Käsisammuttimen

Käsisammutin, commonly known as a portable fire extinguisher, is a crucial piece of firefighting equipment designed for initial intervention in small fires. These devices are typically handheld and contain a specific extinguishing agent that is discharged under pressure to suppress or extinguish a fire. The type of extinguishing agent used depends on the class of fire it is intended to combat.

Fire extinguishers are classified into categories based on the types of flammable materials they can effectively extinguish. These classes include Class A (ordinary combustibles like wood and paper), Class B (flammable liquids like gasoline and oil), Class C (electrical fires), Class D (combustible metals), and Class K (cooking oils and fats). Different agents are suitable for different classes, for example, water is effective for Class A fires but can spread Class B fires and is dangerous on electrical fires.

Common extinguishing agents include water, foam, dry chemical powder, and carbon dioxide. Dry chemical extinguishers are widely used due to their versatility across multiple fire classes. Carbon dioxide extinguishers are often used for electrical fires as they leave no residue. Foam extinguishers are effective for Class A and B fires. Regular inspection and maintenance are essential to ensure a käsisammutin is in good working order and ready for use in an emergency.
