Specialist Fire Extinguishers

Specialist Fire Extinguishers

A specialist fire extinguisher is a type of fire extinguisher that is designed and manufactured to extinguish specific types of fires involving particular classes of fire hazards. These extinguishers are intended for use in situations where conventional fire extinguishers may not be effective or safe. Specialist fire extinguishers are typically labelled with symbols and classifications to indicate the types of fires they are designed to combat.

There are several different types of specialist fire extinguishers, each designed for specific fire hazards.

L2 Dry Powder

L2 Dry Powder 9kg fire extinguisher is highly effective against a wide range of Class D general metal and lithium metal fires. Unlike other Class D fire extinguishers, the L2 Dry Powder fire extinguisher can tackle lithium fires which are very dangerous.

An L2 Dry Powder fire extinguisher great specialist fire extinguisher is designed to put out Class D fires. Class D fires are rare and challenging to put out. Because of this, they are not protected by standard fire extinguishers. Flammable metal fires are extremely hazardous and strong, making them difficult to put out. For this reason, this fire extinguisher must be used. The L2 fire extinguisher’s unique quality is its ability to put out lithium fires. Compared to M28 Powder fire extinguishers, which cannot put out lithium fires, this is its advantage.

These special powder extinguishers are designed specifically to fight combustible metal fires (Class D), such as sodium, magnesium and aluminium typically in the form of machined swarf or powder. 

In summary, L2 Dry Powder fire extinguishers offer significant protection over these fire risks but care should be taken to ensure you choose the correct type for your application and to be aware of their limitations.

Monnex Dry Powder

Monnex was developed for high-risk situations, making it ideal for all Class BCE fires. It’s a great solution for processing and storing flammable liquids including liquefied natural gas, hydrocarbon oils, petrol and fuel. Additionally, it works particularly well against industrial chemicals that are more difficult to eliminate with conventional dry chemical powders, such as alcohol, ketones, ethers, and esters.

A Monnex dry powder fire extinguisher is a type of fire extinguisher that contains a special dry chemical powder called potassium bicarbonate-based Monnex. Monnex is specifically designed to combat Class B (flammable liquids) and Class C (flammable gases) and Electrical fires.

Monnex Dry Powder at first glance may seem like it is just a regular Dry Powder fire extinguisher that cannot combat Class A fires. However, Monnex Dry Powder is used for higher-risk situations and can combat higher-class fires. This is where it outshines the standard Dry Powder (ABC) fire extinguishers.

Despite their many advantages, it’s important to note that Monnex Dry Powder extinguishers may not be suitable for all fire situations. They can also create a cloud of powder that may obscure visibility and make breathing difficult, so they should be used with caution in enclosed spaces. Additionally, Monnex extinguishers should be used in accordance with their specific instructions and training to ensure safe and effective fire suppression.

M28 Powder

M28 Powder fire extinguishers are similar to L2 in the fact that they can both combat Metal or Class D fires. However, the M28 Powder extinguisher cannot fight Lithium fires. Lithium fires are among some of the most dangerous and powerful types of fire.

If you are in need of a Class D fire extinguisher but you will not have to protect against Lithium fires, M28 Powder extinguishers are the extinguisher for you. Due to them not combating Lithium fires, this makes them slightly cheaper than the L2 Dry Powder extinguisher.


Specialist fire extinguishers like L2 Dry Powder and Monnex Dry Powder serve critical roles in fire safety, with specific uses and buying reasons based on their unique properties and practicalities. L2 Dry Powder extinguishers are designed for combating flammable metal fires (Class D fires), such as those involving magnesium or lithium. Their primary use is in industrial settings where these metals are present, and their high-velocity discharge effectively blankets the fire to starve it of oxygen, making them indispensable for specialised metalworking operations. 

Monnex Dry Powder extinguishers, on the other hand, excel in handling Class B and Class C fires, including flammable liquids and gases. Their quick knockdown capability and wide application range make them valuable for chemical plants, refineries, and areas with diverse fire risks.

When considering the purchase of these specialist fire extinguishers, strict safety regulations, industry-specific requirements, and the need to protect valuable assets are usually the main reasons. Industries prone to metal fires, like aerospace or manufacturing, opt for L2 Dry Powder extinguishers to meet safety standards and protect expensive equipment.

Monnex Dry Powder extinguishers, on the other hand, are favoured by sectors dealing with flammable substances, such as oil and gas, as a versatile solution to address a range of fire hazards. In both cases, purchasing decisions are guided by compliance with safety codes, risk assessments, and the specific fire risks present in the environment.

Overall, these specialist fire extinguishers play indispensable roles in safeguarding lives, property, and industrial operations by addressing unique fire risks with tailored solutions.
