Fire Protection Systems and Fire Safety
This section covers Fire Protection Systems and Fire Safety: detection, suppression, means of escape and the legal duties on premises. The exam tests alarm categories, sprinklers, risers, smoke control and the Regulatory Reform (Fire Safety) Order 2005 in England and Wales.
Systems
- Fire alarm categories: L for life protection (L1 highest, L5 lowest), P for property protection, M for manual.
- Sprinklers: wet, dry, pre-action and deluge; they control or suppress but do not replace evacuation.
- Dry risers serve upper floors and are charged by the fire service; wet risers are permanently charged.
- Smoke control uses natural or mechanical ventilation to keep escape routes tenable.
Fire safety duties
- The Fire Safety Order applies to non-domestic premises and common parts; the responsible person must assess risk and maintain precautions.
- Means of escape, signs, emergency lighting, fire doors and records must be maintained.
- Domestic premises are generally outside the Order; home safety visits are a separate prevention activity.
Worked example
A mixed-use building has shops below flats. The common stair is a relevant area under the Order; the responsible person must keep fire doors self-closing, maintain the alarm and emergency lighting and record checks. A shop's stock blocking the stair is a serious breach because it compromises the escape route for residents.
Traps
Confusing L and P categories; assuming sprinklers mean no evacuation; treating a dry riser as charged; applying the Order to a private flat.
