Fire Extinguishers Types and Uses



Safety, outside home or inside home is very important. It is important for each and every person to get and provide safety. It gives us mental and physical support to work. Security wise if we see, many countries keep changing their measures for safety and security of their employees at workplace. It also keeps administrations or Companies away from hassles. In many countries it's mandatory for every company to have safety Instruments and measures and if not it leads to fines. There are many instructions and equipment for safety and security. Basic safety measures should be everywhere, from small to big enterprises. But, according to business or organization, extra important items get added to their safety measures.


One of the main safety equipment is Fire Extinguishers. A fire extinguisher is an active fire protection device used to extinguish or control small fires, often in emergency situations. Typically, a fire extinguisher consists of a hand-held cylindrical pressure vessel containing an agent that can be discharged to extinguish a fire. Fire extinguishers manufactured with non-cylindrical pressure vessels also exist but are less common.

Fire Extinguishers are something which should be everywhere. We all are always exposed to great towers, electrical wires etc. Any internal damage without knowledge of it can create big accidents.

So, one always needs to be careful whether at home or workplace.

So, there is a lot about Fire Extinguishers. One should always keep these points in mind.


Types and Uses of Fire Extinguishers

There are basically two main types of fire extinguishers:

Stored-pressure and cartridge-operated


In stored pressure units, the expellant is stored in the same chamber as the firefighting agent itself. Depending on the agent used, different propellants are used. With dry chemical extinguishers, nitrogen is typically used; water and foam extinguishers typically use air. Stored pressure fire extinguishers are the most common type.






Cartridge-operated extinguishers contain the expellant gas in a separate cartridge that is punctured prior to discharge, exposing the propellant to the extinguishing agent. This type is not as common, used primarily in areas such as industrial facilities, where they receive higher-than-average use. They have the advantage of simple and prompt recharge, allowing an operator to discharge the extinguisher, recharge it, and return to the fire in a reasonable amount of time.


Fire extinguishers are available in different types with each one having specific fire classes that they are suitable for use on.


Wet Chemical: Wet Chemical fire extinguishers are designed specifically for use on fires involving combustible cooking media such as burning oil and fat. They have a class F rating and a special lance applicator nozzle. They usually have an additional class A rating and are normally not designed for use on class B fires (petrol, diesel, paint, paraffin etc), although the 3ltr Gloria wet chemical fire extinguisher is an exception.






ABC Powder : ABC powder fire extinguishers are extremely versatile and can be used on class A, class B, class C and electrical fires. They are available in a range of sizes from 1 - 9kg and are ideal for application in environments containing mixed fire risks. However, there is a risk of inhalation when using powder extinguishers indoors. Powder fire extinguishers are therefore not recommended for use within small rooms, homes and offices.









How to Choose the Fire Extinguishers?

This all depends on type of work any industry or company is doing. Based on its intended location of use, and any specific hazards that may exist there.

The most common, and the most likely to be proper for you, is the class ABC (explained below) dry chemical extinguishers around. These spray a powdered firefighting agent out when used.

They are suitable for use on the following classes of fires:

A- wood/paper

B- flammable liquids (oil/gasoline)

C- electrical
