This WebPage began life as an Appendix to a 1999 International Paper presented in Belgium by
C.J. Walsh - Chief Technical Officer, FireOx International.

Original Figures, Drawings and Graphics are now being updated to show current state-of-the-art,
and integration into 'mainstream' fire engineering of adequate fire protection for people with activity limitations.
Our future work will look more closely at adequate safety for firefighters/rescue teams.


Update of WebPage in Progress:
March 2010

 

Far too many people in decision-making roles and/or positions of authority
believe that, no matter what the type of building,
Management Procedures, alone, will be sufficient to deal adequately with the
Fire Evacuation of People with Disabilities / Disabled People.
This is unrealistic .... and entirely untrue !

Some people even believe that this issue may be dealt with as an
Appendix to the Main Body of an Accessibility-Related Standard or Design Manual.
This is a fairytale for children !

To be Cost-Effective in New Buildings .... Fire Evacuation-for-All
must be considered at the beginning of the Design Process.

Before implementing any of the Fire Engineering Principles illustrated below,
it is very important that you seek the advice of
a 'competent person', i.e. an experienced Fire Engineer
.

Fire Evacuation-for-All !

We expect buildings to be designed for access, with beautiful entrance lobbies and immediately
obvious elevators / lifts.  But are buildings ever designed for fire evacuation, or is it usually
necessary to have a magnetic compass, a map and a magnifying glass to find the nearest
fire evacuation route ?

Building Designers must begin to understand 'design for evacuation' !



A New European Context for Accessibility

Protection from Fire in Buildings is now robustly embedded in the definition
and implementation of Accessibility-for-All.

The Legal Environments at European Level and in the EU Member States
clearly mandate that the broad range of users and visitors to buildings
be properly considered in the work of Fire Engineers.

 

Furthermore .... Article 11: 'Situations of Risk & Humanitarian Emergencies'
in the recently adopted (December 2006) United Nations Convention on the Rights of Persons with Disabilities ....

' States Parties shall take, in accordance with their obligations under
international law, including international humanitarian law and
international human rights law, all necessary measures to ensure the
protection and safety of persons with disabilities in situations of risk,
including situations of armed conflict, humanitarian emergencies and the
occurrence of natural disasters.'

For clarity and ease of translation into the different European languages, the term 'Refuge'
should be replaced with Area of Rescue Assistance.

To define Place of Safety, see this 2002 Paper presented in Sweden by C.J. Walsh.

Fire Evacuation Routes must also be accessible !

Compare this Figure carefully with Figure 1 in British Standard BS 5588:Part 8:1999.
Try to identify the errors in BS 5588:Part 8.


With regard to this British Standard - see our
Submission #1 to the Department of the Environment in Ireland

We stated in this Submission, dated 1999-10-27, to Minister Noel Dempsey T.D., Minister for the Environment ....
" Regrettably, it must now be finally and clearly stated, for public record, that the guidance
offered in Technical Guidance Document B, concerning the protection of disabled people from
fire in buildings, is entirely inadequate. Use of the British Standard which is referenced in
TGD B (BS 5588 : Part 8), while it introduced some innovative and badly needed fire
engineering concepts at the time of its publication, must now also be thoroughly reviewed in
Ireland. The Standard's drawings, for example, are dangerous and inept. Furthermore, some
of the contents of the Technical Guidance Document and the British Standard actually conflict
with other provisions of the Irish Building Regulations."

No Proper Response Has Ever Been Received From The Minister or The Department.

 

On 29th November 2006, similar comments were sent directly to the British Standards Institute (BSI) by e-mail.

No Response Has Ever Been Received From BSI.

On 31st October 2008, BSI published BS 9999 - 'Code of Practice
for Fire Safety in the Design, Management and Use of Buildings'.

This Standard has replaced British Standard 5588 : Part 8.

Extracts from 'Conclusions' ...

There are many gaps and conflicts between these two British Standards, principally
because ... they are two separate standards ... drafted by two different Technical
Committees within the British Standards Institution.

Input from the Disability Sector during the drafting of BS 9999:2008 was not at all
sufficient to ensure that there was a meaningful consideration of the problems
encountered by people with activity limitations during a 'real' building fire incident. The
necessary range of available and effective fire engineering solutions has not, therefore,
been presented in the standard.

In addition, the complete and abject failure to consider the important Recommendations
contained in the 2005 & 2008 National Institute of Standards & Technology (USA)
Reports on the WTC 9-11 Incident in New York was an inexcusable and unforgivable
technical oversight.

The result is a crassly inadequate, discriminatory and deeply flawed national fire safety
standard in Great Britain & Northern Ireland. BS 9999:2008 became obsolete on the
very day of its publication !

Figure 3.






Manual Handling of an Occupied Wheelchair on an Evacuation Staircase is not consistent
with the requirements of European Union Safety at Work Legislation.
Even with adequate training, it is hazardous for the person in the wheelchair and those people - minimum three - giving assistance.

Lifts/Elevators in New Buildings must be capable of being used for evacuation in a fire situation.

Lifts/Elevators in Existing Buildings - At the latest when being replaced or undergoing a major overhaul,
they must then be made capable of being used for evacuation.

For more information about Assisted Evacuation, see this 2002 Paper presented in Sweden by C.J. Walsh.

Figure 4.




Fig.4  Minimum Staircase Width for Fire Evacuation



When in an open or partially-open position, a door leaf should not encroach on any
Staircase Evacuation Travel Space. People moving to 'areas of rescue assistance',
with/without wheelchairs or other facilitation aids, should also not encroach on evacuation travel space.

Handrails should be continuous throughout. See Figure 5b.


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

This is now the preferred term, rather than 'Refuge'; it explains, clearly and directly, what
the function of this space is ... in language which can be easily translated into French, Spanish, Italian and German, etc.


The Clear Staircase Width shown above (approximately 1.5 m. between handrails) permits assisted evacuation
of 'people with activity limitations' (2001 WHO ICF).  See Figure 3.

This width also permits Contraflow Movement ... the simultaneous and unobstructed
access by heavily equipped firefighters, while building user evacuation is in progress.

 


A Fire Evacuation Supply Kit should be available in each Area of Rescue Assistance.
Also included should be suitable gloves (which are used to protect a person's hands from debris
when pushing his/her manual wheelchair), patch kits to repair flat tyres, and extra batteries for
those who use motorized wheelchairs or scooters.

Fire Officers and Evacuation Assistants should receive Proper Training from Competent Persons.
Training should include: a range of evacuation assistance techniques to use in different situations, particularly how to carry people,
with/without their Facilitation Aids; the use of any special evacuation assistance equipment, e.g. Evacuation Chairs;
and training in basic sign language to communicate effectively with people who have a hearing impairment,
with additional instructions for those who use Evacuation Assistance Animals.

A Reliable & Effective Fire Warning System Is Always Essential !

On Projects of Every Size .... At a Minimum, warning information must always be communicated by Sounder & Strobe.
Available technologies now readily facilitate that warning information can be simultaneously communicated
by sounder, light strobe/beacon, voice message and individual tactile sensation by vibration.

Always specify a Large Number of Sounder/Strobe Units with Low Output - never a small
number of sounder/strobe units with high output.

Sounder - between 85-95dB (adapt output to suit surroundings - min 15dB above max ambient
sound in small spaces). People must also be able to give or understand verbal instructions in the
vicinity of a sounder.

Strobe - always ensure a slow rate of flash (e.g. once every 2 seconds). Flash must be
synchronized with other strobes in view (adapt output to suit surroundings). Strobe must be
noticed, but not be so bright that extreme glare and/or disorientation results.

Voice - a short message should contain appropriate warning information which is easily
assimilated. Speaker must be distinct and easy to understand.
Remember that in today's multi-cultural Europe ... not everybody understands English !

N.B. Children under ten years of age, who are asleep, are more difficult to wake than adults.

Figure 6.






Fire Resisting Doorset / Shutter Assembly
A doorset / shutter assembly, suitably installed or mounted on site, the function of which
is to resist the passage of heat, smoke and flame for a specified time during a fire.

The term 'fire door' has no meaning, and should not be used - Not Ever - Never !


Resistance to Opening of Fire Resisting Doorsets
The resistance to opening of internal fire resisting doorsets should not exceed 8 Nm.



Element of Construction
(ISO 1791)
A functional part of a building, constructed from building materials and/or building components.

Examples are foundation, floor, roof, wall, etc.

Fig.6a  'Reliability' ... of Fire Test Results?


Because of widespread differences in fire test furnace construction throughout
the European Union - which lead to difficulties with test repeatability and reproducibility
(see ISO 5725 : Precision of Test Methods) - a period of fire performance may only be validly
claimed if 'actual performance' exceeds 'claimed performance'
by 10%, or a minimum of 10 minutes, whichever is the greater
.

Figure 7.



 

Buildings must be designed for Multi-Stage Fire Evacuation.


Place of Relative Safety
Any location beyond the Buffer Zone surrounding a Fire in a building.


For Reliability, a single Fire Resisting Element of Construction is not sufficient for Separation.

A Buffer Zone is four-dimensional - it completely surrounds the Fire Compartment - to the sides,
and above and below on different floors.
And as the Fire spreads in time, so the Buffer Zone expands with it.


Example Above in Fig. 7

If a Fire starts in Zone A - everyone is immediately evacuated from Zone A and the Buffer Zone surrounding Zone A (shaded black).

Zone B would be a Place of Relative Safety.

People in a Place of Relative Safety should always be fully informed, and be ready to evacuate
at a moment's notice.
People in Zone C should continue with their activities, as normal. This is especially useful,
for example, in the case of hotels at night.

Once the Fire (heat, smoke or flame) spreads to any part of the Buffer Zone between Zone A and Zone B - Zone B is no longer a Place of Relative Safety.

Zone B should be evacuated immediately.

Zone C then becomes a Place of Relative Safety.


Evacuate a Fire Building
To withdraw, or cause to withdraw, all users from a fire building, in planned and orderly phased
movements, to a Place of Safety.

To define Place of Safety, see this 2002 Paper presented in Sweden by C.J. Walsh.

Safe Evacuation for All
In Cultural Buildings



Elena Siré, Architect

Staffan Bengtson, Fire Consultant
& Lena Kecklund, Psychologist

Click Here to Contact Main Author


Improving evacuation safety for people with activity limitations is not an insurmountable problem - not even when converting buildings of great cultural value.

Safe Evacuation for All deals with such important concepts as accessibility and personal safety. In the preservation of architecturally valuable buildings, attention also has to be paid to cultural values and architectural considerations. Different people have differing opinions about the nature of risk. This book contains a presentation of how people behave in the event of fire and other hazardous situations. Evacuation drills indicate which requirements must be met if people with activity limitations are to be able to evacuate.

This book also contains case studies which will serve as a source of inspiration as well as providing a knowledge base. There is also a section on technical advice and instructions.
