Pulversläckmedel

Pulversläckmedel, often translated as dry powder extinguisher, refers to a type of fire extinguisher that expels a powdered chemical to extinguish fires. These extinguishers are versatile and effective on a range of fire classes, including Class A (ordinary combustibles), Class B (flammable liquids), and Class C (flammable gases). Some formulations are also suitable for Class D fires involving combustible metals, though specialized powders are used for these.

The extinguishing agent in these devices is typically a fine powder such as monoammonium phosphate, sodium bicarbonate, or potassium bicarbonate. When discharged, the powder smothers the fire by forming a barrier between the fuel and oxygen, and in some cases, it interrupts the chemical chain reaction of the combustion process.

Pulversläckmedel are characterized by their ease of use and their ability to suppress fires quickly. However, they do have drawbacks. The powder can be messy and difficult to clean up, and it can obscure vision in smoky environments. Inhalation of the powder should also be avoided. It is important to note that while effective, pulversläckmedel are not ideal for use in enclosed spaces where the dispersal of powder could pose respiratory hazards. Regular maintenance and inspection are crucial to ensure their operational readiness.
