käsisammuttimille

Käsisammuttimet are portable fire extinguishers designed for manual operation. They are commonly found in homes, vehicles, and small businesses to provide immediate response to incipient fires. These devices contain a fire-extinguishing agent that is expelled under pressure when a lever or trigger is squeezed. The extinguishing agent is expelled through a nozzle or hose, allowing the user to direct it at the base of the fire.

There are several types of käsisammuttimet, each suited for different classes of fire. Water extinguishers are effective against Class A fires (ordinary combustibles like wood and paper) but should not be used on electrical or flammable liquid fires. Dry chemical extinguishers are versatile and can be used on Class A, B (flammable liquids), and C (electrical) fires. Carbon dioxide (CO2) extinguishers are best for Class B and C fires, as they displace oxygen and cool the fire without leaving a residue. Foam extinguishers are suitable for Class A and B fires.

Proper use of a käsisammutin involves remembering the PASS acronym: Pull the pin, Aim the nozzle at the base of the fire, Squeeze the lever, and Sweep from side to side. It is crucial to ensure the extinguisher is appropriate for the type of fire and to maintain a safe distance. Regular inspection and maintenance are necessary to ensure the extinguisher is fully charged and operational. Käsisammuttimet are a vital first line of defense against small fires, helping to prevent them from escalating into larger, more dangerous situations.
