If You Have Doubts

Foam fire extinguishers are suitable for use on class A solid combustible fires (wood, paper, textiles) and class B flammable liquid fires (petrol, diesel, paint, solvents).

Class A fires are generally caused by a naked flame or items of high temperatures coming into contact with combustible, carbonaceous materials.

Almost all premises are at risk of Class A fires due to the widespread use of such materials. This includes offices, schools, warehouses, hospitals, and anywhere that uses or contains paper, cardboard, wood, etc.

There are several types of fire extinguishers that can be used on Class A fires. These are powder, foam, water and wet chemical.

Class B fires occur when flammable liquids, such as petrol and spirits, are exposed to a source of ignition. These types of liquid are flammable by design and extremely volatile, if not stored safely.

Many settings, including restaurants, bars, garages, construction sites, laboratories, hospitals and petrol forecourts, are at particular risk of Class B fires and must keep suitable fire extinguishers on-site and mandatory fire safety signage to highlight the proper safety procedures of everyone onsite.

Fire extinguishers suitable for Class B fires are powder, CO2 and foam.

Class F Fires are caused by cooking oils and fats and more likely to occur within kitchens or food preparation areas.

Foam fire extinguishers display a cream label.
