CSCS - Construction Skills Certification Scheme Fire Safety and Emergency Questions and Answers

Question 1

For a fire to start and continue to burn, three components are required, often known as the 'fire triangle'. What are these three essential components?

Accepted Answer

Oxygen, Heat, and Fuel

Answer

The fire triangle illustrates the three fundamental elements needed for combustion: a source of fuel (something to burn), a source of heat (an ignition source), and oxygen (to sustain the reaction). Removing any one of these elements will extinguish a fire.

Question 2

You see flames coming from a temporary electrical distribution board on a construction site. Which type of fire extinguisher is the most appropriate and safest to use?

Accepted Answer

CO2 (Black label)

Answer

CO2 extinguishers are designed for fires involving live electrical equipment as the carbon dioxide is non-conductive and leaves no residue. Using water on an electrical fire is extremely dangerous as it can cause electrocution.

Question 3

Which of the following is a critical legal requirement for fire escape routes on a construction site?

Accepted Answer
