Fire Extinguishers

Portable fire extinguishers are an effective means of combating small fires with an aim to clearing the way out of a building or stopping a small fire from growing larger. There are several different types of fire however, and choosing the right type of extinguisher is of the utmost importance.

Class of Fire vs/ Type of Extinguisher Guide Chart

Having these measures in place can prove vital to protecting your staff, assets, and property. Hover over the images below to learn more about the types of extinguishers.

Water Spray

The water spray operates by cooling the fire's fuel to prevent it from continuing to burn, making it ideally suited to Class A fires.

Carbon Dioxide

The Carbon Dioxide works by filling a localized area with Co2 to displace the oxygen the fire needs to burn and is most effective against electrical fires.


The foam extinguisher is for use on enclosed liquid fires. This is because the foam hardens after it has left the extinguisher, creating a shell to smother the fire out.


A very effective extinguisher, the powder within the extinguisher settles in the fire to disrupt the access to oxygen, thereby smothering the fire.

Wet Chemical

A specialised extinguisher, the Wet Chemical is mainly used within kitchens for fat and oil fires. This extinguisher operates by interfering with the chemical reaction within the fire to put it out.

Fire Blanket

A more manual fire extinguishing solution, the fire blanket is simple and effective. It is designed for small enclosed fires, such as a chip pan fire, and it smothers the fire by stopping the flow of oxygen.

Just as important as having portable fire extinguishers available on site is ensuring that they are correctly maintained. Several risks are present if fire extinguishers are not maintained including:

  • Internal corrosion which can lead to unit explosion upon activation of the extinguisher

  • The hose/horn seal may deteriorate which could lead to leakage and a resulting lack of pressure if the extinguisher has to be operated, reducing its effectiveness dramatically

  • The unit may be over or under pressure which could result in too weak a flow or could potentially explode

  • Hose/horn blockages could mean that the extinguisher will not activate properly and could potentially reduce the effectiveness of the extinguisher

These are some risks which can be avoided with a maintenance regime in place.

Annual servicing is the best maintenance plan for portable fire extinguishers to cover your business.
