NEBOSH CC Fire Prevention in Construction 4

Question 1

What is the primary purpose of a fire door on a construction site or building?

Accepted Answer

To resist the passage of fire and smoke between compartments, maintaining means of escape

Answer

Fire doors are specifically designed to resist the passage of fire and smoke between fire compartments for a specified period (e.g., FD30 for 30 minutes, FD60 for 60 minutes). They maintain the integrity of escape routes and limit fire spread.

Question 2

What fire-fighting action should a worker take when discovering a small fire on a construction site?

Accepted Answer

Raise the alarm first, then attempt to tackle the fire with an extinguisher only if safe to do so and the fire is small

Answer

The priority is always to raise the alarm to warn others. Only then should a worker attempt to fight the fire if it is small (not bigger than a wastepaper basket), they are trained to use an extinguisher, there is an escape route behind them, and they are not at risk.

Question 3

What does the acronym PASS stand for in the context of using a fire extinguisher?

Accepted Answer

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

Answer

PASS is the standard technique for using a fire extinguisher: Pull the safety pin, Aim the nozzle at the base of the fire, Squeeze the trigger handle to release the extinguishing agent, and Sweep from side to side at the base of the flames.

Question 4

What is fire compartmentation and why is it important in construction?

Accepted Answer

Dividing a building into fire-resistant sections to limit fire spread and protect escape routes

Answer

Fire compartmentation uses fire-resisting walls, floors and doors to divide a building into sections. If a fire starts in one compartment, it is contained for a defined period, allowing evacuation and limiting damage. It is fundamental to building fire safety.

Question 5

Which class of fire involves cooking oils and fats?

Accepted Answer

Class F

Answer

Class F fires involve cooking oils and fats, typically in kitchen environments. These fires cannot be extinguished with water (which causes a violent steam explosion) and require a wet chemical extinguisher specifically designed for this type of fire.
