about Original Conference Venue

Accessibility of a Building … encompasses the complete cycle of independent use, in a dignified manner and on an equal basis with others … and includes the approach, entry and use of a building and its facilities, egress during normal conditions and removal from its vicinity … and, most importantly, safe evacuation during a fire incident to a place of safety which is remote from the building and reached by way of an accessible route.

As I write … Ireland has a truck load of accessibility-related National Building Regulations and EU Safety at Work Law (transposed at national level a long, long time ago).  We have strong Equality Law.  We have ease of access to accessibility-related International Standards (such as ISO 21542: 2011) and National Standards from other European Countries, North & South America, and Asia.  We have accessibility-related National Guidance Documents coming out of our ears, and easy access to all sorts of other guidance from around the world.  Lots and lots and lots and lots of paperwork, in digital and hardcopy formats !

Ireland today … is still one of only a few remaining countries which have yet to ratify the United Nations Convention on the Rights of Persons with Disabilities (CRPD), the principal aim of which is to ensure that the Human Environment (including the built, social, economic, virtual and institutional environments) is sufficiently accessible for people with activity limitations to participate positively in all aspects of their local communities … a basic human right, which every able-bodied person takes for granted !

” This is not just a national disgrace, it is a huge embarrassment for our country when you consider that the European Union itself and most of the EU’s Member States have already ratified this UN Convention.”

AND … as I look around Dublin … the City is NOT accessible for its many vulnerable residents and foreign visitors !

Dublin Castle Printworks Building – Main Entrance

Colour photograph showing the Main Entrance to Dublin Castle’s Printworks Building.  Telepathy is required to be ‘aware’ that there is a ramp located way down at the far end of the building.  Notice the limited extent of ground tactile information at the bottom of the steps in the foreground, and the unmarked glazing on the left of the Entrance Doors above.

Are you sitting comfortably ?   Then I will tell you a short story … a ‘real’ story, not a fairy tale … about the Original Conference Venue …

Mr. Sean Sherlock, T.D., Minister of State at Ireland’s Department of Foreign Affairs with responsibility for Overseas Development Aid, has agreed to open the Event on the evening of Thursday, 9 April 2015.  All of Irish Aid’s Partner Countries in Africa have ratified the UN Convention on the Rights of Persons with Disabilities.

Given the serious, socially transformative topic of this Conference … the Minister had also kindly offered to waive the fee for the hire of the Printworks Building in Dublin Castle – a very prestigious location in the City, and a building which was been extensively refurbished in time for Ireland’s recent Presidency of the European Union.  The audio-visual fit-out for this building is magnificently elaborate.  Most unfortunately, the building’s accessibility is entirely inadequate (ATROCIOUS would be a better word to describe it!).

Dublin Castle Printworks Building – Set Down Area

Colour photograph showing a marked Set Down Area at the front of Dublin Castle’s Printworks Building.  Bollards prevent a Taxi from dropping off a passenger, who uses a wheelchair, at the bottom of the ramp.

However, with the right attitude and positive co-operation from the Venue Management Team, many improvements to the building’s accessibility could have been made for the Conference.  From the beginning, however, the Management Team’s response to this issue was negative.

” It is entirely unacceptable that this State’s New and Heritage Building Stock is designed, constructed, and/or managed without a full and proper consideration … and successful implementation … of Accessibility for All and Fire Safety for All ! “

Dublin Castle Printworks Building – Main Entrance Steps

Colour photograph showing, from above, the Main Entrance Steps of Dublin Castle’s Printworks Building.  Also notice the hazardous lack of visual colour contrast in platform and step surfaces.

The Venue Management Team has refused to honour the Minister’s waiver.

Dublin Castle Printworks Building – Top of Ramp

Colour photograph showing the Top of the Ramp at the side of Dublin Castle’s Printworks Building.  Notice the lack of ground tactile information.

We have had no other option but to move the Conference and Workshop to a far better Venue just around the corner … the Radisson Blu Hotel in Golden Lane, Dublin.

Dublin Castle Printworks Building – Bottom of Ramp

Colour photograph showing the Bottom of the Ramp at the side of Dublin Castle’s Printworks Building.  Notice the difficult approach to the Ramp, and also no indication of where there are level surfaces to rest when using the Ramp.

A Building which is NOT Accessible is difficult, if not impossible, for everybody to evacuate during a real fire incident …

‘Rigorous enforcement of building codes and standards by state and local agencies, well trained and managed, is critical in order for standards and codes to ensure the expected level of safety.  Unless they are complied with, the best codes and standards cannot protect occupants, emergency responders, or buildings.’

(2005 U.S. NIST NCSTAR 1: Final Report on the Collapse of the World Trade Center Towers … Page 202, Chapter 9: Recommendations)

2015 Paris Hive Attacks & Fire Engineering for Urban Resilience !

2015-01-31:  The beginning of this 21st Century is deeply unsettling … history is catching up on us, and old certainties are crumbling before our eyes …

The recent, extremely violent Paris Hive Attacks … which occurred between Wednesday and Friday (7-9 January 2015) … have again shown that co-ordinated attacks on a small number of carefully chosen, low-level targets can be just as effective in causing widespread social and economic disruption in a City as a single attack on a high-level target.  Search for our previous detailed discussion, here, on the 2008 Mumbai ‘Hive’ Attacks.

On this tragic occasion, the attacks happened in Europe … not, as before, in far-off India.

Following the 2001 WTC 9-11 Attacks in New York City … the U.S. National Institute of Standards and Technology (NIST), in 2005 and 2008, recommended that these Building Types should be treated as ‘Risk Priorities’ …

• Tall / High-Rise Buildings ;
• Iconic Buildings ;
• Buildings Having a Critical Function ;
• Buildings Having an Innovative Design.

However, a typical medium-rise office building (in Paris) and off-street supermarket do not fall into the above categories … another indication that the NIST Recommendations must soon undergo a thorough international review and updating.

In the real world, the whole urban and sub-urban infrastructure of a City is at risk from Extreme Man-Made Events … one more risk among significant others, i.e. Hybrid Disasters (e.g. 2011 Fukushima Nuclear Incident), Severe Natural Events (e.g. earthquakes, typhoons, tsunamis) and Complex Humanitarian Emergencies (e.g. mass human migrations, regional famines).  And with 50% of the world’s population already living in Cities, and substantial urban population growth projected over the coming decades … it is clear that, in the short to medium term, Cities must become much more resilient.  Search for our continuing discussion, here, about Sustainable Urban Resilience.

In this context, compliance solely with the minimal and limited fire safety objectives in current national legislation – from whatever source around the world – is so far from being either adequate or acceptable … that it is no longer worth a moment’s consideration.

A Fire Engineering which is ‘fit for purpose’, i.e. is both ethical and professional, in today’s complex and dynamic Human Environment … has an essential and critical part to play in the realization of a Safe, Resilient and Sustainable Built Environment for All !

Global Event: ‘Fire Safety for All’ in Buildings – Reboot & Reload !

2014-12-09:  FireOx International, the Fire Engineering Division of Sustainable Design International Ltd., is very pleased and proud to present the following Global CSR (Corporate Social Responsibility) Event

Fire Safety for All !9 & 10 April 2015 – Dublin Castle, Ireland

‘Fire Safety for All’ in Buildings – Reboot & Reload !
[ www.fire-safety-for-all.ie ]

Co-Sponsored by CIB & RI-ICTA
Kindly supported by Fáilte Ireland

This will not be a polite gathering intended just for an Irish audience, or even for Europeans … this is a Global Event – a catalyst for Substantive Social Transformation everywhere !

Within the professional discipline of Fire Engineering … either a building is Fire Safe or it is not ;  the design philosophy of the fire engineer is irrelevant.  Similarly, now, we must begin to think and act in the simple terms of a building either being Accessible for All, or not.  And if the building is accessible for all, does it tick all of the right accessibility boxes well, i.e. effectively ?

While building fire safety codes and standards exist in almost every country … guidelines relating to the Fire Safety of People with Activity Limitations – IF those guidelines exist at all – are technically inadequate, entirely tokenistic, blatantly discriminatory, and rarely implemented.

This is a very significant obstacle to Effective Building Accessibility everywhere !!

Accessibility is now understood to mean the full cycle of independent building use, in an equitable and dignified manner … and this term includes the approach, entry to and use of a building, egress during normal conditions and removal from the vicinity of the building … and, most importantly, evacuation during a fire incident to a ‘place of safety’ which is remote from the building.  (ISO 21542 : 2011)

Cogently mandated in the United Nations Convention on the Rights of Persons with Disabilities (2006) … the CRPD’s principal aim is to ensure that the Built, Social, Economic and Virtual Environments are sufficiently ‘accessible’ to permit a vulnerable and major(!) population group in all of our societies to enjoy the fundamental freedoms and human rights described in the Universal Declaration of Human Rights (1948).

Refer to Preamble Paragraph (g) in the UN Convention …

‘ Emphasizing the importance of mainstreaming disability issues as an integral part of relevant strategies of sustainable development,’

and to … Article 3 (General Principles), Article 9 (Accessibility), Article 11 (Situations of Risk & Humanitarian Emergencies), Article 19 (Living Independently & Being Included in the Community), Article 20 (Personal Mobility), Article 24 (Education), Article 27 (Work & Employment), Article 31 (Statistics & Data Collection), Article 32 (International Co-Operation), and Article 33 (National Implementation & Monitoring).

The focus of this event, therefore, is Real Accessibility.  In other words, Effective Accessibility for People with Activity Limitations (which includes people with disabilities, and children under the age of 5 years, frail older people, women in the later stages of pregnancy, and people with health conditions, etc.) … an accessibility which actually works well for all potential building users.  And it is appropriate also, now, to introduce the concept of Monitoring and Targeting this ‘real’ accessibility … independently, i.e. by 3rd Parties !

It is time to Reboot this ridiculous, professionally negligent and obsolete old system … Reload with innovative and practical building design, construction, management and personal self-protection solutions … and Implement !

FireOx ‘Fire Safety for All’ Matrix – Revised & Updated

2014-10-17:  Within the professional discipline of Fire Engineering … either a building is ‘fire safe’, or it is not.  The Design Philosophy of the Fire Engineer is irrelevant.  In fact, nearly everybody involved with fire safety in buildings would collapse in a fit of laughter at the delusional notion that a design philosophy was relevant.  People’s lives are at stake !

Similarly, now, we must begin to think and act in the simple terms of a building either being ‘accessible’, or not.  At stake, this time, is the quality of life and living for very many vulnerable people in all of our societies.

Accessibility for All, according to International Standard ISO 21542 (2011) … includes the approach, entry to and use of a building, egress during normal conditions and removal from the vicinity of the building … and, most importantly, evacuation during a fire incident to a ‘place of safety’ which is remote from the building.

Concerning that All above … FireOx International’s ‘Fire Safety for All’ Matrix shows who exactly we are talking about … and who must be considered in the development of a Fire Safety Strategy for every building … not just some buildings !

This is not just good design practice … it is also mandated in International Human Rights Law.

Upcoming CIB/NIST Workshop on Structural Reliability in Fire ?!?

2014-05-16:  Anybody with even the slightest interest in the Future Development of Fire Engineering Design, and Structural Fire Engineering in particular, should pay attention to the proceedings of an upcoming CIB/NIST Workshop, which will be held on 21-22 May 2014, at the NIST Campus in Maryland, USA …

CIB/NIST Fire Resistance/Resistant/Resisting/Resistive Structures Workshop

It is essential to read 3 White Papersproduced by three separate teams of experts, contracted by NIST, in advance of the Workshop … to get a ‘real’ flavour of how discussions may, or may not, develop next week.  All three papers are available to download from the NIST WebSite (and the links below).  I suggest that you get your hands on them … ASAP !

1.   Fire Behaviour of Steel Structures (March 2014).  20 Pages, 786 Kb.
2.   State-of-the-Art on Fire Resistance of Concrete Structures: Structure-Fire Model Validation (March 2014).  32 Pages, 1.26 Mb.
3.   Fire Resistance of Timber Structures (March 2014).  20 Pages, 998 Kb.

After reading these 3 NIST White Papers … I was not surprised by the large number of ‘unknowns’, or the enormous gaps in our ‘knowns’ …

Taken in whole and all together, however, the three documents are a public confirmation that today’s general practice of Fire Engineering is more akin to that of mid-19th Century Alchemy.  Blinkered practitioners are isolated from the building design process … because they have no understanding of that process, and have no means of effective communication with the many other design disciplines involved.  And minimal, i.e. ‘cost-effective'(?), compliance with the limited and inadequate fire safety objectives in current building codes/regulations is widely regarded as the one and only target for their efforts … a minor one compared to the fundamental, long-term target of realizing a Safe, Resilient and Sustainable Built Environment for All.  At the same time, frontline fire service personnel are forced to operate on shoestring budgets … and, when a fire emergency inevitably occurs, they are regarded as nothing more than an expendable resource.

!!  Structure … Does Not A Building Make  !!

Some comments on the 3 NIST White Papers …

A.  The Papers contain a number of important technical errors:

  • A similar Introduction in two of the Papers refers only to the 2005 NIST Report (NCSTAR 1) on the 9-11 Collapse of WTC Buildings 1 & 2 in New York City, which contained 30 Recommendations.  However, NIST published a later Report in 2008 (NCSTAR 1A) on the Collapse of WTC Building 7, which contained a further 13 Recommendations … 1 new, and 12 revised/updated from the earlier 2005 Report.
  • There is a reference in one of the Papers to a 1989 European Directive on Construction Products (89/106/EEC), and as later amended.  This Directive was repealed, in 2011, by Article 65 of the new European Union (EU) Regulation No.305/2011 on Construction Products.  Unlike a Directive, a Regulation is addressed directly to the EU Member States, and does not permit any flexibility with regard to national implementation. Annex I of Regulation 305/2011 sets out 7 Basic Requirements for Construction Works:

–  Mechanical resistance and stability ;
–  Safety in case of fire ;
–  Hygiene, health and the environment ;
–  Safety and accessibility in use ;
–  Protection against noise ;
–  Energy economy and heat retention ;
–  Sustainable use of natural resources.

Concerning fire safety in buildings … it is incorrect to state, or even suggest, that only the second Basic Requirement is relevant … a building must satisfy all of the Basic Requirements taken together, i.e. the 7 Basic Requirements are inter-dependent.

B.  Having carefully read the Papers … none of the expert teams appear to have paid any attention to any of the NIST Recommendations, in either the 2005 or the 2008 Reports !   Note well that two separate series of posts on both sets of NIST Recommendations have been carried here on this Technical Blog.

C.  If we have learned anything from the WTC 9-11 Building Collapses, it is that the Fire Engineer must be able to communicate effectively with other mainstream building design disciplines … especially ‘ambient’ structural engineers who speak the language of Structural Reliability, Limit State Design and Serviceability Limit States.  The Fire Engineer must also become an active participant in the creative, trans-disciplinary process of design.  These issues have not been seriously considered in any of the Papers.

D.  All of the Papers lack a common and precise starting point … relevant structural fire engineering concepts are either not defined or badly defined … and the ‘dynamic, complex architectural interaction between a building’s structure and fabric under conditions of fire’ requires immediate and urgent investigation …

Structural Reliability

The ability of a structural system to fulfil its design purpose, for a specified time,
under the actual environmental conditions encountered in a building.

Structural Fire Engineering

Those aspects of fire engineering concerned with structural design for fire …
and the dynamic, complex architectural interaction between a building’s structure and
fabric, i.e. non-structure … under conditions of fire and its immediate aftermath,
including but not confined to the ‘cooling phase’.

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.

[ *fire serviceability limit states ]

.

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 and Disproportionate Damage are fundamental concepts in the Fire Engineering Design of All Buildings ! ]

.

E.  It is not acknowledged in any of the Papers that the Fire Safety Objectives in Current Building Codes/Regulations are, of necessity, limited in scope … and entirely inadequate in the context of Annex I in EU Regulation 305/2011, and the long-term goal of realizing a Safe, Resilient and Sustainable Built Environment for All.  Refer to the updated Scope, Aims & Objectives of CIB Working Commission 14: ‘Fire Safety’.

F.  Once and for all … use of the term Fire Resistance (and any number of variations thereof, e.g. resistant, resisting, resistive, etc.) in connection with any aspect of structural performance in fire … is ridiculous !   It is roughly comparable to use of the term Fire Proof during the first half of the 20th Century.

G.  Finally, for now … the current unwise focus on Crude Pass/Fail Results from the ‘standard fire’ testing of single loadbearing structural elements must evolve … must be transformed into the more detailed and precise measurement of all aspects of ‘real’ structural system performance over the full duration of a ‘design’ fire (including the cooling phase afterwards) … using a much wider range of performance monitoring equipment, e.g. short wave infra-red thermography.

.

It is no longer acceptable for Fire Engineering to exist in an isolated Twilight Zone … completely removed from the everyday realities of Mainstream Building & Construction.

Model Disability Policy Statement for Educational Establishments

2014-04-21:  Notwithstanding the, by now, well-established existence of the United Nations Convention on the Rights of Persons with Disabilities (UN CRPD), International Standard ISO 21542: ‘Building Construction – Accessibility & Usability of the Built Environment’, a host of other national accessibility standards, and a plethora of accessibility design guidance materials … not every ‘real’ site, or building, or built environment, situation is covered.  It would be physically impossible.

Unless it is fixed in your mind … or, more importantly, in the ‘group-thinking’ of an organization … that Accessibility-for-All should be, for example, both independent (i.e. it is not necessary for a person to have an assistant) and inclusive (i.e. friends can do things together and no special deal is made about accessibility for one person) … it can be very difficult to emerge from beneath the weight of those documents referred to above … and to apply important disability-related principles flexibly and adaptively in the real world.

At a recent meeting with some teachers in an Irish school (which shall remain nameless) … I advised that a very good and positive start can be made by discussing together and agreeing on a Disability Policy Statement, which will help to guide future actions.  More steps are required, of course, but those will come later.

2012 Doha Shopping Mall Fire – 5 Jail Sentences for Negligence !

2013-07-19:  Once upon a time, back in 1979, when I was flying to Sydney, Australia … one of the scheduled stops on the route was Bahrain and the New International Airport Terminal there.  In spite of the flashy and expensive building, I noticed how obsolete looking (and functioning) were the fittings in the toilet area.  Could it possibly be, I wondered, that the Arab Gulf Region was being supplied with shoddy, second rate construction products from you-know-where ??

Fast forward to a few years ago … in Riyadh, Saudi Arabia … and I encountered one building – the same building – where one half had a 110 Volt electrical supply, and the other half had a 220 Volt supply.  Amazing !?!   Two different consultants, or contractors, or whatever … one from North America, and the other from Europe … with the Saudis in the middle, having to tolerate this nonsense !!

'Villaggio' Shopping Mall Fire (Doha City in Qatar) - 28 May 2012

Photograph taken by Brian Candy. 2012-05-28. Click to enlarge.

DOHA City Fire – Monday, 28 May 2012 …

I distinctly remember that some Irish people who had actually witnessed the Fatal Fire Incident at the ‘Villaggio’ Shopping Mall (www.villaggioqatar.com), in Doha (capital city of Qatar) … were afterwards talking to Mr. Joe Duffy, on the lunchtime ‘Liveline’ Programme (Ireland’s RTE Radio 1 Station).

19 People were killed on that Monday morning in Doha … 13 Children, 4 Teachers, and 2 Firefighters.  Many more were injured from inhaling toxic smoke.

According to various news reports … an electrical fire, caused by a light fitting (which was not ‘fit for its intended use’) in a Nike Shop, engulfed a section of the shopping centre … spreading to the Gympanzee Drop-and-Shop Childcare Centre on the first floor.

The staircase leading to the Childcare Centre collapsed … trapping victims inside.  One of their fire exits led directly to the seat of the fire, while the other fire exit was locked from the outside.

In addition, the ‘Villaggio’ – a luxury mock-Italian shopping centre (one of the most popular in the country !) where customers could ride around Venetian-style Canals, in Venetian-style Gondolas – was later found to be in breach of legislation because Essential Fire Safety Measures were either inadequate or missing, at the time of the fire: the fire sprinkler system was not working properly; inflammable paint and decorative mouldings were used in the construction; the building did not have effective fire evacuation procedures in place; the building was not equipped with proper fire-fighting equipment; and the fire alarm wasn’t loud enough.

A Qatari Court – Thursday, 20 June 2013 …

The recent outcome from this Qatari Court Case has been nagging at me ever since I saw the news on Al Jazeera (English) … www.aljazeera.com

Only Some of the People having Control / Responsibility were convicted for the Negligence which resulted in the 19 Deaths, and many injuries, at the 2012 ‘Villaggio’ Fatal Fire Incident.

Four people received six-year jail terms, while the fifth received a five-year term.  All five are currently out on appeal, and will remain out of custody until the appeals process is completed.

Those convicted include Two Co-Owners of the Childcare Centre, and Members of the Mall’s Management Team.  Sheikh Ali Bin Jassim Al Thani, one of the co-owners, is also currently Qatar’s Ambassador to Belgium … while Iman Al-Kuwari, the other co-owner, is the daughter of Qatar’s Culture Minister.

Two other defendants, including the Mall’s Assistant Manager and Head of Security, were cleared of all charges.

.

Other People having Control / Responsibility were also Careless, Incompetent, and Negligent …

RF-Based Firefighter Communication Performance in Buildings

2013-05-22:  Whatever Service Providers claim … every day, we experience mobile/cell phone reception variability, drop-off and failure in buildings … whether we are fully conscious of it or not.  It’s inconvenient, but all we have to do is change location, even slightly … and ‘re-dial’.  However, if we are travelling on a train or bus, and it enters a tunnel … the problem can be annoying, as the situation is beyond our control !

On the other hand, however … not too far from where I live, there is an art house cinema with underground screens on different levels.  In this particular case, mobile/cell phone reception failure can be a positive joy – it will not be necessary to listen to someone else’s loud conversations during the film !

BUT … emergency first responders use radio frequency-based communication systems during the normal course of their work … and in the current built environment, these systems can also be unreliable.  Improved climate resilience in our future building stock will make matters worse.  So, it makes a lot of sense to take this issue seriously now !

Fire Departments equip their firefighters with a Radio Frequency-Based Personal Alert Safety System (PASS) … also known as an Automatic Distress Signal Unit (ADSU) … which sends out a signal to a fire incident base / control centre / command post when the firefighter is motionless or in distress, with a clear indication of his/her location … or, if necessary, a general warning can be sent from the fire incident base / control centre / command post to all firefighters to evacuate a building immediately … for example, if extensive structural collapse is imminent.

Recently, the National Institute of Science & Technology (USA) issued Technical Note 1792.  I have just a few short comments to make before jumping into the document …

1.   The Empire State Building and a Subway Station in New York City are both iconic building types … and unusual, in the context of the USA generally … but not so in Europe, with our long tradition for ‘hard/heavy’ construction.  Challenging environments for radio frequency-based communication systems are encountered in our basement / underground building types, and low-rise complex building types … never mind high-rise and tall buildings.

2.   Outside buildings, adequate external access routes for Firefighting Vehicles are mandated in building codes and standards … and Firefighter Lifts are provided inside buildings, etc., etc., etc.  Facilitating reliable radio frequency-based emergency communications should become a normal part of thinking about … and designing for … Safe Firefighter Access.  And … before new buildings are occupied, it should become routine to carry out an emergency communications check, as part of a wider collaborative effort between Building Management Teams and Local Fire Services.

3.   This NIST Technical Note is further evidence … as if any more evidence were needed … that it is a continuing and difficult process to fully implement the 2005 & 2008 NIST WTC 9-11 Recommendations.  To date, the easier low hanging fruit (system and procedural inadequacies !) have been tackled, which may be presented and/or described as substantive changes in building codes and standards … mere window dressing … tokenism, at its worst !   However, as discussed here before many times, some European countries continue to completely ignore these important NIST Recommendations.

NIST TN 1792 – Summary & Conclusion (Page 59)

Radio Frequency (RF) PASS Tests were performed in a New York Subway Station and the Empire State Building because these types of structures provide challenging RF propagation-channel environments.  In the Subway, the RF PASS systems were limited in their ability to communicate beyond the initial entrance level.  Without the use of repeaters, most of the systems could communicate only a short distance beyond the bottom of the stairwell that connected the token booth corridor to the street.  Two systems used repeaters to extend the coverage area.  When a repeater was located at the base of the stairwell leading up to the street, those two systems were able to communicate the RF PASS alarms between the street level and the first passenger platform.  However, with only a single repeater, neither of the two repeater systems was able to communicate between the external receive site and the second passenger level.  This suggests that for structures with sizable subterranean sections, a repeater system will likely be required to reach an external incident command post.  If the structure has multiple subterranean levels of increasing depth, a multiple-hop relay system will likely be necessary to ensure the reliability of the communication channel.

NIST TN 1792 - Figure 16: 'Subway + System 4 Performance'

NIST TN 1792 – Figure 16: ‘Subway + System 4 Performance’. Click to enlarge.

In the path-loss measurements and analysis performed at five frequencies, ranging from 430 MHz to 2405 MHz, there are several important insights.  Based on the upper adjacent values in the box-plot statistical representation of the path-loss data from the Empire State Building (see Figure 36), path-loss values of 140 dB to 175 dB are possible for high-rises.  For the Subway, the path-loss values exceed 210 dB to 240 dB at the lower two passenger platforms (see Figure 35).  The frequency dependence is more pronounced for the Empire State Building results, but less apparent in the Subway data.  Thus, while a system may function well at the lower end of the frequency spectrum in the above ground portions of a large building, the subway results demonstrate that subterranean structures can cause path-loss values greater than 200 dB across the 430 to 2400 MHz range.

NIST TN 1792 - Figure 21: 'Tall Building + System 4 Performance'

NIST TN 1792 – Figure 21: ‘Tall Building + System 4 Performance’. Click to enlarge.

The testing completed here focused on RF PASS system performance and RF propagation-channel measurements in a high-rise and subway station.  While a primary goal of the effort was to look at the correlation between the system performance and path-loss behaviour, a secondary goal was to gather path-loss data in two high-attenuation settings.  Thus, parameter values for log-normal distributions that will allow simulation of the measured path-loss conditions are included in this report.  The authors hope that the data presented here, along with future sets of data, can be used to develop a complete suite of test methods, not only for RF-based PASS systems, but also for other RF-based electronic safety equipment.  The path-loss values obtained here are general and could be used to develop standards for other equipment as the need arises for standards for these systems.
