Types of Fire Extinguishers

Dry chemical powder fire extinguishers

The cylinder of the dry powder extinguisher is branded with a white coloured band and comes in types ABE and BE. Each type is specifically designed for multiple fire sources.

For fires fuelled by cooking oils & fats, combustible gases, flammable liquids or any types of electrical fire, the white BE extinguisher is most suitable.

For fires fuelled by combustible gases, flammable liquids, electrical fires, and class A fires (caused by carbonaceous solids like rubber, cloth, paper, wood), the ABE solution is the most potent option in this solution.     

A number of different sizes can be observed for the white banded model. For service vans, buses or small kitchens, you can even purchase a 1.5 kg extinguisher. Retail stores, kitchens, garage areas and office areas often make use of 2 kg extinguishers.

4.5 kg and 9 kg dry powder fire extinguishers are more common in areas such as fuel stations, large offices and warehouses. Aegis Safe offers fire extinguisher testing so that you can adequately maintain each device.

Carbon dioxide fire extinguishers

In case of electrical fires, the CO2 extinguishing agent is most suitable for use. A black band is used to mark this variant for ease of identification. However, the ability of the carbon dioxide extinguisher is limited when facing fires originating from other sources.

It’s better to have access to more than one type of fire extinguisher, depending on the associated risks viable at your workplace. The CO2 extinguisher is available in 3 variants, namely 5kg, 3.5kg and 2kg for workplaces susceptible to electrical fires.         

These businesses might include server or computer rooms, service bays for vehicles, welding areas and workshops. Our fire safety team offers fire services for all types of businesses.     

Wet chemical fire extinguishers

The cylinder of this device is equipped with an oatmeal striped band across it. This indicates that it is suitable for use on class A fires (carbonaceous solids) and fires caused due to hot oils and fats (class F fires). You can also opt for a 7L cylinder for larger, commercial enterprises or kitchens and a 2L one for smaller food retail enterprises.

Foam fire extinguishers

The foam fire extinguisher has a blue stripe at the top of the cylinder for identification purposes. You can utilize this device against fires caused by carbonaceous solids or flammable liquids. If you frequently deal with flammable liquids in your business, it’s highly recommended to have a blue foam fire extinguisher installed in your facility.

With the help of Aegis Safe’s frequent fire extinguisher testing, you can easily maintain your devices. Aegis Safe also offers a free reminder service that ensure our customers always remain compliant. Our highly equipped team members will provide you with details regarding your future due dates for tests, so that you can remain stress free.

Water fire extinguishers

This type of fire extinguisher has a plain red canister. It can be used for textiles, timber, and paper.

It’s crucial to avoid fires involving fuel and fires originating from electrical sources.

This type is commonly found in in businesses that deal largely with rubber, cloth, paper and timber or in educational institutions.

The effectiveness of fire protection devices is highly dependent on their maintenance. So, make sure to regularly invest in extinguisher testing services to ensure their effectiveness and functionality during an emergency.

Classes of fires

Not all fires are the same. You will only make matters worse if you use the wrong type of fire extinguisher to tackle the wrong class of fire.

Pictographs are utilized to represent various classes of fire, which help people to identify the relevant type of fire extinguishers they require. There are 6 different classes of fire we use in Australia. These are Class A, B, C, D, E and F.  

All modern fire extinguishers show these pictographs. They indicate the relevant classes of fires on which the extinguisher should be utilized.  

Normally, fires are classified based on the fuel involved. However, all fires involving energised electrical equipment are always classified under class E until the electrical circuit is disconnected. Subsequently, the fire is reclassed on the basis of the type of material that is burning.

The 6 classes of fire in Australia are:

  • Class A – Ordinary combustibles
  • Class B – Flammable liquids
  • Class C – Flammable gases
  • Class D – Combustible metals
  • Class E – Electrical equipment
  • Class F – Cooking oils and fats
Class

Description

Class AClass A fires are the most common type of fire that firefighters encounter and may be caused by clothes, rubbish bins or a pallet of cardboard. Most extinguishers, except for those using carbon dioxide, are effective against Class A fires.
Class BFires involving flammable liquids such as petrol, oil, kerosene, tar, paint or alcohol are known as Class B fires. Dry powder extinguishers are the most suitable for this type of fire and it is also possible to use carbon dioxide or foam.
Class CFires with combustible gases such as LPG (liquefied petroleum gas), butane, propane; or LNG (liquefied natural gas) and acetylene. You should only attempt to extinguish a gas fire once the gas supply has been shut down. Only a suitable dry powder extinguisher should be used.
Class D The extinguishers belonging to Class D are designed for tackling flammable metals such as aluminium, magnesium and titanium. These fires are less common as metal requires an intense amount of heat to ignite.
Class E Class E fires involve electrical equipment such as computers, heaters and fans, kitchen appliances and electronics.
Class F The extinguishers classified as Class F are most suited for fires originating from fats and cooking oils, which are usually found in kitchens. There are different ways to treat this type of fire but it’s important to make sure you never use water because it can spread the flames. A wet chemical extinguisher is the right type to use.
