Fire Safety Management Flashcards

What is the difference between an L1, L2, and L3 fire detection system category under BS 5839?

Answer: L1 protects the whole building, L2 protects defined areas including escape routes, and L3 protects escape routes only

BS 5839-1 categorises automatic fire detection systems: L1 provides detection throughout all areas of the building for maximum life safety. L2 provides detection in specified areas (high-risk rooms plus escape routes). L3 provides detection in escape routes only (corridors, stairways, landings) to give early warning for safe evacuation.

A dry powder extinguisher is identified by which colour band?

Answer: Blue

A dry powder extinguisher has a blue colour band on a red body. It is versatile and can be used on Class A, B, and C fires, plus electrical fires. The powder works by chemical inhibition of the chain reaction. However, it provides no cooling effect, so re-ignition is possible, and it should not be used in enclosed spaces.

What is the 'stay put' evacuation strategy and where is it typically applied?

Answer: Occupants in the fire-affected flat evacuate while others remain safely in their own compartments unless directly threatened — used in purpose-built blocks of flats with adequate compartmentation

The 'stay put' strategy is used in purpose-built blocks of flats where each flat is a separate fire compartment with fire-resisting construction. Occupants of the affected flat evacuate immediately, while other residents stay safely in their own flats unless threatened by smoke or fire. This depends on adequate compartmentation and fire-resisting doors being maintained.

What are the main causes of fire in the workplace according to UK fire statistics?

Answer: Deliberate ignition (arson), electrical faults, smoking materials, heating equipment, and cooking appliances

UK fire statistics consistently show the main causes as: deliberate ignition (arson) which is the leading cause in non-domestic premises, faulty electrics (overloaded sockets, damaged cables, poor maintenance), smoking materials, misuse of heating equipment, cooking accidents, and hot work activities such as welding and cutting.

What fire safety training must be provided to employees under UK fire safety legislation?

Answer: Fire risks in the workplace, actions on discovering a fire, how to raise the alarm, evacuation procedures, assembly point locations, and use of firefighting equipment where appropriate

The RR(FS)O 2005 requires the responsible person to provide employees with comprehensible and relevant fire safety information and training. This must cover fire hazards and risks, preventive measures, emergency procedures, alarm systems, escape routes, fire warden duties, and use of firefighting equipment. Training must be given on induction, periodically repeated, and updated when risks change.

What is the purpose of fire safety signage complying with the Health and Safety (Safety Signs and Signals) Regulations 1996?

Answer: To provide clear visual information about escape routes, fire exits, firefighting equipment locations, fire action notices, and prohibited actions

Fire safety signage provides essential visual communication including: green signs for escape routes and exits, red signs for firefighting equipment locations, fire action notices at call points, prohibition signs (no smoking), and directional arrows. Signs must be photoluminescent or illuminated to remain visible during power failure and comply with BS 5499 and ISO 7010.
