CITB Fire Safety 3

Question 1

What is a fire assembly point and why is it important?

Accepted Answer

A designated safe location outside the building where all persons muster after evacuation to be accounted for

Answer

The assembly point is the pre-designated safe gathering place; mustering there allows a roll call to confirm everyone has evacuated and identifies anyone who may still be in the building.

Question 2

Which gas poses a serious fire and explosion risk in construction excavation and confined space work?

Accepted Answer

Methane (natural gas)

Answer

Methane is flammable across a range of 5–15% in air and can accumulate in excavations and confined spaces from disturbed ground, sewers, or landfill gas — a single spark can cause an explosion.

Question 3

When selecting a location to store flammable liquids on a construction site, which factor is most important?

Accepted Answer

A well-ventilated, secure area away from ignition sources, other flammable materials, and escape routes

Answer

Flammable liquid storage must be ventilated to prevent vapour build-up, secure to prevent tampering, and separated from ignition sources with safe access and egress routes unaffected.

Question 4

What is the difference between a fire precaution and a fire prevention measure?

Accepted Answer

Prevention measures reduce the likelihood of fire starting; precautions protect people and property after a fire starts

Answer

Prevention measures reduce ignition risk; precautions protect people once a fire has started — alarms, extinguishers, escape routes, and assembly points are all fire precautions.

Question 5

Which construction scenario poses the highest fire risk from arson?

Accepted Answer

Unoccupied sites with poor perimeter security and accumulated combustible waste

Answer

Unoccupied sites with accumulated waste and inadequate security attract arsonists — good housekeeping, waste removal, and perimeter security are key preventive measures.
