Fire extinguishers come in many shapes and sizes and use different materials to put out fires. However, these differences exist to combat the different types of fires that can occur. Under FPA classification of fires there 6 different types or classes of fires and each has a specific type of fire extinguisher.
> Class A fires - these are fires that are fuelled by wood or paper.
> Class B fires - fires involving flammable liquids such as grease or gasoline
> Class C fires - fires involving flammable gases
> Class D fires - fires involving flammable metals
> Class E fires - electrically energized fires
> Class F fires - fires involving cooking oils and fats
Fire safety is all about vigilance and preparation so our company provides different fire extinguisher s to put out all 6 different classes of fires as outlined by the FPAA. Here is a list of some of our offerings the fires they put our most effectively.
Air-Water Fire Extinguishers – puts out most class A fires by discharging to water to dampen the burning fuel
CO2 extinguisher puts out class B fires by displacing oxygen in the air preventing a fire from burning. This type is especially good for electronic fires
Foam extinguishers are effective on different classes of fire due to the versatile properties of foams. It can dampen the fuel source or smother making iit a must around kitchens and other areas dealing with flammable liquids
Dry powder extinguishers are even more versatile due to the unique powder agent this type can take care of most Class A-F fires.
Subtypes among common models of Fire Extinguishers
Foam and Chemical Fire extinguishers are two types of extinguishers that can utilize different discharge materials to put out fires. Foam extinguishers use either a sodium bicarbonate based foam or an mono ammonia phosphate based foam. The difference is normally negligible but can be important in the effective of the extinguisher or the personal preference of a less toxic extinguisher. Chemical fire extinguishers also have the same issues.
Effective types of Fire Extinguishers for Electrical Fires
Electrical fires have the added hazard of the potential for electrocution while extinguishing it. For this reason our company offers a line of extinguisher models made specifically to fight electrical fires. Here are two of our main models
Air Water Fire Extinguishers: This type uses de-ionized water which reduces risk of electrocution
Foam Fire Extinguishers: Foam extinguishers are multipurpose and due to its insulating properties are perfect for dealing with an electrical fire.
Some fires are so dangerous and volatile they need special extinguishers to put them out. This is especially true of fires started by combusting chemicals that may be toxic in nature or will only become more volatile if more common purpose extinguishers are used.
Extinguishers need to be pressure tested every six years. This can be done by a registered fire extinguisher service organisation.
If an extinguisher is discharged, even partially, it needs to be refilled by a registered fire extinguisher service organisation
