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 !

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.

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

This was a good effort by our public representatives … but they missed core issues !


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.”

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’ …

Colour photograph showing a house fire caused by Solar Photovoltaic Roof Panels.
Colour photograph showing a house fire caused by Solar Photovoltaic Roof Panels.

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.

Colour photograph showing two firefighters on a roof, one with cutting equipment. Solar Photovoltaic Roof Panels restrict firefighter access to building interior roof spaces.
Colour photograph showing two firefighters on a roof, one with cutting equipment. Solar Photovoltaic Roof Panels restrict firefighter access to building interior roof spaces.

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.


Office of California’s State Fire Marshal – November 2010

Fire Operations for Photovoltaic Emergencies (CAL FIRE – 2010)  (PDF File, 1.99MB)


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.




U.S. Implementation of NIST’s 9-11 WTC Recommendations ?!?!

2016-05-05:  A Mickey Mouse Effort would be a polite way of describing the long drawn-out and tortuous process of implementing NIST’s Recommendations in the United States.  A better description might be … FUBAR !

15 Years After the 2001 WTC 9-11 Attacks in New York City … absolutely nothing has been done concerning the implementation of a significant number of Recommendations … other Recommendations have been only partially implemented, with many being limited to application in buildings over 128m high (420 feet in ye olde silly imperial units of measure), or else buildings over 22.86m high (75 feet) which have an occupant load exceeding 5,000 people or are essential facilities, e.g. hospitals.  And believe it or not, some implementing measures are still being challenged and they may yet be reversed in the years ahead.  Forget about discussing the already narrow Fire Safety Objectives in building codes/regulations, or Protecting Society, etc., etc.  In essence, it has all come down to that ‘durty’ four letter word: COST !

But read this 2011 Status Report for yourselves.  I have kept in touch with the current situation over there.

NIST’s WTC 9-11 Recommendations Status Report (2011-08-08) – PDF File, 330 Kb

Why should this matter ?

In 2005 & 2008, the U.S. National Institute of Standards & Technology issued a series of very important [ critical ] Recommendations on badly needed revisions to the Design – Construction – Management – Firefighting Procedures for Very High/Tall Buildings, High-Risk Buildings, Iconic Buildings, and Innovatively Designed Buildings.  Many, if not all, of these Recommendations were, and remain, just as valid and just as necessary in the case of other building types … whatever their height.

A lot of effort was expended here, a few years ago, on a detailed examination of the NIST Recommendations.  In one respect, the Recommendations have become dated and obsolete.  The recent 2016 Brussels and 2015 Paris Hive Attacks have altered how we must categorize and deal with buildings of ‘high-risk’.  From the start, however, the disability-related Recommendations only concerned mobility impaired building occupants … a serious flaw.

NIST does not have the legal authority to implement its own Recommendations within the United States.  However, implementation by the Model Code (e.g. IBC & NFPA) Organizations has been brutally slow and entirely inadequate.

And … it is very noticeable how so many other countries around the world are continuing  to completely ignore NIST’s Recommendations.  9-11 never happened !




LEED, PassivHaus & BREEAM Housing ~ Atrocious Fire Safety !!

2016-04-11:  It Happened One Night !

And Maybe … if it hadn’t been that particular night, during all the festivities of New Year’s Eve 2015, we would never have heard about the Address Supertall Hotel Fire, in Dubayy (UAE).  A long search on the Internet afterwards led to the detailed, post fire analysis report on the 2014 Lacrosse Docklands Fire, in Melbourne (Australia) … followed by some more searching, and a very large can of worms opened up … similar nasty façade (external fabric) fires in many, many countries … involving large chunks of flaming debris falling from terrific heights, carried by the wind to a significant distance away from the building of fire origin.

Some people have tried to suggest that the only reason for these fires is inadequate building codes/regulations.  No … the reason for these fires is much more than that … it’s the ‘SYSTEM’ !   In other words, how the International Construction Sector is organized and goes about its ordinary, everyday activities and tasks.  We must also talk about poor quality design and construction … and a lack of stringent, independent enforcement of effective building codes/regulations and standards.  I have written this down many times before … Self-Regulation is NO Regulation !!

It is very clear that Conventional Fire Engineering … as currently practiced, internationally … is no longer ‘fit for purpose’.  For discussion at SFE 2016 DUBLIN.  Check out the Fire Conference Website: www.sfe-fire.eu … and on Twitter: @sfe2016dublin

[ Fast forward from 2011 … overtaking Priory Hall (see my series of Blogs) … to Longboat Quay, a large residential development on the south bank of the River Liffey, which flows through the middle of Dublin.  A recent visual/surface inspection of one of the units there revealed not just a poor quality of construction … but a lack of care and attention, with a mixture of incompetence and ignorance thrown in for good measure.]

The 2015 Terraced Housing Fire, shown above, should not have been a surprise to the ‘System’ in Ireland.  Research carried out in the U.S.A., Belgium and The Netherlands since 2012, and a serious PassivHaus Apartment Fire in Köln, Germany, on the night of 5 February 2013  … have all shown that the modern home (highly insulated, airtight, packed with electronic equipment and wiring, and fast-burning synthetic furnishings, etc.) is the ‘perfect storm’ of fire conditions and outcomes.  More open residential design + increased fuel loads + new construction systems and materials = faster development of fires, much reduced times to flashover, far less time for occupant evacuation, particularly people with activity limitations … and shorter building collapse times.

The time to flashover in modern high-performance housing, i.e. Sustainable/Green/PassivHaus/Eco/LEED/Bio/+Energy/Low Carbon/BREEAM/Zero Carbon/SMART … can be 7 times faster than in conventional/legacy housing … or less than 5 minutes, compared with just over 29 minutes !

All of this research can be found on the Links & Docs Page of the SFE 2016 DUBLIN Website.

Let us be crystal clear … there is nothing Sustainable/Green/PassivHaus/Eco/LEED/Bio/+Energy/Low Carbon/BREEAM/Zero Carbon/SMART about the post-fire scenes of destruction shown above.  And only for the physical separation between terraces, which can be clearly seen in the last photograph … the fire would have kept spreading.



Without a balanced, proper approach to the issue of Fire Safety in this type of modern, high-performance housing … occupant safety is seriously threatened.  And if, in the event of a fire incident, the occupants are asleep … or people with activity limitations are living in the house … that threat will be extremely grave indeed.

Reality – Reliability – Redundancy – Resilience !

So … what needs to change ?   In Ireland, our immediate problem is Timber-Framed Housing (as shown above) … and the following is an outline of what must change … NOW !

  1. Party Walls, i.e. the walls separating one house from another, must be constructed of solid masonry, with a uniform and uncompromised thickness of at least 200mm … plastered on both sides, not dry-lined, for adequate smoke resistance … and be continued above the roof covering for at least 300mm.
  2. An effective Fire Detection System must be installed.  The conventional ‘package’ of one smoke detector per floor in the hallway and staircase of a standard 2 storey semi-detached house is nowhere near being adequate.
  3. An effective Residential / Domestic Fire Suppression System must be installed, e.g. low pressure water mist.  See later post, dated 2016-06-13, for a costed notional installation.
  4. If there is a Controlled Ventilation System, either mechanical or natural, in the house (for the purposes of air quality, heat exchange and energy conservation), it must be linked to the fire detection system.  In the event of a fire incident, the Ventilation System must immediately cease operation, and remain ‘fully open’.  This is in order to mitigate the build-up of high positive pressure, within a confined airtight space, caused by a developing fire … and to provide an exhaust route for smoke and toxic gases … during the short period of time prior to activation of the fire suppression system.
  5. Intermediate Timber Floors and Evacuation Routes, including fire resisting doorsets, must be reliably protected from fire and smoke.  The minimum period of fire and smoke resistance must be linked to local fire service support infrastructure.  In other words, the local fire services must be allowed sufficient time to arrive at the scene of a fire in strength … to search for any occupants still remaining in the fire building … and to bring the fire under control.
  6. Uppermost Ceilings under a trussed timber roof structure, including any trap doorsets into the roof space, must be similarly and reliably protected from fire and smoke.  Once fire enters a roof space, the light trussed timber structure will collapse within a few minutes.
  7. Front and Back Entrance/Egress Doors must be outward opening.  In the 2013 German PassivHaus Apartment Fire, the occupant found it extremely difficult to open inward opening doors and windows because of the high positive pressure caused by the developing fire.  This unusual phenomenon was confirmed in the 2015 Finnish Apartment Fire Tests, when much higher positive pressures were observed.
  8. Internal Linings of External Walls must comprise 2 layers of plasterboard, with all joints staggered … steel fixed, at not more than 150mm centres.  Once fire breaches the internal lining of an external wall, the whole building will become involved in the fire.  Horizontal and vertical fire sealing behind these linings, even if properly installed (!), are too little and too late.
  9. Frontline Firefighters must be supported by specialist structural engineering and hazard appraisal units … and light/portable/reliable Thermal Imaging Cameras must be recognized as a standard tool of firefighting.



These building types are more popularly known as Green, PassivHaus / Passive House, LEED, Eco, Bio, BREEAM, +Energy, Zero / Low / Nearly Zero Carbon, or SMART, etc., etc, etc.   In ALL of these cases, however, an Effective Residential Fire Suppression System MUST BE INSTALLED, e.g. low pressure water mist !

In everyday practice … Authorities Having Jurisdiction (AHJ’s), and the Organizations and Individuals responsible for the far-too-rapid construction of these innovative building types are either completely and blissfully ignorant, or callously and negligently in denial, about the seriously negative impacts on Occupant & Firefighter Fire Safety and Building Fire Protection.

BUT … slowly … more and more reliable evidence is being gathered !   Please visit the Links & Docs Page on: www.sfe-fire.eu … and also view this Presentation on some very interesting 2015 Apartment Fire Tests in Finland: www.youtube.com/watch?v=0Ss_ONolzLY



In refurbishment projects where insulation is fixed to the internal surfaces of external walls … similar fire safety problems exist, and they must be solved by reviewing the full checklist above.  Refer again to the PassivHaus Apartment Fire in Köln, Germany, on the night of 5 February 2013 … and to the 2015 Apartment Fire Tests in Finland




Open E-Mail to ISO TC 92 (Fire Safety) – Treatment of ‘Disability’

2014-11-05:  ISO TC 92: ‘Fire Safety’ is a long-established Technical Committee within the International Standards Organization (ISO) …  www.iso.org/iso/home/standards_development/list_of_iso_technical_committees/iso_technical_committee.htm?commid=50492  … and down through the many years of its existence, since 1958, it has laboriously constructed a robust foundation which has facilitated the modern evolution of Fire Science and Engineering and the development of many standard fire safety practices and procedures around the world.

BUT …  and in spite the existence of ISO/IEC Guide 71: ‘Guidelines for Standards Developers to Address the Needs of Older Persons and Persons with Disabilities’ (a weak document which is badly in need of revision and updating !)

Recently, having examined some draft standards being processed through ISO TC 92 … I have become very tired of the blatant incompetence … and lack of care and concern merging with feigned ignorance and/or stubborn resistance, within the Technical Committee, when it comes to the issue of ‘disability’ … in other words, the major matter of the real fire safety of vulnerable building users and occupants, i.e. people with activity limitations, in real buildings.

SO …  a few days ago, I wrote the following e-mail message to a Working Group Chairperson (who shall remain nameless, because this same problem pervades the whole TC) …


Dear X,

With regard to All Aspects of the WG’s Work … one issue, in particular, sticks out like a sore thumb … how you treat ‘disability’.  There is no clarity here, only confusion.  There are no precise terms, only a garbled use of language and concepts.

Please allow me to suggest, with accompanying explanations, a suitable and necessary path forward.

I will circulate this e-mail message separately within ISO, and beyond.

Concerning Normative References … reference must be made to …

ISO 21542 (2011): ‘Building Construction – Accessibility & Usability of the Built Environment’

Within this document, Accessibility is understood to mean the full cycle of independent building use, in an equitable and dignified manner … and to include 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.

Texts relating to ‘fire safety’ have been incorporated into the main body of this International Standard.  It is, however, just a small beginning.  Much work remains to be done.

Accessibility Design Criteria, as described in ISO 21542, must now be applied to the design and maintenance of all fire evacuation routes, fire safety related signage and fittings, etc., etc.

Use of the word escape, in any context, is strongly discouraged.

Concerning Terms & Definitions

People with Activity Limitations:  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.

Attached, please find the FireOx International ‘Fire Safety for All’ Matrix … which illustrates how the separate pieces, including ‘disability’, fit together.

Contraflow:  Emergency access by firefighters or rescue teams into a building and towards a fire, while people are still moving away from the fire and evacuating the building.

Concerning Building User/Occupant Numbers & Provision … ‘token’ is not only entirely unacceptable, it is a clear case of professional negligence …

And why, suddenly, all of these ‘musts’ ??

Cogently mandated in the United Nations Convention on the Rights of Persons with Disabilities (CRPD) … the UN 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 set down in the Universal Declaration of Human Rights (1948).

The language of the Convention is always very robust and very direct: ‘States Parties shall …’

Also attached, please find a United Nations Global Map showing the status of Convention Ratification back in July 2014.  At the time of writing this e-mail message, 151 Countries have ratified the UN CRPD.

Full and Effective Accessibility of the Built Environment is a human right.  Adequate provision must be made for people with disabilities to use all buildings … not just some buildings … and certainly not just limited parts of a building !

In practice, people with disabilities must be included in all practice evacuation drills … and they must be included in all activities related to ‘fire safety’ and/or necessary to prepare for safe evacuation.

Furthermore … because Electronic, Information and Communication Technologies (EICT’s) now serve a function which is critical, during a fire incident, for the safety of all building users and firefighters, property protection, minimizing environmental damage, and sustainability … they must have a user interface which is Accessible for All … from both ends.

With regard to ‘adequate’ provision … please find attached the 2010 USA Disability Statistics … which indicate:

  • Minimum Reasonable Provision for People with Disabilities in a Building … 10% of User/Occupant Population ;
  • Minimum Reasonable Provision for People with Activity Limitations in a Building … 15% of User/Occupant Population.

The numbers of people with disabilities in developing and the least developed economies far exceed numbers in developed economies !

Best wishes for the success of your meeting in Sydney.
