What color is a foam fire extinguisher

The fire extinguishers used for flammable liquids, such as class B fires, are known as foam fire extinguishers. These extinguishers are water based so that’s why they are also used for class A fires.

These extinguishers are used for a cooling effect and also help to smooth the flame, used by most of the renowned businesses for safety. These extinguishers are also known as AF foam extinguishers.

Extinguishers are usually in red; this fire extinguisher is cream-colored. This color helps to identify the extinguisher.

A foam word is stated on the cream-coloured label printed body of these extinguishers. These extinguishers are also identified by the ID assigned to them.

This type of extinguisher is available in different sizes.

• 2liter
• 3liter
• 6liter
• 9liter

Mostly 6-liter extinguishers are used for any accident that happens due to flammable liquids.

This extinguisher is used for fires that happen due to flammable liquids, class B type, and also used for class A type flammable solids. This Fire extinguisher passed a conductivity test of 35kv for fires that happen due to electrical appliances IF. Explicitly, this extinguisher is not designed for use on electric fires.

Using a fire extinguisher on an electrical fire causes electric shock, that’s why a 35k conductivity test is being done for additional safety measures. For electric fire use dry powder and CO2 extinguisher.

• Please do not use it for fires involving grease and oil, such as fire C class. In homes, mostly, these fires are chippan fires.
• Please do not use it for fires involving flammable gases, such as fire F class. These gases are methane and butane. 

These extinguishers are working in two different ways to lower down fires.

• Firstly, they lower the temperature because they are water-based. They put the fire out and give the cooling effect.

• Secondly, this extinguisher has an element AF, which is also known as an “Aqueous Film Forming Foam.

These fire extinguishers are non damageable to most things or materials. These extinguishers are lighter in weight than other extinguishers.

These extinguishers damage electrical appliances and are dangerous in flammable gas fires.

Extinguishers are really important for the places where risk is high, such as

• Hotels 
• Garages 
• Warehouses 
• Factories
• Offices

These extinguishers are used differently based on the type of fire.

Flammable liquids fires

• Never spray directly at the fire because spray spreads to other surfaces that are located nearby.
• if the liquid on the fire is present, then spray directly at the liquid.
• If the liquid is not present on the surface, then spray on the adjacent or top surface.
• By applying this, the foam will cool down the burning liquid.

Flammable solids fires

• Focus on the point where fire is present.
• When you spray at the flames, keep moving the extinguisher.

Electrical fires (not recommended)

• Follow as like solids fire procedure
• Stay 1m away from the incident for the safety of yourself.

Traditional AF extinguishers are harmful to the environment, human health and the ecosystem. Safelincs phase out these extinguishers. Now, they are substituted by water mist extinguishers.

Foam fire extinguishers are used for A and B-type classes. They are suitable for high-risk places but do not use grease, electrical and flammable fires.
