Fire Extinguisher
What is Fire Extinguisher ?
A fire extinguisher is a device used to put out or control small fires, often in emergency situations. It works by releasing a substance that either cools the burning material, removes oxygen, or disrupts the chemical reaction of the fire.
Types & Classes of Fire Extinguisher
Water Extinguisher
Effective on Class A fires (wood, paper, cloth). They cool the burning material.
Foam Extinguishers
Suitable for Class A and B fires (flammable liquids like gasoline). They form a foam blanket that smothers the fire and prevents re-ignition.
Carbon Dioxide (CO2) Extinguishers:
Good for Class B and electrical fires. They work by displacing oxygen and cooling the fire.
Dry Chemical Extinguishers
Versatile and effective on Class A, B, and C fires (electrical fires). They interrupt the chemical reaction of the fire.
Wet Chemical Extinguishers
Designed for Class K fires (kitchen fires involving cooking oils and fats). They work by forming a soapy layer that cools and prevents re-ignition
