Powder Fire Extinguishers
Versatile, reliable, and powerful, powder fire extinguishers are among the most effective solutions for dealing with a wide range of fire types.
What are powder fire extinguishers?
A powder fire extinguisher works by releasing a fine chemical powder under pressure, which rapidly suppresses flames and interrupts the chemical reaction that sustains combustion. The powder forms a barrier between the fuel and oxygen, effectively smothering the fire and preventing it from reigniting.
They’re generally not recommended for use in enclosed indoor spaces, as the fine powder can reduce visibility, leave residue, and may affect sensitive equipment or machinery.
The extinguishing agent used in dry powder fire extinguishers can vary depending on the application, for example:
- Standard dry powder, also known as ABC powder, is suitable for most common fire types.
- Specialist powders, such as Monnex or L2, are designed for specific hazards, including flammable metals or industrial processes.
The fire classes that are suitable for a powder fire extinguisher include:
- Class A: Fires involving solid combustibles like wood, paper, and textiles.
- Class B: Fires involving flammable liquids such as petrol, oil, and solvents.
- Class C: Fires involving flammable gases such as propane or butane.
In addition, dry powder fire extinguishers can be used on electrical fires, provided the equipment is within the manufacturer’s voltage limits.
Because of these characteristics, powder extinguishers are particularly effective in environments with mixed or unpredictable fire risks, such as:
- Industrial facilities and manufacturing plants
- Fuel storage and transport depots
- Vehicle workshops and garages
- Agricultural sites and machinery areas
- Outdoor plant, construction, and maintenance zones
Their robust performance and wide fire classification make dry powder fire extinguishers a preferred choice for outdoor and industrial settings, where versatility and immediate suppression are key.
