Fire Safety Flashcards
What are some different types of passive fire protection?
Containing fire. Fire stopping, fire collars, fire doors, cavity barriers, non combustible external wall.
What are some different types of active fire protection?
Detecting, stopping and escaping fire. Sprinklers, fire detectors, AOV, fire exit signage, firefighter lift.
What is the biggest difference between passive and active fire protection?
Passive contains and active detects, stops and allows escape of fire.
Name the different types of fire detection?
- Smoke detectors
- Heat detectors
- Flame detectors
- Carbon monoxide detectors
Different Categories:
- Cat M manual
- Cat P property
- Cat L life
- Cat LD life domestic
Explain the different types of riser? At what heights are they required?
Risers are a system of pipes enabling water to a building. Dry riser 11m+ dry valves and pipework enabling fire service to pump water. Wet riser 50m+ wet valves and pipework permanently charged with water generally utilising pumps and tanks.
Explain the different types of smoke extraction?
Natural works without additional ventilation drivers such as windows, skylights, AOVs, they automatically open and help remove smoke.
Mechanical includes powered fans which extract smoke and can have a smaller shaft.
Smoke reservoirs include areas which aim to contain smoke by utilising automatic drop smoke barriers.
What is the purpose of a fire strategy? What is included and which person is responsible for?
Means of warning, means of escape, passive fire protection, protection against external fire spread, fire service access and facilities, fire safety management measures.
Responsible person who is owner or manages the building should review fire strategy yearly or if the building changes.
A fire strategy plan defines the fire safety objectives and performance requirements for a building and the methods by which these will be achieved.
Who is the responsible person and what is their role?
The client or the person who is responsible for managing the property.
Responsible for ensuring the fire strategy is up to date and it is implemented accordingly. Ensures the safety of the building in terms of fire.
What are the categories included in Approved Doc B?
Part B contains guidance on fire safety, including means of escape, fire spread, structural fire protection and fire service access.

What are the most recent changes to Approved Document B?
- The ban on combustible materials in and on the external walls of buildings, introduced in 2018, will now apply to hotels, hostels and boarding houses
- Restricting the use of ACM cladding.
- Recommendation for buildings over 18m to have an evacuation alert system
- Restrictions in use of combustible materials in buildings over 11m
- Sprinklers in all new blocks of flats over 11m
Who is defined as the responsible person?
The Fire Safety Order defines the Responsible Person as anyone who has control or anyone who has a degree of control over certain areas within the premises. This could be the owner, employer or occupier.
When should a wet riser be implemented and when should a dry riser be implemented?
Dry riser is 11m+
Wet riser is 50m+
What are key differences between the main two types of smoke extraction?
Natural incorporates smoke naturally rising whereas mechanical uses powered fans.
Mechanical can usually have a narrower smoke shaft.
Mechanical can draw out smoke quicker.
Natural is normally more cost effective but it depends on the building.
What materials are used for fire stopping?
- Ablative batts
- Graphite fire stopping
- Acrylic fire stopping
- Fire collars
- Fire rated plasterboard
- Fire wraps
- Fire doors
