Fire Extinguishers are an essential for any workplace, with different types of extinguisher capable of tackling different classes of fire.
There are five official types of fire which fire extinguishers are then measured against to test their effectiveness fighting each one.
- Class A fires involve solid materials including textiles, wood and paper
- Class B fires involve flammable liquids such as petrol, diesel or oils.
- Class C fires involve flamable gases including hydrogen or methane
- Class D fires involve combustable metals such as potassium and magnesium
- Class F fires involve cooking oils, often an issue with deep-fat fryers
Although there is not an official class for it, fires involving electrical equipment should also be taken into account. This can include computers, generators and more but only applies whilst they are plugged in. Once unplugged their classification will change based on the material the object is made from.
Types of Fire Extinguisher
We have two different types of fire extinguisher on offer here, each of them appropriate for tackling different classes of fire.
A Powder Fire Extinguisher is often refered to as an 'ABC' Extinguisher because it is designed for tackling Class A, B & C fires. It is also capable of smothering small electrical fires but as it does not cool the area down the fire may reignite. They are easily identified as they clearly state on the front which type they are and use a blue label to also help distinguish them. The biggest benefit of Powder Extinguishers is their versatility as they can effectively tackle 3 of the most commonly occuring types of fire. The disadvantage of the powder is that it can often cause loss of visibility and is easily inhaled if used in an enclosed space.
We also offer carbon dioxide or CO2 fire extinguishers. These are specifically designed for use on class B fires involving flammable liquids and electrical fires. Often these kinds of products can be found in rooms with a lot of electrical equipment such as server rooms and offices. These extinguishers have clear black labels to indicate which type they are. Their benefit over other types is that they leave no residue, using carbon dioxide to smother the fire and cut off the air supply.
