Everyone is familiar with what a fire extinguisher looks like – they should be everywhere you go. However, being confident in using one is a different story. We all like to think, that in the rare occasion a fire breaks out, our heroic nature will take over and we will stop the fire with ease to rescue everyone in the building.
But in reality a fire extinguisher is actually not as lightweight as we hope, and our bravery is most likely to be swamped by fear.
The fire extinguisher has been in England since 1973 and has come a long way to look like the modern day version it is now. It’s hard to believe, but once upon a time fire-extinguishing liquid was made of gunpowder.
Nowadays, there is a fire extinguisher to help prevent every type of fire and it is important to be aware of which agent can be used for each class of fire.

Fire extinguishers can easily be purchased online. Just be sure that they are the right type and size for your premises, and that you know where to locate them. Fire extinguishers must be commissioned on-site by someone who has passed the BAFE fire extinguisher exam or has an equivalent qualification.
To comply with fire extinguisher regulations, extinguishers should be either fixed to the wall, or attached to a stand. The common water-based and CO2 fire extinguishers are usually located by exits and fire alarm call-points. ‘Specialist’ extinguishers, such as wet chemical and powder extinguishers should be positioned within easy reach of the specific fire hazard e.g. the deep fat fryer.
All extinguishers should also be clearly signposted with fire extinguisher ID signs fixed to the stand or the wall explaining which type of extinguisher they are, and how and when to use them.
Using a fire extinguisher isn’t rocket science – but by no means is it as easy as switching on the TV – so there are a few basics you need to know.
You must always ensure the fire extinguisher is safe before use, here are some top tips:
There are a variety of fire extinguishers you are likely to have seen before – in your office, local shops, or at home. Below is a guide on how to use each of the extinguishers on different types of fires they are suitable for.
Foam extinguishers allow a build up of foam across the surface of the fire, causing it to be smothered. You can make sure that the fire has been extinguished when the foam has created a blanket over the fire, preventing re-ignition.
Do not hold the horn (unless it is a frost-free horn) – it becomes extremely cold during use and can lead to severe frost burns.
Please note that a CO2 extinguisher only has a very short discharge time. Ensure all the fire has been extinguished as reignition is possible when a CO2 extinguisher has been used.
Ensure all the fire has been extinguished – reignition can be possible when a powder fire extinguisher has been used.
Fires double in size every 60 seconds – so it’s important to take note of these tips now, to prevent fumbling around in an emergency.
