Question 1

What is the PASS technique for using a fire extinguisher?

Accepted Answer

Pull the pin, Aim at the base, Squeeze the handle, Sweep side to side

Answer

PASS stands for: Pull the pin, Aim the nozzle at the base of the fire (not the flames), Squeeze the handle to release the agent, and Sweep the nozzle from side to side across the base of the fire.

Question 2

What is a Class F fire?

Accepted Answer

A fire involving cooking oils and fats

Answer

Class F fires involve cooking oils and fats at high temperatures. They require special wet chemical extinguishers. Never use water on a Class F fire as it can cause a violent fireball (boilover). These are relevant to site canteens.

Question 3

What should you do if you discover a fire on a construction site?

Accepted Answer

Raise the alarm, call the fire brigade (999), evacuate to the assembly point, and only fight the fire if trained and it is safe to do so

Answer

The priority sequence is: raise the alarm (activate the nearest break glass point), call 999, evacuate via the nearest safe route to the assembly point. Only attempt to fight a small fire if you are trained and it is safe to do so.

Question 4

What is the purpose of fire compartmentation in a building under construction?

Accepted Answer

To contain fire and smoke within a defined area, limiting spread and protecting escape routes

Answer

Fire compartmentation uses fire-resistant walls, floors, doors, and fire stopping to contain fire and smoke within a defined area. This limits fire spread, protects escape routes, and gives occupants time to evacuate safely.

Question 5

What is the role of a fire marshal on a construction site?

Accepted Answer

To assist with evacuation, check that all persons have left their area, and liaise with the fire brigade on arrival

Answer

Fire marshals assist with orderly evacuation, sweep their designated area to ensure everyone has left, report to the chief fire marshal at the assembly point, and liaise with the fire brigade, providing information about the fire location and any persons unaccounted for.
