Ar C.J. Walsh – Consultant Architect, Fire Engineer & Technical Controller – International Expert on : Sustainability Implementation + Accessibility (including Fire Safety) for All + Sustainable Fire Engineering
Sustainable Fire Engineering (SFE) is a Facilitator – no more than Architecture, Structural Engineering, or Spatial Planning – in the task of realizing a Safe, Resilient and Sustainable Built Environment for All. However, SFE has an essential role to fill throughout the difficult journey towards that target. In close collaboration with other design disciplines, many iterations … twists and turns along the road … will be necessary.
Beware Greenwashing !
Sustainability is NOT a graft-on, or an optional extra, to Conventional Fire Engineering. This intricate, open, dynamic and continuously evolving Concept must cut right to the core of everyday design practice, and must positively impact all areas of that practice.
In this third decade of the 21st Century … the Safety Objectives in current Fire Codes / Regulations are limited, inadequate, and lagging far behind today’s creative moulding and re-shaping of the Built Environment ; they are almost, but not entirely, irrelevant in the context of the urgently required transformation of conventional fire engineering. For anybody who cannot see the broad, beautiful landscape beyond codes and regulations … this SFE Road Map is definitely not for you. For those who can see, your constant companion … your compass … will be a Personal Code of Ethics.
Essential Considerations Before Starting Out On The Road …
1.World Trade Centre Attacks in New York City, on 11 September 2001. Two sets of important Recommendations were issued by the U.S. National Institute of Standards and Technology (NIST) in 2005 and 2008. Not only is the implementation of these still incomplete, but the solid progress which has been made e.g. on Firefighter Safety, is continuously under threat from vested interests. Other jurisdictions have tended to ignore the Recommendations. SFE takes full account of this Extreme Man-Made Event.
2.Grenfell Tower Fire in London, on 14 June 2017. Evidence at the Official Inquiry continues to shock and horrify ; the entire fire safety regulatory edifice in England is dysfunctional, and it poses a real and serious danger to Public Health and Safety. Inquiry Phase 1 Recommendations were issued in 2019. Already, the Recommendation concerning Evacuation for Vulnerable Building Users & PEEP’s (#33.22 e and f) has been discarded by AHJ’s … and it has also been stated (#34.14) that as everything about the single narrow staircase in the Tower appeared to be OK, it will not be investigated in Inquiry Phase 2 … a sure sign of dysfunctional dysfunction ! SFE sees beyond these major flaws.
3.Sustainable Buildings Il Bosco Verticale Towers in Milano … this exciting Project, designed by Stefano Boeri and completed in October 2014, has become the International Icon for innovative / environment-friendly construction. These new approaches to building design are posing enormous fire safety challenges. [ Remember back … was it 15 years before fire codes were able to ‘solve’ the Atrium in buildings ? ] SFE, however, must cope with this extraordinary level of architectural creativity ; and Fire Engineering Practitioners must be capable of active participation, collaboratively, within Project Design/Construction Teams.
Looking past the Milan Project … it is important for the reader to experience a more rounded flavour of where the exciting synergy between Creative Design and the Inclusive Language of Sustainability is at present, and where it is tending to go …
4.Building Energy Performance Rating Schemes Under enormous environmental and political pressures, the headlong rush to conserve energy in buildings, and to make them more energy efficient … especially after the 2022 Russian Invasion of Ukraine … is proceeding in blissful ignorance of fire safety and necessary independent technical controls. Measurement of real building performance, after energy refurbishment has been completed, is generally avoided.
The Road Ahead … From Gro Harlem Brundtland To Reliable Fire Statistics …
2020-09-08: Ignoring Britain’s silly sabre-rattling, toothless threats and boorish blackmail attempts reported in the Media during this past weekend, yesterday and today … the actual state of play in the tortuous Brexit Negotiations can best be judged from the following sources …
Michel Barnier’s Presentation to the Institute for International and European Affairs (IIEA), on 2 September 2020 … View it Here on YouTube
This is the European Union (EU), a Single Market of approximately 450 Million consumers. The EU operates under the freedoms and protections of Codified / Written Law, i.e. EU Treaties ratified by all of the EU Member States, EU Secondary Legislation (Regulations and Directives), and EU Administrative Provisions.
A suite of EU Regulations and Directives covers Industrial Products. While there is some flexibility with regard to how Directives are implemented at national level in the Member States, no such flexibility exists with Regulations. Construction Products can only be placed on the EU Single Market if they can be shown to comply with the requirements of the EU’s Construction Products Regulation (CPR) Framework, or in other words, be shown to be ‘fit for their intended use’ in the European Union …
BREXIT ~ IMPLICATIONS FOR THE BRITISH FIRE INDUSTRY
Trade ‘No Deal’ or ‘Minimal Deal’ … from 1 January 2021, Great Britain will be completely outside the European Single Market, and the EU’s Construction Products Regulation Framework. The designation ‘Notified Body’ under that Framework will fall away from British Organizations. Construction Products/Systems manufactured in, or supplied from, Britain will then have to undergo an entirely new EU Testing and Approvals Programme in order to access the European Single Market. Fire Safety related Construction Products will have to be tested, and assessed or appraised, against all 7 Basic Requirements for Buildings together, during the same period of time (see Annex I, EU Regulation 305/2011) …
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
… a process which will be very interesting to observe, since the Fire Industry (particularly England’s Fire Establishment, AHJ’s, etc) dislikes, with intensity, the whole idea of ‘environmental impact’ … the concept of ‘sustainable development’ is hardly understood … and no consideration is given to the reasonable fire safety and accessibility needs of ‘vulnerable building users’ (including people with activity limitations, refugees, migrants, etc).
The tragic 2017 Grenfell Tower Fire, and its sad aftermath, have demonstrated how dysfunctional, and rotten to the core, is the whole national system of Building Fire Safety in England. More than 3 years later … on the evidence to date of an ongoing, incompetent Inquiry and a series of shoddy responses from Government … will survivors and the victims’ families ever receive Justice, and find Peace ? cf. The 1981 Stardust Discotheque Fire in Dublin. Survivors and victims’ families are still waiting for the truth to be revealed.
In parallel, mutual recognition of British Professional Building Designers, e.g. Architects, Structural Engineers, Fire Engineers, etc., within the European Union will cease.
In parallel, British Fire Research involvement in EU Research Networks will also cease … unless a heavy price is paid to be involved as a 3rd Country. British Institutions should forget any notions they might have about Network Leadership.
In parallel, Information and Data Flows between Britain and the EU will be disrupted or cease altogether … unless Britain complies fully with the requirements of EU General Data Protection Regulation (GDPR) 2016/679. As a vassal state of the USA, this compliance may prove difficult for Britain !
EU Fire Safety Related Product/System Manufacturers ~ A Word of Caution !
Many EU Construction Product/System Manufacturers continue to use the services provided by British Fire Test Laboratories and/or Fire Consultancy Organizations located in Great Britain … some of which have already established EU-based dummy companies and letterheads. These British organizations must be avoided altogether. For example, the practice of fire testing in England and later adding a title page of a Full Test Report with an EU location address is entirely unacceptable !
Essential Considerations for National Authorities Having Jurisdiction (AHJ’s):This Planet is Our Common Home – Be a Good Neighbour to Other Countries (Cuba is a Good Example, USA is a Bad Example) … Global Solidarity & Multilateral Collaboration in Co-Operation with the World Health Organization (WHO) … Act Fast … Perfection is the Enemy of the Good … The Precautionary Principle … Test-Test-Test … Return Test Results within 24 Hours … Trace Contacts within the Next 24 Hours … Collect, Collate and Openly Share Reliable Data & Statistics … Vulnerable People Require Equitable Safety Measures … Uphold and Protect Human & Social Rights.
[ Vulnerable People: Those people – in a community, society or culture – who are most at risk of being physically, psychologically or sociologically wounded, hurt, damaged, injured, or killed … and include, for example, People with Disabilities, Young Children, People with Health Conditions, Frail Older People, Women in Late Pregnancy, Refugees, Migrants, Prisoners, the Poor, and Homeless. ]
Essential Considerations for Each Person in a Community: Wash Hands Often and Properly (see Video below) … Wear a Mask in Outdoor and Indoor Public Spaces (see WHO Guidance below) … Social Separation / Physical Distancing … Be Careful, Always … Pay Attention to Your Mental Health (see UN Policy Brief below).
First Affiliated Hospital, Zhejiang University School of Medicine, China
The First Affiliated Hospital has treated 104 patients who tested positive for CoVID-19 in 50 days. It has achieved zero deaths in patients diagnosed, zero patients misdiagnosed, and zero infections in medical staff. Its experts documented real treatment experience when combating the virus, 24 hours a day, and quickly published this Handbook.
Public Health Emergencies often lead to Stigma, Discrimination and Abuse towards certain communities and social groups, or affected people. Within the context of CoVID-19, this has already happened … with the disease being recklessly and maliciously associated with a specific population or nationality.
Independent Oversight & Advisory Committee for the WHO Health Emergencies Programme
Established to facilitate on-line communication and collaboration internationally, as well as to provide Frontline Medical Teams around the world with the necessary communication channels to share practical experience about fighting, controlling and overcoming the pandemic.
The European Commission, together with several Partners, launched this Platform on 20 April 2020 … to enable the rapid collection and sharing of available Research Data. The Platform, part of the ERAvsCorona Action Plan (download PDF File, 153 Kb), is a significant effort to support Researchers in Europe and around the World in the fight against the CoronaVirus pandemic.
Vulnerable People, such as Those with Activity Limitations (#PwAL) or Disabilities (#PwD), are more impacted by #CoronaVirus/#CoVID19. These impacts can be mitigated if simple Self-Protection Measures are taken.
As Fire Departments and local Authorities Having Jurisdiction (AHJ’s) continue planning to respond to CoronaVirus/CoVID-19 occurrences in their communities, the IAFC Coronavirus Task Force has developed a guide to identify best practices … and key recommendations which are based largely on guidance from the U.S. Centers for Disease Control and Prevention (CDC – https://www.cdc.gov/) and the World Health Organization (WHO – https://www.who.int/emergencies/diseases/novel-coronavirus-2019). When planning for CoVID-19, Fire Chiefs must also be sure to collaborate with local Stakeholders, both individuals and organizations !
2020-03-23: The Grenfell Fire Inquiry’s Phase 1 Recommendations (Part V in Volume 4 of the Phase 1 Report), were published on 30 October 2019. The initial issues covered in those Recommendations are fragmentary, lack depth and coherence … and in the case of Fire Alarms, with just one indirect reference to them in Paragraph #33.22 … they are in serious error …
[ Paragraph #33.22 ] There were no plans in place for evacuating Grenfell Tower should the need arise. I therefore recommend:
d. that all high-rise residential buildings (both those already in existence and those built in the future) be equipped with facilities for use by the fire and rescue services enabling them to send an evacuation signal to the whole or a selected part of the building by means of sounders or similar devices ;
FUNDAMENTALS OF A SOLUTION
1. A Fire Alarm (more precisely from here on, a Fire Detection & Warning System) is a critical safety feature in all buildings … ALL BUILDINGS … from the smallest and most simple, to the biggest and most complex … no exceptions !!
In order to survive in a fire emergency, Vulnerable Building Users need more time to react, and evacuate, than other occupants/users. The valuable time provided by early, accurate and precise detection is the only way to effectively facilitate this. The ‘Required Time’ to prepare for evacuation depends on many factors, e.g. building complexity, familiarity of users with evacuation routes, range and severity of user activity limitations, etc.
It follows, therefore, that if building occupants/users have to wait 15, or 20, or 30 minutes before firefighters arrive at the fire scene (Full Response Time*) and ‘an evacuation signal to the whole or a selected part of the building’ is only then sent by those firefighters … all of that valuable evacuation time for vulnerable building users has been lost. This is ridiculous, and makes no sense whatsoever. This Recommendation must be rejected out of hand, and ignored !
[ *Full Response Time: The time interval from the receipt of an emergency communication at the primary public safety answering point (#PSAP) to when emergency response units are initiating action or intervening to control a fire incident. ]
Important Note: In Chapter #34: ‘Looking Ahead to Phase 2’ of Moore-Bick’s Phase 1 Report, Volume 4 … Paragraph #34.14 states …
A question was raised about the width of the stairs, given that they provided the sole means of access to the upper floors of the tower for firefighters as well as the sole means of escape for the occupants. However, the stairs appear to have complied with requirements of the legislation in force at the time of their construction and the expert evidence supports the conclusion that they had sufficient capacity to enable all the occupants of the building to escape within a reasonable time. This aspect of the building will not, therefore, be the subject of further investigation in Phase 2.’
Astounding ! Absurd !! FUBAR !!!
All Fire Emergency Warning Systems must be designed to accommodate People with Hearing Impairments. Audible and visual warning devices must be provided together, as a single combined unit. This is particularly important in noisy and isolated building spaces, e.g. bathrooms, small meeting rooms. Vibrating devices, such as pagers or mobile phones, can be integrated into a building’s fire emergency warning system in order to provide any individual with a tactile emergency alert.
Important Note: Audible sounders, on their own, are never a sufficient Fire Emergency Warning !
2. The Purpose of a Fire Emergency Warning System is to provoke calm, efficient and adaptable evacuation movement by ALL building users/occupants at the earliest possible stage in a fire incident, without causing user confusion, disorientation or panic. In all building types, therefore, a reliable, informative and accessible fire emergency warning system must be installed, and such a system must always have a fire protected electrical supply.
3. To provoke a Calm Response from Building Users … the output from Fire Emergency Warning Devices, e.g. light, sound and messages, must be adapted to the local context of people and building surroundings.
Fire Emergency Audible Warnings … A sufficient number of low-output audible sounders, i.e. between 60-80 dB, must be specified for effectiveness. Small numbers of sounders with high output (in order to reduce costs) should never be specified, as this can lead to confusion, disorientation and panic attacks among some building users/occupants. The output of sounders must be adapted to suit interior surroundings, e.g. in small spaces with hard surfaces a lower sound output will be adequate.
Important Note: When they are asleep, hearing-able children (around ten years of age and under) … and hearing-able older people (around 65 years of age and over) are more difficult to wake and rouse sufficiently for evacuation when alerted by an audible signal alone.
Fire Emergency Visual Warnings … Light strobes/beacons must be clearly visible. To reinforce #1 above … light strobes/beacons must be placed in wash rooms and in other locations within buildings where people may be alone ; they must also be placed in noisy environments.
A sufficient number of low-output strobes/beacons must be specified for effectiveness. Small numbers of strobes/beacons with high output (in order to reduce costs) should never be specified, as these produce a glare which may cause confusion, disorientation and panic attacks among some building users/occupants. The light output of strobes/beacons must be adapted to suit interior surroundings, e.g. in dark rooms.
For light strobes/beacons, a slow rate of flash is important, i.e. no faster than once every two or three seconds, in order to encourage a calm response from building users/occupants and to avoid photosensitivity seizures. Most importantly, the flash of one strobe/beacon must be synchronized with the flashes of all other light strobes/beacons in view.
Fire Emergency Voice Message Warnings … Are essential to improve Warning Credibility. In other words, building users are far less likely to sit around wondering, waiting to see whether this is a ‘real’ fire emergency, a false alarm, a practice evacuation, or an electrical error. Verbal or voice messages must be short and contain appropriate warning information which is easily assimilated. The speaker should be distinct and easy to understand. Live messaging during a fire emergency is preferred over pre-recorded, standard messages. In today’s multi-cultural social environment, messages must be transmitted in at least two to three different languages, as appropriate.
Fire Emergency Directional Warnings … Combination sounder, visible strobe/beacon, and voice messaging Fire Emergency Warning Devices are now a mainstream technology, are readily available, and are being specified in new and existing buildings.
Audible directional signalling must be installed when dealing with difficult building configurations, e.g. in large open office layouts/spaces with minimal signage … where building users/occupants are unfamiliar with their surroundings in modern shopping centres/malls and other complex building types … or visibility of high-level signage may be reduced because of smoke logging.
Directional sounders, which guide building users during a Fire Evacuation towards Exits, Areas of Rescue Assistance and Lift/Elevator Lobbies, must be positioned at carefully chosen, suitable locations. Once reached, a directional sounder must also have a voice messaging capability in order to inform people about the next phase of evacuation.
4. Fire Emergency Warning Systems must be Accessible (for People with Activity Limitations), i.e. capable of transmitting a warning in many formats in order to ensure that all users/occupants perceive and act upon the warning in a calm manner and, thereafter, that effective evacuation movement commences without delay. Warning Credibility improves in direct relation to the type and number of different warning formats.
As well as indirectly referring to Fire Detection and Warning Systems, Paragraph #33.22 in Moore-Bick’s Phase 1 Recommendations has some other things to say about Evacuation. So this is an opportune moment to discuss some practical and human issues concerning Fire Emergency Evacuation … and, straight away, to deal with an unexpected consequence arising from the current CoronaVirus/CoVID-19 Emergency …
CoronaVIRUS / CoVID-19 PANDEMIC
There have been widely reported instances, in many countries, of panic buying in shops because of the 2020 CoronaVirus/CoVID-19 Emergency … but the photograph below illustrates an example of a panic reaction by building management. This appears to be a crime scene … the yellow and black tape is so dramatic. In a real Fire Emergency, many building users/occupants will be reluctant to use this final fire exit ; they will not have the time to read the small print on a notice ; they will attempt to re-trace their path of evacuation and find another exit.
This panic reaction by building management IS a serious impediment to Fire Evacuation !
Whatever the Motives of Building Management …
in countries which have Fire Codes / Regulations, this action is illegal ; and
in these days, when a wide range of ‘smart’ technologies is readily available … this action is inexcusable.
SOME PRACTICAL FIRE EVACUATION ISSUES
A Skill is the ability of a person, resulting from competent training and regular practice, to carry out complex, well-organized patterns of behaviour efficiently and adaptively, in order to achieve some end or goal. All building occupants/users must be skilled for evacuation to an external ‘place of safety’, which is at a safe and remote distance from the fire building. Practice fire evacuations must be carried out sufficiently often to equip building users, particularly vulnerable users, with this skill, i.e. at least once every six months ; in complex building types, practices should be carried out more often. Prior notification to occupants/users, and regular scheduling of practice evacuations should be avoided.
Familiarity with Fire Evacuation Routes will be fostered and greatly improved by means of normal, everyday use by occupants/users. This is an important task for pro-active Building Management in existing buildings … and an important aspect of new building design for Architects and Fire Engineers.
While the transmission of fire emergency warnings in many formats will increase Warning Credibility, close observation of past tragic ‘real’ fire events, e.g. the WTC 9-11 Attacks in New York City, shows that initiation of evacuation and the actual process of evacuation itself can be problematic. An interesting, easily assimilated and user-targeted skills programme of training should incorporate practical solutions to deal with the following typical problems:
Fire Emergency Preparedness: Irregular attendance of building occupants/users at fire prevention and safety training sessions, and participation in practice fire evacuations. Users not being familiar with a building’s fire emergency management plan and not knowing who is in charge … not using a building’s fire evacuation route(s), particularly staircases, during practices … or having no information about where to assemble after evacuating … or, once at a place of safety, not having any head count or identification process ;
Delaying Activities Inside The Fire Building: Once building occupants/users decide to evacuate, but before moving to evacuate, they gather personal effects … seek out friends/co-workers … search for others … make phone calls/send tweets … finish tasks/turn off computers … wait around for instructions … change shoes … and try to obtain permission to leave ;
Delaying Activities Outside The Fire Building: Once outside the building’s final fire exit, but before moving directly to a place of safety, building occupants/users stop to see what is happening … look for friends/co-workers … look for a phone … do not know where to go … or, within the ‘danger zone’ of the fire building, stop to receive medical attention.
It may seem obvious that Fire Evacuation Routes must also be Accessible (for People with Activity Limitations), which also makes routes much safer for every other building user … and sufficiently wide to accommodate Contraflow (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) … a harsh lesson learned from the 2001 WTC 9-11 Attacks and the 2017 Grenfell Tower Fire. Since they are new, strange and unusual for many building designers, and most fire engineers … these aspects of building performance are overlooked in nearly every building.
Practice Evacuations should include exercise of the buddy system ; fire safety fittings, e.g. portable fire extinguishers ; and fire evacuation devices intended for use by people with activity limitations which will require more intensive training.
Important Note: During fire emergencies, People with Activity Limitations must be permitted to keep possession of their own personal Facilitation / Mobility Aids.
SOME HUMAN FIRE EVACUATION ISSUES
The actual people who use and occupy buildings are individuals. They are different from each other, and they each have a different range of abilities (in relation to self-protection, independent evacuation to an external place of safety remote from a fire building, and active participation in a building’s fire emergency management plan), behaviour and manner of perceiving their surroundings. Two apparently similar people will also show variations in how they react to and behave in any specific situation, particularly a fire emergency.
Ability / Disability is a Continuum – a gentle gradient on which every person functions and acts at different levels due to personal and environmental, i.e. external, factors.
In situations of severe stress, e.g. during a fire emergency in a building, where there is a lack of preparedness for such an event, a lack of familiarity with evacuation routes, lack of reliable evacuation information, lack of competent leadership and clear direction, and the presence of smoke, user/occupant confusion, disorientation and panic will occur. Standard evacuation movement times will also be non-existent. In addition, people with activity limitations must then deal with many physical barriers which routinely impede their evacuation from buildings, e.g. fire resisting doorsets which are difficult to open, steps along evacuation routes and at final fire exits.
In the case of people with a mental or cognitive impairment, there is a particular need to encourage, foster and regularly practice the adaptive thinking which will be necessary during evacuation a real fire incident.
People with respiratory health conditions will not be able to enter or pass through smoke. People with visual impairments will require continuous, linked tactile and/or voice information during the whole process of fire evacuation. People with psychological impairments, i.e. vertigo and agoraphobia, will be unable to use fire evacuation staircases with glass walls in high-rise buildings. Because of the stigma still associated with disability in many countries, some users/occupants who will need assistance during a fire emergency will be reluctant to self-identify beforehand. Other people may not even be able to recognize that they have an activity limitation or a health condition.
Meaningful Consultation with a person known to occupy or use a building, for the purposes of receiving his/her active co-operation and informed consent (involving a personal representative, if necessary), is an essential component of adequate pre-planning and preparation for a fire emergency.
Building Designers, Fire Engineers and Firefighters should be aware of the following human conditions:
Agoraphobia: A fear of open spaces.
Commentary: Agoraphobia is one of the most commonly cited phobic disorders of people seeking psychiatric or psychological treatment. It has a variety of manifestations, e.g. a deep fear of leaving a building, or of being caught alone in some public place. When placed in threatening situations, agoraphobics may experience a panic attack.
Anosognosia: A neurological disorder marked by the inability of a person to recognize that he/she has an activity limitation or a health condition.
Dementia: Any degenerative loss of intellectual capacity, to the extent that normal and occupational activities can no longer be carried out.
Panic: A sudden overwhelming feeling of anxiety, which may be of momentary or prolonged duration.
Panic Attack: A momentary period of intense fear or discomfort, accompanied by various symptoms which may include shortness of breath, dizziness, palpitations, trembling, sweating, nausea, and often a fear by a person that he/she is going mad.
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 …
… 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 …
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 ?????
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.
The Garden was officially opened in 1988.
Lasting Peace & Effective International Law are Essential Prerequisites for Sustainable Human & Social Development !
During the 12 Days of Christmas … Relax, Enjoy and Be Merry !!
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.
Office of California’s State Fire Marshal – November 2010
UL Report (2011): The Following Summarizes the Findings of This Fire Research Project:
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.
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.
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).
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.
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.
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.
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.
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.
Severing of conductors in both metal and plastic conduit results in electrical and fire hazards. Care must be exercised during ventilation and overhaul.
Responding personnel must stay away from the roofline in the event of modules or sections of an array sliding off the roof.
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.
As we drive harder and deeper (at least some of us anyway ?) towards a future of Sustainable Human & Social Development … or are forcefully driven by the anthropogenic (man-made) pressures of Resource Shortages (e.g. water – food – energy) and Climate Change, in the case of millions of people living in poverty throughout the world … or are dragged screaming, which I fear will have to be the solution with the privileged classes in every society who are addicted to lavish and wasteful lifestyles and who show absolutely no interest in either Climate Change or Resource Shortages until they rear up and bite them in the ass (!!) … there is a desperate need for a more complex and precise language of Sustainability, which will give shape to the innovative trans-sectoral concepts and trans-disciplinary policy and decision-making support tools required for Tangible/’Real’ Sustainability & Climate Resilience Implementation.
At the time of writing, the Principal Challenge before us is …
Transforming Social Organization … the Ultimate Goal being to arrive quickly at a dynamic and harmonious balance between a Sustainable Human Environment and a flourishing, not just a surviving, Natural Environment … with the Overall Aim of achieving Social Wellbeing for All.
Climate Change did not directly cause Hurricane Sandy, a severe weather event which hit the Caribbean and the East Coast of the USA during October 2012 … but it was a significant contributing factor. Scenes like those in the photograph below will be experienced far more frequently in the future.
This is not Manhattan, in New York City … so, is the development shown below to be removed altogether … or renewed with the necessary and very costly construction of a massive system of flood protection measures ? Not an easy choice. Which choice would be more sustainable ?
However … WHEN, not IF … Average Global Temperatures rise above 1.5 degrees Celsius, many Small Island Developing States (SIDS) will suffer a similar fate … permanently …
The Type of Lightweight Development in the foreground of the photograph below … damaged beyond repair or re-construction during Hurricane Sandy, is not Resilient … which is a different concept to Robust, or Robustness.
Notice the building in the background, on the left, which appears to have survived fully intact … why ??
In complete contrast … the Type of Development, below, is more Resilient. Furthermore, however, as a normal human reaction to decades of aggressive, but ultimately unsuccessful, political bullying and economic assault by the USA, the Social Fabric of Cuba is very strong … making this a Resilient Human Environment …
So … what is a Resilient Human Environment … particularly in the context of Sustainable Climate Change Adaptation ?
What do we mean by Transforming Social Organization ??
And … as we drive forward, harder and deeper … why is it critical that we practice a balanced, synchronous approach … across ALL Aspects of Sustainability … to Tangible Sustainability & Climate Resilience Implementation ???
Let us confront some more interesting new words and thought-provoking concepts …

Abridged Executive Summary
The term resilience originated in the 1970’s in the field of ecology from the research of C.S.Holling, who defined resilience as ‘a measure of the persistence of systems and of their ability to absorb change and disturbance and still maintain the same relationships between populations or state variables’. In short, resilience is defined as ‘the ability of a system to absorb disturbances and still retain its basic function and structure’, and as ‘the capacity to change in order to maintain the same identity’.
Resilience can best be described by three crucial characteristics: (1) the amount of disturbance a system can absorb and still remain within the same state or domain of attraction; (2) the degree to which the system is capable of self-organization; and (3) the ability to build and increase the capacity for learning and adaptation.
In the need for persistence, we can find a first connection with sustainable development. Sustainable development has the objective of creating and maintaining prosperous social, economic, and ecological systems. Humanity has a need for persistence. And since humanity depends on services of ecosystems for its wealth and security, humanity and ecosystems are deeply linked. As a result, humanity has the imperative of striving for resilientsocio-ecological systems in light of sustainable development.
Resilience thinking is inevitably systems thinking at least as much as sustainable development is. In fact, ‘when considering systems of humans and nature (socio-ecological systems) it is important to consider the system as a whole. The human domain and the biophysical domain are interdependent’. In this framework where resilience is aligned with systems thinking, three concepts are crucial to grasp: (1) humans live and operate in social systems that are inextricably linked with the ecological systems in which they are embedded; (2) socio-ecological systems are complex adaptive systems that do not change in a predictable, linear, incremental fashion; and (3) resilience thinking provides a framework for viewing a socio-ecological system as one system operating over many linked scales of time and space. Its focus is on how the system changes and copes with disturbance.
To fully understand resilience theory, the report focuses therefore on the explanation of a number of crucial concepts: thresholds, the adaptive cycle, panarchy, resilience, adaptability, and transformability.
As shown, humanity and ecosystems are deeply linked. This is also the fundamental reason why to adopt the resilience-thinking framework is a necessity for governance. The resilience perspective shifts policies from those that aspire to control change in systems assumed to be stable, to managing the capacity of socio–ecological systems to cope with, adapt to, and shape change. It is argued that managing for resilience enhances the likelihood of sustaining desirable pathways for development, particularly in changing environments where the future is unpredictable andsurprise is likely.
This exposes the strong need for Sustainable Development Governance to embrace resilience thinking. It is not only about being trans-disciplinary and avoiding partial and one-viewpoint solutions; what is needed to solve today’s problems – and especially those linked to sustainable development – is a new approach that considers humans as a part of Earth’s ecosystems, and one in which policies can more effectively cope with, adapt to, and shape change.
In this scenario, the concept and key characteristics of so-called adaptive governance seem to be a practical means for societies to deal with the complex issues that socio-ecological systems are confronted with. Therefore, adaptive governance is best understood as an approach that unites those environmental and natural resource management approaches that share some or all of the following principles: polycentric and multi-layered institutions, participation and collaboration, self-organization and networks, and learning and innovation. Additionally, four interactive crucial aspects for adaptive governance are suggested: (1) to build knowledge and understanding of resource and ecosystem dynamics; (2) to feed ecological knowledge into adaptive management practices; (3) to support flexible institutions and multilevel governance systems; and,(4) to deal with external disturbances, uncertainty, and surprise. Therefore, nine values toward a resilient world are also suggested: diversity, ecological variability, modularity, acknowledging slow variables, tight feedbacks, social capital, innovation, overlap in governance, and ecosystem services.
Finally, three examples analyse practical instances in terms of resilience: (1) the approach taken by the so-called climate change adaptation discourse; (2) the Kristianstad Water Vattenrike, a wetland in southern Sweden that showed problems with loss of wet meadows, decline of water quality, and a disappearing wildlife habitat; and 3) the Goulburn-Broken Catchment from the State of Victoria (Australia). Some lessons can be drawn from these three cases. From the first case, governance structures have direct implications for the level of flexibility in responding to future change as well as variation in local contexts. Sensitivity to feedbacks relates both to the timing as well as where these feedbacks occur. Therefore, learning is more likely if feedbacks occur soon relative to action, and if those most affected by feedbacks are those responsible for the action. Additionally, the way in which a problem is conceptually framed determines the way in which responses are identified and evaluated and therefore influences the range of response characteristics. Second, the example from Sweden revealed that (a) the imposition of a set of rules to protect an ecosystem from the outside will not ensure the natural qualities of a region will be preserved over time. One size never fits all, and an understanding of local history and culture needs to be integrated into the management if local values are to be looked after; (b) for an organization to meaningfully deal with complexity at many scales, it needs to include representatives from each of these levels in the social network; (c) several organizations need to be prepared to contribute to a shared vision and build consensus and leadership – crucial components in adaptability and transformability. Third, the Goulburn-Broken story demonstrates the critical importance of understanding the underlying variables that drive a socio-ecological system, knowing where thresholds lie along these variables, and knowing how much disturbance it will take to push the system across these thresholds.

– FireOx International is the Fire Engineering Division of Sustainable Design International Ltd. (SDI) –
Fundamentally, the 9-11 World Trade Center Incident in New York (2001) was an Extreme ‘Real’ Fire Event. It presented the International Fire Engineering Community with a catastrophic failure in conventional practices and procedures related to:
Fire Engineering, Structural Engineering, and Architectural Design ;
Human Building Management Systems ;
Emergency Response by Firefighters, Rescue Teams, and Medical Personnel ;
National and Local Organizations Having Authority or Jurisdiction (AHJ’s) ;
… and with the serious problem of entirely inadequate Fire Safety Objectives in the building legislation, model codes and design standards of the most economically advanced countries in the world.
Those people who understand the building design process, and have experience as construction practitioners, have long realised that the lessons from 9-11 must be applied across the full spectrum of building types … not just to tall buildings. Right up to the present day, unfortunately, many people in the International Fire Engineering Community are either unwilling, or unable, to do this.
Furthermore … Fire Engineering, Architectural Design and Structural Engineering must, of urgent necessity, be seamlessly conjoined … with the aim of removing misunderstandings and the wide gaps in client service delivery between the different disciplines.
In 2002, a series of Long-Term 9-11 Survivor Health Studies commenced in the USA … and in 2005 and 2008, the U.S. National Institute of Standards and Technology (NIST) issued a series of Post 9-11 Critical Recommendations concerning the design, construction, management and operation of buildings.
At FireOx International … we have fully integrated this essential design guidance into our frontline fire engineering and architectural practice … we have developed unique and practical solutions for worldwide application, some of which appear in International Standard ISO 21542: ‘Building Construction – Accessibility & Usability of the Built Environment’, published in December 2011.
FireOx International’s Commitment to You
As a necessary response to the New 21st Century Paradigm of Real Extreme Event in a Built Environment which is becoming more and more complex … is subject to climate change and severe weather events … and is vulnerable to malign and malevolent disruption –
WE are committed to … the implementation of a Sustainable Human Environment which is Fire Safe and Secure for All, meaning that an ‘appropriate project-specific fire safety level’ is our fire engineering objective, with ‘human health protection’ targeted as a priority … through the use of innovative, reliability-based and person-centred sustainable design practices and procedures.
What is an ‘Appropriate Fire Safety Level’ in Your Building or Facility ?
It is rarely, if ever, explained to clients/client organizations that the Minimal Fire Safety Objectives in building legislation are focused solely on protecting the ‘interests’ of society, not those of the individual … are, quite often, inadequate and/or flawed … and are, always, revised only after the latest tragedy !
To properly protect Your Interests as a client/client organization … we strongly advise that the Appropriate Level of Fire Safety in Your Building or Facility should exceed the minimal level of safety required by building legislation. We would also caution that, in many jurisdictions (e.g. India), compliance with national building legislation is voluntary.
Which raises the issues of whether or not you will actually get what you pay for, and whether or not the Fire Protection Measures in Your Building or Facility are reliable (in other words, will they perform as intended at the time of a ‘real’ fire, which may occur at any time in a building’s long life cycle) !?! Competent Technical Control of Design and Construction, independent of the design and construction organization(s), is essential.
You should carefully consider the following spectrum of issues which may be directly relevant to Your Project. Following a process of consultation with you, we then develop Project-Specific Fire Engineering Design Objectives … bearing in mind that you must also comply with safety at work, anti-discrimination, and environmental legislation, etc … maintain business continuity, etc … be energy efficient, etc … and be socially responsible, etc …
– Protection of the Health of All Building Users … including People with Activity Limitations (2001 WHO ICF), Visitors to the building or facility who may be unfamiliar with its layout, and Contractors or Product/Service Suppliers temporarily engaged in work or business transactions on site ;
– Protection of Property from Loss or Damage … including the Building or Facility, its Contents, and Adjoining or Adjacent Properties ;
– Safety of Firefighters, Rescue Teams and Other Emergency Response Personnel ;
– Ease and Reasonable Cost of ‘Effective’ Reconstruction, Refurbishment or Repair Works after a Fire ;
– Sustainability of the Human Environment (social – built – virtual – economic) … including Fitness for Intended Use and Life Cycle Costing of fire engineering related products and systems, etc … fixed, installed or otherwise incorporated in the building or facility ;
– Protection of the Natural Environment from Harm, i.e. Adverse or Damaging Impacts.
