CITB Fire Safety

Question 1

What are the three elements of the fire triangle required to sustain a fire?

Accepted Answer

Fuel, oxygen, and heat (ignition)

Answer

Fire requires all three elements: fuel, oxygen, and heat — remove any one and the fire goes out, which is the basis of all fire prevention and fighting strategies.

Question 2

Which extinguisher type is safe to use on electrical fires?

Accepted Answer

CO2 (carbon dioxide)

Answer

CO2 extinguishers are non-conductive and leave no residue, making them the correct choice for live electrical equipment fires; water and foam conduct electricity.

Question 3

Under the Regulatory Reform (Fire Safety) Order 2005, who is responsible for fire safety in a workplace?

Accepted Answer

The 'responsible person' — typically the employer, owner, or person in control of the premises

Answer

The RRO 2005 places the duty on the 'responsible person' to conduct fire risk assessments, implement preventive measures, train staff, and maintain fire precautions.

Question 4

What is the purpose of a fire risk assessment on a construction site?

Accepted Answer

To identify fire hazards, people at risk, and measures needed to eliminate or reduce those risks

Answer

A fire risk assessment systematically examines the site to find sources of ignition, fuel, and oxygen; identifies who may be harmed; and determines what control measures are needed.

Question 5

What does a green fire safety sign indicate on a construction site?

Accepted Answer

An emergency escape route, exit, or assembly point

Answer

Green signs indicate safe conditions — in fire safety they identify escape routes, emergency exits, and assembly points to guide people to safety during evacuation.
