Powder Fire Extinguishers

Dry powder fire extinguishers, also known as ABC extinguishers, are filled with a fine, phosphate-based powder like monoammonium phosphate. This powder acts as a smothering agent, coating the fuel and interrupting the chemical reaction of fire. Nitrogen gas is used to pressurise the extinguisher, allowing for quick and forceful discharge of the powder when needed. Some extinguishers may also contain additives like silicon to improve the powder’s flow and prevent clumping.

Dry powder fire extinguishers are multi purpose which mean they are suitable for use on Class A (burning paper, wood, fabric), Class B fires (flammable liquids like gasoline), and Class C fires (electrical equipment). It is important to take care when using powder fire extinguishers, as once discharged, they will leave a lot of residue.

Like the other types of extinguishers we stock, Dry Powder fire extinguishers are available in traditional red and chrome finishes, however blue labelling indicates that it is a a powder fire extinguisher. The main reason that there is an international standard for the colour of fire extinguishers is so that anyone tackling a fire can be sure they are using the right tools for the job.

A dry powder fire extinguisher gets right to the heart of the fire oxygen! Packed with a fine, phosphate-based powder like monoammonium phosphate, it disrupts the fire triangle at two crucial points: First it smothers the Fire: When discharged, the powder forms a thick cloud that blankets the fuel, effectively cutting off its oxygen supply. This suffocates the flames, hindering their ability to burn. The powder doesn’t just block oxygen; it also interferes with the chemical chain reaction that sustains the fire. This is what makes dry powder extinguishers highly effective against Class A (wood, paper, fabric), Class B (flammable liquids), and Class C (electrical equipment) fires. However, remember that the powder residue can be messy and difficult to clean up, so use it strategically!

To use a dry powder fire extinguisher, follow the P.A.S.S. acronym: Pull the pin. Aim the nozzle at the base of the fire. Squeeze the handle to release the powder. Sweep the nozzle from side to side, covering the fire until it’s fully extinguished. This straightforward process ensures effective deployment in emergency situations.

Dry powder fire extinguishers come in various sizes to accommodate different fire risks and environments. Common sizes include 1 kg, 2 kg, 4 kg, 6 kg, and larger options for industrial use. Choosing the appropriate size depends on factors such as the potential fire hazard and the size of the area to be protected.

Dry powder fire extinguishers are strategically located in areas where diverse fire risks exist. Common placements include kitchens, workshops, garages, and industrial settings. They are especially suitable for locations with mixed fire hazards, such as those involving flammable liquids, gases, and electrical equipment, due to their versatile multi-class capability.
