CSCS Mock Test – Fire Extinguishers

Fire kills and injures many people every year in the UK. On construction, demolition or refurbishment sites there can be a high risk of fire. Smoke and fire can spread rapidly and this risk can increase depending on the stage of the project. It is therefore important that you’re familiar with the various types of fire extinguishers – not only will it appear in your CSCS Test but you may also need to use one in the event of a fire.

Fire Extinguishers Types and Colours

When using portable fire extinguishers it is vital that everyone is vigilant and any hot work is controlled. The table below shows the types of portable fire extinguishers and what to use them on.

Extinguishing medium Colour of panel Where not to use
Water: for wood, paper, textile and solid material fires
Red
Do not use on liquid, electrical or metal fires
Foam: for liquid fires
Cream
Do not use on electrical or metal

fires

Powder: for liquid and electrical fires

Specialist dry powders: for metal fires

Blue
Do not use on metal fires unless

M28 or L2 text is printed on extinguisher, which means it is suitable for metal fires

Carbon dioxide: for wood, paper, textiles, gaseous, liquid and electrical fires
Black
Do not use on metal fires
Wet chemical: for wood, paper, textile, cooking oil and solid material fires
Yellow
Do not use on liquid, gas or electrical fires

Note: dry powder extinguishers may be provided as well as or substituted for water, foam or carbon dioxide extinguishers. Extinguishers used to control Class 8 fires (flammable liquids) will not work on Class b fires (cooking oils) because of the high temperatures produced.

Fire extinguishers should only be used on very small fires (as a guide, no bigger than a waste paper bin) or to aid escape.

If you have to leave the location of the fire to raise the alarm, do not return to the fire – continue your own evacuation. Fires can spread very quickly
