Fires in schools are common – there are around 20 fires a week reported, of which one third are in school hours. Fortunately there haven’t been any recent fatalities but 85% of the property losses in schools are due to the effects of fire.
However a fire risk assessment is a different matter – although school administrators and teachers are used to identifying risks and applying common sense to reduce them, producing a fire risk assessment for such a complex environment needs more specialised knowledge. Downloaded forms are unlikely to be adequate for the job.
Compartmentation is the key
It’s tempting to look at fire precautions in schools – the sprinklers where fitted, the alarms, the fire exits and signs, the extinguishers, and think “that’s it, we’re covered”. But although all those things are important, if the fabric of the building isn’t fire-safe there might not be the opportunity to use them. Built-in fire protection forms the basis of fire safety; if it is in place then active measures have time and opportunity to work.
Compartmentation is the key. Using fire separating elements such as fire doors, seals, fireresistant glass, partitions and ducting inhibits the spread of fire, confining damage to as small an area as possible, while preserving exit routes and allowing safe access for firefighters. But it is not realistic to expect school staff to be aware of compartmentation and all the factors involved in preserving it – outside the fire safety industry the concept is almost unknown.
Even if the responsible person is aware of built-in fire protection the temptation is to think of it as unchanging but school buildings are often changed, added to, re-configured. Every time there is an alteration or addition which changes or penetrates a fire-safe compartment element that element may be compromised. All new pipes, wires, ducts, doors and light fittings can provide a way for smoke, heat and flames to spread through a school, to break out in seemingly unrelated areas.
Unfortunately the construction of many schools between the 1950s and the 1980s, using the Consortium of Local Authorities Special Programme (CLASP) didn’t help – the buildings were mostly steel framed to allow easy re-configuration (except where they contain asbestos, but that’s a different can of worms). This ease of alteration means the original compartmentation may be lost. The quality wasn’t brilliant in the first place and by the time these buildings have decayed and been patched up the built-in fire protection is seriously compromised. Re-fitting computer rooms, updating the heating, changing the lights; they all provide opportunities to penetrate the fire safety element.
Risk assessments must be completed by a qualified professional
A ‘suitable and sufficient’ risk assessment for fire safety must be conducted by a competent person, which in the case of a school is unlikely to be a member of staff. It should be done by someone who can assess the passive protection as well as the active measures. But even if the school employs a professional risk assessor it is essential to check their credentials.
Assessor is the space above a suspended ceiling. If fire penetrates this area it can spread unchecked, unless fire barriers have been erected to coincide with the fire separating elements on the operational floors. It isn’t an obvious hazard but a certified Risk Assessor will know to check it.
More than just box ticking
Although the first aim of any fire protection is to preserve lives it is also important to protect property. Unfortunately arson is a major cause of school fires, usually happening when the buildings are empty. Basic good housekeeping can help minimise the risk – not having combustible materials within easy reach outside – but a determined arsonist will find a way. Good compartmentation will help restrict damage to the immediate area and prevent the spread of smoke and flames. Schools with sound built-in fire protection are more likely to re-open quickly after a fire, with less disruption as there will be unaffected areas. But recognising built-in fire protection requires more awareness than can be gained from filling in a simple form and ticking a few boxes. Common sense is a valuable commodity but it isn’t enough for a fire risk assessment. Schools and their occupants are too vulnerable and valuable to trust to anything other than the best available protection. A good, up-to-date and thorough risk assessment plays a major part in ensuring it.
