Palonsammuttimilla

Palonsammuttimilla, commonly referred to as fire extinguishers, are portable devices used to suppress or control small fires. They work by expelling a material that smothers the fire, cools the burning material, or interrupts the chemical reaction of combustion. The effectiveness of a fire extinguisher depends on the type of fire it is designed to combat and the extinguishing agent it contains.

Fire extinguishers are classified based on the types of fires they can extinguish. Class A fires involve ordinary combustibles like wood, paper, and cloth. Class B fires involve flammable liquids and gases such as gasoline and propane. Class C fires involve energized electrical equipment. Class D fires are for combustible metals like magnesium and titanium. Class K fires involve cooking oils and fats. Different extinguishing agents are used for each class, including water, foam, dry chemical, carbon dioxide, and wet chemical.

The operation of most fire extinguishers follows the P.A.S.S. acronym: Pull the pin, Aim the nozzle at the base of the fire, Squeeze the handle, and Sweep from side to side. Regular inspection and maintenance of fire extinguishers are crucial to ensure they are functional when needed. This includes checking the pressure gauge, ensuring the pin and tamper seal are intact, and verifying the unit has not been damaged. Training on the proper use of fire extinguishers is highly recommended for individuals who may encounter fire emergencies.
