Description

4kg dry powder fire extinguisher is a versatile fire safety device designed to combat various types of fires. It can be used on fires involving solid combustibles, flammable liquids, and electrical equipment.

It works by disrupting the chemical chain reaction of the fire. In addition, it cuts off the oxygen supply, effectively smothering the flames.

These extinguishers are commonly used in garages, workshops, and areas with flammable liquids or gases.

4kg dry powder fire extinguisher Key Features and Characteristics:

Extinguishing Mechanism

The dry powder smothers the fire by creating a barrier between the fuel and the oxygen, and it also interferes with the chemical reaction of the fire.
Potential Drawbacks

Dry powder extinguishers can be messy, and the residue can be harmful if inhaled or if it gets into sensitive electronics.

They are also not recommended for use in enclosed spaces where visibility could be severely reduced.
Temperature Range

They can typically operate in a wide range of temperatures, often from -30°C to +60°C.
Pressure

The typical operating pressure is around 14 Bar, with a test pressure of 25 Bar.
Compliance

Many dry powder extinguishers are manufactured to meet European standards like EN 3 P.E.D “CE”.
Additional Considerations

Specialized dry powder extinguishers are used for fires involving flammable metals like titanium and magnesium.
In summary, a 4kg dry powder fire extinguisher is a useful tool for a variety of fire risks, but it’s important to be aware of its potential drawbacks and limitations, particularly regarding enclosed spaces and sensitive equipment.
