A foam extinguisher is a firefighting tool that uses an expanding, high-foaming agent to smother and suppress fires. Foam can be used on Class B (flammable liquid) or Class C (electrical) fires. It works by forming a blanket of foam over the fuel source, which prevents oxygen from reaching it and thus suffocating the flame.

Foam Extinguisher: Frequently asked questions

What types of Foam Extinguisher are there and what determines a good product?

There are two types of foam extinguishers, AFFF and CAFS. The difference between the two is that AFFF uses fluorocarbons as a fire suppressant while CAFS uses ammonium phosphate ester to do so. Both have excellent performance in fighting Class B fires (flammable liquids) but only AFFFs can be used on electrical equipment such as computers or televisions because they don’t conduct electricity like water does.

The quality of the foam extinguisher is determined by its ability to produce a stable, uniform blanket of fire-extinguishing foam. This depends on several factors such as nozzle design and propellant type.

Who should use a Foam Extinguisher?

Anyone who can read and follow the instructions on a fire extinguisher. This includes everyone from children to seniors, as long as they are physically able to use it. You should also be familiar with how your specific type of foam works before you need it in an emergency situation.

Based on what criteria should you buy a Foam Extinguisher?

Foam extinguishers are used to fight class A, B and C fires. They should be selected based on the type of fire you wish to put out. For example, if your business is in a warehouse that contains flammable liquids or gases then you will need an ABC foam extinguisher which can handle all three types of fires (class A, B & C). If however it is just wood/paper products that are burning then a Class D dry chemical extinguisher would suffice for this situation as they only work with combustible metals such as magnesium and potassium etc..

The first thing you should look out for is the size of the Foam Extinguisher. You need to make sure that it will fit in your car, otherwise there’s no point buying one. Also, check how much foam comes out of each squirt and whether or not it can be adjusted. Finally, if possible try before you buy as this way you get a feel for what type of extinguisher works best with your needs.

What are the advantages and disadvantages of a Foam Extinguisher?

Advantages

Foam extinguishers are ideal for fighting Class A fires. They can be used on electrical equipment, wood and paper products as well as liquids such as oil or gasoline. The foam will not damage the surface of materials so it is safe to use in sensitive areas where water may cause more harm than good.

Disadvantages

Foam extinguishers are not effective on Class B fires, such as flammable liquids. They also have a limited range and do not work well in windy conditions.
