Does your business have the correct fire extinguishers

When it comes to ensuring your business is safe from fire and compliant with fire safety regulations, there are a number of factors you need to consider. One of the most important aspects for business owners is having the correct fire extinguishers on their premises. There are a number of different extinguishers available, and it’s crucial the correct type of unit is present to deal with the risks that exist in your particular workplace.

Before understanding the different extinguishers, it’s important to recognise the types of fire so the responsible person knows how to safely deal with the situation.

Different Types of Fires

Class A: A fire involving ordinary combustibles such as wood, paper, cloth, straw, and plastics.
Class B: Fires which involve flammable liquids such as gasoline, petroleum oil and paint. Class B fires can also include flammable gases like propane and butane.
Class C: Fires involving electrical equipment such as motors, transformers and appliances. If the power is removed, though, a Class C fire changes to one of the other classes.
Class D: Fires in combustible metals like potassium, sodium, aluminium and magnesium.
Class F: Fires involving cooking oils and greases such as animal and vegetable fats

Different Type of Extinguishers

There are five main types of fire extinguisher you should be aware of, each designed to cope with a specific fire hazard, with some capable of being used on more than one type of fire.  
Water: A water fire extinguisher is used for the most common Class A fires. These extinguishers are NOT suitable for any fires where either liquid or electricity is involved. 
Foam: A foam extinguisher can be used on fires where wood, straw or paper is involved as well as tackling fires started by flammable liquid. While not recommended for electrical fires, foam is safer than water if accidently coming into contact with live electrical apparatus.
CO2: Carbon dioxide extinguishers are often found where electrical fires could occur, also capable of tackling flammable liquids and other Class B fires.
Powder: A powder extinguisher is suitable for a number of different types of fires making it ideal for premises where a range of fires could start, from flammable liquids to gas or electric, as well as Class A fires.
Wet Chemical: A wet chemical extinguisher is designed specifically for fires involving cooking oil and fat, but it is also effective with Class A fires.
