…fire extinguishers aren’t exciting. However, as a responsible person at a premises, under the Fire Safety Order you have a duty to plan for an emergency, as well as providing employees with information, fire safety instruction, and training.
So how do you decide what fire extinguisher(s) you will need to maximise your safety, and comply with the law? In this article, we break it all down for you.
There are 5 main types of fire extinguishers available, each serving a different purpose:
These can be identified by their red labels. They work by simply spraying a water additive from the nozzle, extinguishing the fire by soaking the burning materials. These are the most common fire extinguishers and the least hazardous, as they contain no harmful chemicals. Due to their contents, they cannot be used on electrical fires, burning oils or fats, burning metals, or flammable liquids.
These extinguishers, displaying a cream label, work by smothering the fire with a layer of foam, starving it of oxygen. They are more versatile than water extinguishers, and cost the same, although they do leave behind a residue.
Powder extinguishers feature a blue label, and form a crust which smothers the fire and stops it from spreading. However, due to the potential risks to health if inhaled, powder extinguishers must not be used in confined spaces or well-populated areas such as offices or residential premises. Like foam extinguishers, they also leave behind a lot of residue.
A black label signifies a CO2 extinguisher, which contains only pressurised carbon dioxide. They leave little residue and do not damage electrical items or computer equipment, meaning they are a practical solution for offices or hospitals.
These extinguishers display a yellow label, and are often found in kitchens where the risk of burning fats or oil is high. The chemical referred to in the name is a salt solution which, when sprayed, forms a fine mist and cools the fire while preventing any splashes. These extinguishers also come with a longer hose with a ‘lance’ attachment.
Unfortunately, there is no one-size-fits-all extinguisher that can be used on every type of fire. There are six different categories of fire, commonly referred to as classes, based on substances or materials involved. The various classes require different approaches for safe extinguishing:
