Question 2

What are the three elements of the fire triangle?

The fire triangle consists of heat (ignition source), fuel (combustible material), and oxygen (air). Removing any one of these elements will prevent a fire from starting or cause it to go out.

Question 3

What class of fire involves flammable liquids?

Accepted Answer

Class B

Answer

Class B fires involve flammable liquids such as petrol, diesel, oil, paint, and solvents. Different extinguisher types are effective on different classes — foam and CO2 extinguishers are suitable for Class B fires.

Question 4

What type of fire extinguisher should NOT be used on electrical fires?

Accepted Answer

Water extinguisher

Water extinguishers must never be used on electrical fires as water conducts electricity, creating a risk of electrocution. CO2 and dry powder extinguishers are safe for use on electrical fires. The power should be isolated if possible.

Accepted Answer

Annually by a competent person, with a more detailed extended service at specific intervals

Answer

Under BS 5306-3, fire extinguishers must receive an annual basic service by a competent person. Extended services are required at specific intervals depending on the extinguisher type (e.g., every 5 years for water and foam).
