FIRE EXTINGUISHER TYPES

The are many types of fire extinguishers.

The range can be very daunting and often unclear which is suitable for your needs.

It is First4Safety's job to advise you based on your local threats and environment.

Fire Extinguisher Types

ABC FEs.png

ABC Fire Extinguishers

ABC fire extinguishers are very versatile and therefore a very common choice. They are often the ideal choice being that they are able to put out many different types of fires.

BC FEs.png

BC Fire Extinguishers

BC extinguishers are termed regular or ordinary extinguishers and can be used on class B and C fires. They were the first of the dry chemical fire extinguishers developed. The powder is usually White or Blue in color.

In the heat of a fire, it releases a cloud of carbon dioxide that smothers the fire. That means the CO2 gas, which is heavier than oxygen, keeps oxygen away from the fire which then dies out.

AB Fire Extinguishers

AB fire extinguishers are applicable to Class A Fires and Class B Fires. Class A fires include ordinary materials like burning paper, lumber, cardboard, plastics etc. Class B fires include flammable or combustible liquids such as gasoline, kerosene, and common organic solvents used in the laboratory.  The units shown here are good for handling either kind of those fire threat. However, they should NOT be used on energized electrical equipment (Class C) or burning metals (Class D) fires.

WATER Fire Extinguishers

Water fire extinguishers only work on Type A fires involving flammable solids. They are a good choice for some premises, such as storage facilities and warehouses.

CO2 FEs.png

CARBON DIOXIDE Extinguishers

Carbon dioxide (CO2) extinguishers contain a mixture of liquid and gaseous carbon dioxide (a non-flammable gas). When you use the trigger and release the pressure, the gas expands rapidly and makes a huge white jet. Carbon Dioxide is heavier than oxygen so it starves the fire of oxygen.

Good for B & C fires, but NOT Class A fires due the fact that they typically hold lots of heat and can reignite once the CO2 has dispersed.

Clean Agent FEs.png

CLEAN AGENT FIRE Extinguishers

Clean Agent fire extinguishers leave no residue, require no cleanup after discharge and are safer for equipment and also for the environment.

They are designed for the protection of commercial and industrial facilities that typically contain sensitive equipment such as semiconductor fabrication facilities, food processing facilities and similar applications, electronic data or materials.

Class  K    (Kitchen) Extinguishers 

Class K fire extinguishers are mandatory in commercial kitchens.

 

They are designed to deal with the types of fires that can come  from cooking appliances and greases etc.

The active extinguishing agent is aqueous film-forming foam (AFFF.) It quickly destroys the flames and forms a vapor-securing blanket to prevent re-ignition.

D FEs.png

Class  D    (Metals) Extinguishers

Class D fire extinguishers are used on combustible metals, such as magnesium, titanium, sodium, potassium and sodium-potassium alloys, etc., which require an extinguishing medium that does not react with the burning metal.

Water should never be used to extinguish a Class D fire as it will actually serve to energize the flames, potentially spreading the fire and creating additional heat and damage. Class D is appropriate for such fires, though not a common fire class.

Purple K FEs.png

Purple K    (Oils) Extinguishers

A Purple-K dry chemical agent can be used to fight fires in flammable liquids, gases, and greases (Class B).

 

They can also be used against fires involving energized electrical equipment (Class C).

High Flow FEs.png

High Flow Fire Extinguishers

These High Flow extinguishers have a quick discharge rate. This enables the dry chemical agent to reach fires faster, providing increased firefighting capability as compared to a standard fire extinguisher.

 

They are available in ABC or Purple K agent.

Automatic FEs.png

Automatic Extinguishers

Torrent Series Automatic ABC Fire Extinguishers act fast to stop fires before they can spread and damage your assets. With discharge times of 10 seconds or less, installations benefit from fast response to the danger posed by fire.

Totally self-contained and fully automatic, the extinguishers require no external power or connections, yet they maintain fire protection around the clock, delivering years of reliable service.
