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 FPAA classification of fires, there are 6 different types or classes of fires and each has a specific type of fire extinguisher.
Classes of Fire
|Class A Fires – Fueled by wood, paper or other ordinary combustible solids (including cloth, plastics, rubber, coal, carbon based compounds etc)|
|Class B Fires – Involving flammable & combustible liquids such as grease, gasoline, oil, paint, thinners, kerosene, alcohol, etc|
|Class C Fires – Involving flammable gases, such as
LPG, Butane, Acetylene, Hydrogen, natural gas, Methane, etc
|Class D Fires – Involving combustible metals, like magnesium, aluminium, sodium, potassium etc|
|Class E Fires – Electrically energised (computers, switchboards, power-boards, etc)|
|Class F Fires – Involving cooking oils and fats (most commonly occur in industrial kitchens)|
Fire safety is all about vigilance and preparation. Ceasefire provides different fire extinguishers to put out all 6 different classes of fires as outlined by the FPAA. Here is a list of some of our offerings as well as a description of the fires they extinguish 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 and class E fires by displacing oxygen in the air preventing a fire from burning. This type is especially good for electronic fires
- Foam extinguishers – Effective on different classes of fire due to the versatile properties of foams. It can dampen the fuel source or smother making it a must around kitchens and other areas dealing with flammable liquids
- Dry powder extinguishers – Even more versatile due to the unique powder agent this type can take care of most Class A-F fires
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.
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.
Fire extinguisher maintenance
All extinguishers have to be inspected at six monthly intervals and if they don’t have a pressure gauge, they may need to be weighed to check they are still full. Some extinguisher types may require additional tasks to be carried out annually. Extinguishers need to be emptied, pressure tested and refilled every six years (AS1851-1995). There may be other servicing requirements at 3, 5 or 6 years. This can be done by a registered fire extinguisher service organisation, such as Ceasefire.
If an extinguisher is discharged, even partially, it needs to be refilled by a registered fire extinguisher service organisation.
