The International Fraud of Plastics Recycling & E.U. Statistical Reliability ?!?

2024-02-17:  A very recent Report: The Fraud of Plastic Recycling – How Big Oil and the Plastics Industry Deceived the Public for Decades and Caused the Plastic Waste Crisis … published by the Centre for Climate Integrity ( www.climateintegrity,org ), in Washington D.C., #USA … raises serious issues about whether Any Plastic Recycling is technically or economically viable at scale … and serious questions, by implication, about Statistical Reliability in the European Union (#EU) concerning Recycling generally, and Plastics Recycling in particular.

Could this also be the Reason why the Global North is so busy dumping Un-Recyclable Plastics in the previously colonized territories of the Global South ???

.

Short Extract From This Report’s Introduction …

Plastic Pollution is one of the most serious Environmental Crises facing the world today.  Between 1950 and 2015, over 90% of plastics were landfilled, incinerated, or leaked into the environment.  Plastic Waste is ubiquitous – from our rivers, lakes, and oceans to roadways and coastlines.  It is in ‘the air we breathe, the food we eat, and the water we drink’.  One study estimates that humans ingest up to five grams, or the equivalent of one credit card worth of plastic per week.  Some of the largest Oil and Gas Companies are among the 20 petrochemical companies responsible for more than half of all single-use plastics generated globally.  #ExxonMobil, for example, is the world’s top producer of single-use plastic polymers.

Underpinning this Plastic Waste Crisis is a decades-long campaign of #Fraud and #Deception about the #Recyclability of #Plastics.  Despite their long-standing knowledge that recycling plastic is neither technically nor economically viable, petrochemical companies – independently and through their industry trade associations and front groups – have engaged in fraudulent marketing and public education campaigns designed to mislead the public about the viability of plastic recycling as a solution to Plastic Waste.

.

This Report’s Conclusion …

By deceiving consumers, policymakers, and regulators about the viability of Plastic Recycling, petrochemical companies have ensured the continued expansion of plastic production, which has led to a Plastic Waste and Pollution Crisis for communities across the country.  The costs of managing and cleaning up Plastic Waste are largely borne by municipal and state governments – and those costs are projected to increase exponentially in the coming decades, given that Plastic Waste generation in the United States of America is expected to increase from 73 million metric tonnes in 2019 to more than 140 million metric tonnes by 2060.

If not for the Big Oil and the plastic industry’s lies and deception, municipalities and states would not have invested in plastic recycling programmes and facilities – many of which have been shut down due to foreseeable economic losses.  The industry not only misled municipal and state agencies to believe that Plastic Recycling was a viable solution to Plastic Waste but also discouraged them from pursuing other, more Sustainable Waste Management Strategies (e.g., waste reduction, reuse, bans, alternative materials) in favour of plastic recycling.

Fossil fuel and other petrochemical companies should now be held accountable for their deliberate campaign of deception and the resulting harms, much like tobacco and opioid companies that employed a similar playbook.  Based on the growing body of evidence, municipalities and states are likely to pursue litigation, which could put an end to the industry’s deception, make the companies pay for the devastating harms they have caused to communities, and open the door to real solutions that are currently out of reach.

Properly Understanding China’s Uncompromising Assertiveness … Before It’s Too Late !

2023-06-28:  Sustainability is not an abstract concept, divorced from current geo-political realities.  Lasting Peace and Robust International Law are fundamental prerequisites for Sustainable Human and Social Development … a truth forgotten, and/or conveniently set aside, by all parties to the savage and immensely destructive #USA #NATO #EU / #Ukraine / #Russia #War.

USA, 60 Years Ago …

In the tense atmosphere of the Cold War with Russia, and just after the Cuban Missile Crisis a few months earlier … a short extract – inspiring words – from President John F. Kennedy’s Commencement Address at the American University, Washington D.C., on 10 June 1963 …

[ Read and/or listen to #JFK’s Full Speech here: https://www.jfklibrary.org/archives/other-resources/john-f-kennedy-speeches/american-university-19630610 ]

” …  I have, therefore, chosen this time and this place to discuss a topic on which ignorance too often abounds and the truth is too rarely perceived – yet it is the most important topic on earth: World Peace.

What kind of peace do I mean ?  What kind of peace do we seek ?  Not a Pax Americana enforced on the world by American weapons of war.  Not the peace of the grave or the security of the slave.  I am talking about genuine peace, the kind of peace that makes life on earth worth living, the kind that enables men and nations to grow and to hope and to build a better life for their children – not merely peace for Americans but peace for all men and women – not merely peace in our time but peace for all time.

I speak of peace because of the new face of war.  Total war makes no sense in an age when great powers can maintain large and relatively invulnerable nuclear forces and refuse to surrender without resort to those forces.  It makes no sense in an age when a single nuclear weapon contains almost ten times the explosive force delivered by all the allied air forces in the Second World War.  It makes no sense in an age when the deadly poisons produced by a nuclear exchange would be carried by wind and water and soil and seed to the far corners of the globe and to generations yet unborn.

Today the expenditure of billions of dollars every year on weapons acquired for the purpose of making sure we never need to use them is essential to keeping the peace.  But surely the acquisition of such idle stockpiles – which can only destroy and never create – is not the only, much less the most efficient, means of assuring peace.

I speak of peace, therefore, as the necessary rational end of rational men.  I realize that the pursuit of peace is not as dramatic as the pursuit of war – and frequently the words of the pursuer fall on deaf ears.  But we have no more urgent task.  …”

Fast Forward 60 Years To The Present …

The #GroupFeeling towards #China (#PRC) in the same Washington D.C. is an irrational and disturbing mixture of paranoia, panic, fear, jealousy, and war fever.  All too easily, other countries have been sucked into the Hegemonic Agenda of President Joe Biden – an old fashioned, mid-20th Century Cold War Warrior.  Pax Americana, USA #Exceptionalism, weaponisation of the #Dollar, widespread #Sanctioning (at this stage, who isn’t being sanctioned ?), illegal #Trade restrictions, and blatant #HumanRights hypocrisy (see the recent UN Report on the USA #Guantánamo Detention Facility in #Cuba) are all being quietly rejected by the Global ‘South’ and ‘East’.

But who today, in the ‘West’, understands China’s assertiveness … and why it must be uncompromising ?  The #USA’s ideologically-driven ignorance has led, in the past, to enormous blunders … Viet Nam, Iraq, Libya, Afghanistan, etc., etc.

On 25 November 2020, I was very pleased to give a Virtual Presentation to a private discussion group …

Using #Taiwan to bait China and ramp up military tensions can only end badly for the ‘West’.  China’s ‘Century of Humiliation’ is over … President Xi Jinping, and the Communist Party of China (#CPC) Central Committee, will certainly not allow that sad history to repeat itself.

The proposal by NATO (North Atlantic Treaty Organization) to open an office – any type of office – in #Japan is not only ridiculous … it is preposterous.

China is not an enemy of the European Union (#EU) … Ursula von der Leyen (President of the European Commission) and Josep Borrell (High Representative of the European Union for Foreign Affairs and Security Policy) would do well to remember that !

[ Footnote 1: Use of Cluster Munitions in Armed Conflicts …

The Convention on Cluster Munitions (https://www.clusterconvention.org/) – adopted in Dublin on 30 May 2008, and became binding #InternationalLaw when it entered into force on 1 August 2010 – was born out of a collective determination to address the humanitarian consequences and unacceptable harm to civilians caused by cluster munitions.  States Parties to the Convention are committed to the full universalization of the #CCM and to promote its norms, as well as to fully implement it.  Its implementation contributes to advancing the achievement of the UN Sustainable Development Goals (#SDG’s) and the promotion of International #Peace and #Security, #HumanRights and International Humanitarian #Law.

Noel Manning – Innovative Fire Researcher !

2019-03-18:  Lest we forget him …

Long before the Rest of the World was introduced to the term Fire-Induced Progressive Damage, in the late afternoon of 11 September 2001 (WTC 9-11), with the collapse of World Trade Center Building No.7 in New York City …

(9-11) WTC Building No.7 – Fire-Induced Progressive Damage !

… decades earlier … Noel Manning had intuitively discovered the same Structural Fire Engineering Concept … and had developed and tested a suite of domestic-scale building systems to deal with this very dynamic aspect of fire behaviour …

Noel C Manning – 2017-11-05 RIP

.

The International Fire Engineering Community is still shy about discussing this concept, never mind understanding it … and most importantly, solving it !   Which makes me seriously wonder … is there a deep-seated flaw in International Fire Research ?   Are mainstream Fire Researchers more interested in sourcing funding than in actually solving ‘real’ world fire engineering problems ???

And I also wonder … why have the 2005 and 2008 NIST (USA) WTC 9-11 Recommendations on the WTC Building Collapses still not been properly implemented within the USA … and why have they been ignored everywhere else ?????

England’s 2017 Grenfell Tower Fire – Never Again Elsewhere ??

2018-06-12 …

As we approach the First Anniversary of the Grenfell Tower Fire Tragedy, in England, on 14 June … a few days ago, on 4 June 2018, the first batch of Grenfell Expert Witness Reports were uploaded (https://www.bbc.com/news/uk-44356660) to the Grenfell Tower Inquiry Website (https://www.grenfelltowerinquiry.org.uk/) for public view.

At this time, in London … multiple, fragmented investigations are taking place into the actual fire incident … the role of the Local Authority, and building management … those involved in the refurbishment (‘tarting up’) design and construction … the fire services, particularly their ‘Stay Put’ Policy and how it adversely impacted on vulnerable Tower occupants during the emergency … and the highly flawed regulatory model of Building and Fire Codes with light-touch Control, which is still operating in England.  One of Murphy’s Laws immediately springs to mind with regard to the intended ineffectiveness of this overly-complex process !

Colour photograph showing Grenfell Tower in the background … undergoing an almost complete ‘cover-up’ … with, in the foreground, mementos of the Fire Tragedy fixed to railings by local residents. Click to enlarge. Photograph taken by CJ Walsh. 2018-04-29.

Many other countries have adopted some or all of this modern English regulatory model which, after the repeal of an older Bye-Law format, has been shaped by political expediency, cost-effectiveness and general ineptitude … with little or no adaptation to local conditions in the adopting jurisdictions.  Ireland adopted this model with some, but not a lot, of adaptation.

Fire Safety In Ireland ?

On 6 June 2018 … while that investigative activity was hitting the headlines in England … Minister Eoghan Murphy, T.D., Ireland’s Minister for Housing, Planning and Local Government, quietly published the Report: ‘Fire Safety in Ireland’http://www.housing.gov.ie/local-government/fire-and-emergency-management/fire-safety/eoghan-murphy-publishes-report-fire … by a High-Level Task Force within his Department’s National Directorate for Fire and Emergency Management, after serious concerns and fears had been expressed in the public media that a similar fire tragedy might also occur in this jurisdiction.

To be crystal clear … this Report is a Bureaucratic Whitewash … an insult to the Public !  Nice sounding technical ‘blarney’ camouflages a failure to deal directly with critical issues, and answer concerns … while other important issues are avoided altogether.

May 2018 – Ireland’s Department of Housing, Planning & Local Government Report

Fire Safety In Ireland  (PDF File, 2.55 MB)

Expanding on my comments in the Interview with Barry Lenihan, on RTE Radio 1’s Drive Time early evening news programme on Friday (2018-06-08) …

A.  Initially, Irish Local Authorities were requested to carry out a preliminary survey to identify all buildings of more than six storeys, or 18m in height.  Specifically, they were asked to identify those buildings which had an external cladding system which might be a cause for concern.

This height threshold of six storeys/18m is arbitrary … an external cladding system can be just as much a cause for concern in a building which is lower.  Imagine discarded cigarette butts or a rubbish fire at the base of such a system … and the resulting speed of fire spread and development across a building façade !

B.  The highly flawed regulatory model of Building and Fire Codes, with light-touch Control, which resulted in the Grenfell Tower Fire Tragedy … we also have.  Wake up and smell the coffee Ireland !

At the beginning of the 1990’s, when Ireland had been persuaded by the European Commission to finally introduce legal, national building regulations having a functional format … our National Authority Having Jurisdiction, in desperation, grabbed the then Approved Documents for England & Wales … brought them back to Ireland, put Irish covers on them, and originally called them ‘Technical Documents’ … but, after seeing a tiny ray of inspiring light, later changed their title to the more accurate ‘Technical Guidance Documents’ !  This hunger for adopting all things English which are fire safety related continues to this day … with a similar, ongoing division of Technical Guidance Document B: ‘Fire Safety’ into 2 Separate Volumes.

This may have been a convenient response under pressure … but it has been very short-sighted.  It has impeded the growth of a comprehensive and coherent philosophy on Safe, Inclusive, Age-Friendly, Resilient, Sustainable Planning, Design and Construction Codes/Controls which is suited to an Irish context and responsible local needs (not desires!).

C.  Everywhere … this Report has a lot – too much – to say about Fire Risk Assessment !  After the Grenfell Tower Fire, however, Fire Risk Assessments must only be carried out by competent persons … and the process of Fire Risk Assessment, itself, must be radically improved !  And of course, prior to any Risk Assessment … a proper Fire Hazard Appraisal must be carried out.

D.  To accurately present Fire Safety Trends in Ireland … it is not enough to furnish reliable fire fatality statistics.  It is also necessary to produce reliable fire injury statistics … and reliable information on direct/indirect socio-economic losses.

E.  The quality of fire safety related construction on Irish Building Sites continues to be very poor and problematic.  Fire Compartmentation is nowhere near being adequately – never mind acceptably – reliable !  And during the last few years we have had quite a number of close-calls concerning fire incidents in medium-rise residential buildings.

F.  Fire Evacuation for people with activity limitations is still handled atrociously in our current building regulations.  This is ironic because, on 20 March 2018 last, Ireland had to be dragged screaming to ratify the U.N. 2006 Convention on the Rights of Persons with Disabilities (CRPD) !

.

Positive Progress By Another Path !

1.  Abandon the outdated English functional requirements in THEIR building regulations … and adopt a far better, more up-to-date body of functional requirements which is already on the Irish Statute Books … Annex I of the European Union’s Construction Products Regulation 305/2011.  And because there are important horizontal linkages between requirements … immediately finish the ridiculous current separation between Fire Safety requirements and all of the other requirements.  And yes … new Technical Guidance Documents will have to be drafted.

.Regulation (EU) No 305/2011 of the European Parliament and of the Council, of 9 March 2011, laying down harmonized conditions for the marketing of construction products and repealing Council Directive 89/106/EEC

EU Regulation 305/2011 – Construction Products.  See Annex I

(PDF File, 998 Kb)

2.  Yes … ‘Persons Having Control’ of buildings have responsibilities with regard to fire safety.  But that is only one side of the coin !  National and Local Authorities Having Jurisdiction have greater responsibilities.

If we are at all serious about Consumer Protection … bad, inadequate, faulty construction must be prevented beforehand … it is too late, too costly and, in many cases, too impractical to correct afterwards.  Self Regulation by building design professions and construction organizations is NO Regulation !  Stringent, independent technical control inspections must be carried out on all projects by Building Control personnel … which used to happen in Dublin City/County and Cork City/County prior to the introduction of legal building regulations in the early 1990’s … and, depending on complexity, must also be carried out at critical stages during the construction process.

Building Control Sections in all Local Authorities must be properly resourced with competent personnel, equipment, training and support infrastructure.

Inspections concerning compliance with all functional requirements in the building regulations, including fire safety, must be carried out only by Building Control Personnel.  Chief Fire Officers must not be allowed to manage or be involved in any aspect of Building Control.  On the same project … a Disability Access Certificate Application and a Fire Safety Certificate Application must be inter-linked and overlap sufficiently, showing no gaps in compliance.  Inspections must be carried out in connection with all Certificate Applications.  Building Control personnel must satisfy themselves that actual construction at least matches, if not improves upon, what is shown in design documentation.

Building Control Inspection Reports must be made available for public view.

3.  Firefighters are NOT a disposable Social Asset !  National and Local Authorities Having Jurisdiction … and some Chief Fire Officers … must begin to understand this fundamental truth !

Fire Services in all Local Authorities must each be properly resourced according to local needs … with competent personnel, equipment, training and support infrastructure.  Shared provision of resources looks very neat on paper but, in practice, works very badly.  Refer to the Grenfell Tower Fire and London Fire Brigade having to borrow firefighting equipment from other Fire Services.

After the 2015 Tianjin Regional Fire Devastation, in China, and the 2001 WTC Attacks on 9-11, in New York City … front line firefighters must be supported by Specialist Hazard Appraisal and Structural Engineering Units.

For Firefighter Safety in buildings and to quickly find people with activity limitations waiting in Areas of Rescue Assistance and/or other survivors in different locations … a portable and reliable Thermal Imaging Camera is an essential piece of every firefighter’s equipment.

And Firefighter Safety begins with good building design.  In all but the most simple building types, Circulation Routes must be designed for Contraflow … people moving away from a fire in a building and towards safety while, at the same time, heavily equipped firefighters are entering the building and moving towards the fire.

Colour photograph showing Contraflow on a building staircase … people moving down a staircase away from a fire and towards safety while, at the same time, heavily equipped firefighters are moving up the staircase towards the fire. Click to enlarge.

There is no place for ‘Stay Put’ Policies in Irish Residential Buildings of any height.

After The Grenfell Tower Fire !

Further to my last Blog, dated 2017-10-10 …

The 2017 Fire in England was not an extraordinary fire.  Since the beginning of this decade, we continue to see a series of such fires: South Korea (2010) – UAE & France (2012) – Chechnya (2013) -Australia (2014) – UAE, Azerbaijan & UAE again (2015) – UAE (2016) – UAE & Russia (2017) – Turkey (2018).

With regard to Command & Control of Large Scale Emergencies … English AHJ’s should have paid attention to the 2005 & 2008 U.S. National Institute of Science & Technology (NIST) Recommendations following the 9-11 WTC Buildings 1, 2 & 7 Collapses.

The Fire Safety Objectives in current Building & Fire Codes/Regulations are very limited.  In Ireland, this is clearly stated in Technical Guidance Document B …

‘ Building Regulations are made for specific purposes.  Part B of the Second Schedule to the Building Regulations is therefore primarily concerned with the health, safety and welfare of persons.  The fire safety measures outlined in this guidance document are intended for the protection of life from fire.’

Only insofar as it is necessary to protect the lives of able-bodied building users/occupants … is there a concern for property protection.

There is only inadequate, token concern for the protection of people with disabilities.

Client organizations, facility managers, building designers, construction organizations … and journalists … must fully comprehend these limits.

In the photograph below … look closely at the External Firefighting Operations at the bottom of the Tower.  There are limits to what can be achieved from outside a building !

Colour photograph showing the developed fire at Grenfell Tower, in London. At the bottom of the Tower, external firefighting operations can be viewed. Click to enlarge.

.

  • A Fire Suppression System (Water Sprinklers/Mist/Hybrid) is an essential Fire Protection Measure in ALL Medium and High-Rise Residential Buildings … which include Apartment Blocks, Hotels, Hostels, Student Accommodation & Social Housing, i.e. ANYWHERE there is a Sleeping Hazard.

 

  • A Reliable and Credible Fire Detection & Warning System is an essential Fire Protection Measure in ALL Buildings … and must be capable, under the control of Building Management, of transmitting warnings in many formats, i.e. Audible + Visual + Multi-Lingual Voice + Tactile.

 

  • Fire Evacuation Routes in Buildings must be designed for CONTRAFLOW … people moving away from a fire and towards safety while, at the same time, heavily equipped firefighters are entering the building and moving towards the fire.

 

  • Good Fire Evacuation Route Design is INTUITIVE and OBVIOUS.  In many buildings, however, this is not always the reality.  Effective Fire Evacuation Signage … comprising high-level signage, low-level signage, with both supplemented by photoluminescence … must be installed in ALL Buildings.

 

  • For the purpose of protecting Vulnerable Building Users in Fire Emergencies, ALL Lifts/Elevators in Buildings must be capable of being used for Evacuation.

 

  • Fire Risk Assessments must NO LONGER be carried out by people WITHOUT COMPETENCE in Fire Engineering AND Building Design & Construction … and the Fire Risk Assessment Process itself must be thoroughly re-examined and upgraded.

CUBA: Still a Target for Ill-Informed Media Opinion & Hysteria !?!

2017-02-21:  The day after the death of Fidel Castro Ruz, Revolutionary Leader and Former President of Cuba … Michael D. Higgins, President of Ireland, issued a News Release on 26 November 2016, which can be viewed here … http://www.president.ie/en/media-library/news-releases/P24

Media reaction, in Ireland, to this News Release was hysterical and grossly ill-informed !

“A revolution is not a dinner party, or writing an essay, or painting a picture, or doing embroidery ;  it cannot be so refined, so leisurely and gentle, so temperate, kind, courteous, restrained and magnanimous.  A revolution is an insurrection, an act of violence by which one class overthrows another.”

Wonderful Chinese Garden of Friendship in Sydney, Australia

2016-12-21:  Just as President-Elect Humpty Trumpy is turning up the pressure on China … (and IF there is a serious incident between these two countries, the USA will automatically assume that it will have the unconditional and unquestioning support of a select little band of ‘groupie’ allies, each claiming to have a special and unique relationship with it !) … let me to bring to your attention the wonderful Chinese Garden of Friendship, located near Darling Harbour, in the city of Sydney … a symbol of friendship between the people of Guangzhou, capital city of the province of Guangdong in south-eastern China (Peoples’ Republic of China), and the people of Sydney, in New South Wales – two sister cities of sister states.

Firefighter Safety & Solar Photovoltaic Panels On Buildings ??

2016-09-14:  Only now are we really catching up with the extremely serious matter of Fire Safety in Sustainable Buildings … serious for building occupants … and firefighters !

‘ In order to achieve sustainable development, environmental protection and energy efficiency/conservation shall constitute integral parts of the development process, and shall not be considered in isolation.’

2016 Dublin Code of Ethics: Design, Engineering, Construction & Operation of a Safe, Resilient & Sustainable Built Environment for All   ( www.sfe-fire.eu )

The Performance Target for New Construction must be Positive Energy Buildings.

So … we will see more and more Solar Photovoltaic Panels installed on more and more buildings … in every country.  Certainly not less !   And, let’s face it, many will not be properly approved, i.e. shown to be ‘fit for their intended use’ …

At the beginning of this decade, a Fire Research Project was carried out by the Underwriters Laboratories Firefighter Research Institute in the USA … and it addressed the issue of firefighter vulnerability to electrical hazards, and serious injury, when fighting a fire involving Solar Photovoltaic (PV) Modules and Support Systems installed on buildings.

The Total Global Solar Energy Capacity averaged 40 % annual growth from 2000 to 2010 (source: International Energy Agency).  In the USA, Grid-Connected Solar Photovoltaic Capacity grew 50 % per year for much of that time (source: US Federal Energy Regulatory Commission).  These trends increase the potential of a Fire Service Response to a building having a Photovoltaic Installation, irrespective of the PV being involved with the initiation of the fire event.  As a result, conventional firefighter tactics for suppression, ventilation and overhaul have been complicated, leaving firefighters vulnerable to potentially unrecognized exposure.  Though the electrical and fire hazards associated with electrical generation and distribution systems are well known, PV Systems present unique safety concerns.  A limited body of knowledge and insufficient data exist to understand these risks … to the extent that Fire Services have been unable to develop safety solutions and respond in a safe manner.

This Fire Research Project developed the empirical data needed to quantify the hazards associated with PV Installations … and provided the foundation to modify current or develop new firefighting practices to reduce firefighter deaths and injury.

The Tactical Considerations addressed during the Project include:

  • Shock hazard due to the presence of water and PV power during fire suppression activities ;
  • Shock hazard due to the direct contact with energized components during firefighting operations ;
  • Emergency disconnect and disruption techniques ;
  • Severing of conductors ;
  • Assessment of PV power during low ambient light, artificial light and light from a fire ;
  • Assessment of potential shock hazard from damaged PV Modules and Systems.

UL Report (2011):  The Following Summarizes the Findings of This Fire Research Project:

  1. The electric shock hazard due to the application of water is dependent on voltage, water conductivity, distance and spray pattern.  A slight adjustment from a solid fire hose stream towards a fog pattern (10 degree cone angle) reduced measured current below perception level.  Salt water should not be used on live electrical equipment.  A distance of 6 m has been determined to reduce potential shock hazard from a 1000 VDC source to a level below 2 mA, considered as safe.  It should be noted that pooled water or foam may become energized due to damage in the PV System.
  1. Outdoor weather exposure-rated electrical enclosures are not resistant to water penetration by fire hose streams.  A typical enclosure will collect water and present an electrical hazard.
  1. Firefighters’ gloves and boots afford limited protection against electrical shock provided the insulating surface is intact and dry.  They should not be considered equivalent to Electrical Personal Protective Equipment (PPE).
  1. Turning off an array is not as simple as opening a disconnect switch.  Depending on the individual system, there may be multiple circuits wired together to a common point such as a combiner box.  All circuits supplying power to this point must be interrupted to partially de-energize the system.  As long as the array is illuminated, parts of the system will remain energized.  Unlike a typical electrical or gas utility … on a PV Array, there is no single point of disconnect.
  1. Tarps offer varying degrees of effectiveness to interrupt the generation of power from a PV Array, independent of cost.  Heavy, densely woven fabric and dark plastic films reduce the power from PV to nearly zero.  As a general guide, if light can be seen through a tarp, it should not be used.  Caution should be exercised during the deployment of tarps on damaged equipment, as a wet tarp may become energized and conduct hazardous current if it contacts live equipment.  Also, firefighting foam should not be relied upon to block light.
  1. When illuminated by artificial light sources, such as Fire Department light trucks or an exposure fire, PV Systems are capable of producing electrical power sufficient to cause a lock-on hazard.
  1. Severely damaged PV Arrays are capable of producing hazardous conditions ranging from perception to electrocution.  Damage to the array may result in the creation of new and unexpected circuit paths.  These paths may include both array components (module frame, mounting racks, conduits, etc) and building components (metal roofs, flashings and gutters).  Care must be exercised during all operations, both interior and exterior.  Contacting a local professional PV Installation Company should be considered to mitigate potential hazards.
  1. Damage to modules from tools may result in both electrical and fire hazards.  The hazard may occur at the point of damage or at other locations depending on the electrical path. Metal roofs present unique challenges in that the surface is conductive unlike other types such as shingle, ballasted or single ply.
  1. Severing of conductors in both metal and plastic conduit results in electrical and fire hazards.  Care must be exercised during ventilation and overhaul.
  1. Responding personnel must stay away from the roofline in the event of modules or sections of an array sliding off the roof.
  1. Fires under an array but above the roof may breach roofing materials and decking … allowing fire to propagate into the attic space of the building.
