Trockenpulverlöscher

Trockenpulverlöscher are a type of portable fire extinguisher that uses a dry powder as the extinguishing agent. They are effective against a wide range of fire classes, including Class A (ordinary combustibles), Class B (flammable liquids and gases), and Class C (electrical fires). The powder works by chemically interrupting the combustion process and also by forming a barrier that smothers the fire.

These extinguishers are identifiable by their distinct pressure gauge, which indicates the operating pressure, and a tamper seal on the operating lever. The powder itself is typically a fine, non-toxic substance, often based on monoammonium phosphate or sodium bicarbonate. When discharged, the powder creates a cloud that can reduce visibility, which is a consideration during use.

Trockenpulverlöscher are commonly found in vehicles, industrial settings, and public buildings due to their versatility. They are relatively simple to operate, usually requiring the user to pull a pin, aim the nozzle at the base of the fire, and squeeze the operating lever. Maintenance typically involves annual inspections to ensure the pressure is within the correct range and the powder is not compacted. They are considered a reliable and cost-effective fire suppression solution for many common fire hazards.
