Fire Extinguisher

Description

Key features and components of a typical fire extinguisher include:

1. Cylinder: The main body of the fire extinguisher is a cylindrical container usually made of metal, such as steel or aluminum. The cylinder houses the extinguishing agent and is designed to withstand pressure.
2. Pressure Gauge: Fire extinguishers often have a pressure gauge on the cylinder, indicating the level of pressure inside. It helps determine whether the extinguisher is fully charged and ready for use.
3. Handle and Nozzle: The handle, usually located on the top of the extinguisher, allows for easy carrying and operation. The nozzle, positioned at the end of a flexible hose or pipe, directs the flow of the extinguishing agent toward the fire.
4. Extinguishing Agent: Different types of fire extinguishers contain specific extinguishing agents suitable for various fire classes. Common extinguishing agents include water, foam, dry chemical powder (ABC or BC), carbon dioxide (CO2), and clean agents like halon alternatives or clean agents like halotron or FM-200.
5. Fire Classifications: Fire extinguishers are categorized into different classes based on the type of fire they are effective against. The classes are as follows:
   • Class A: Fires involving ordinary combustible materials like wood, paper, cloth, or plastic.
   • Class B: Fires fueled by flammable liquids such as gasoline, oil, or paint.
   • Class C: Fires involving energized electrical equipment, such as appliances or electrical panels.
   • Class D: Fires caused by combustible metals like magnesium, titanium, or sodium.
   • Class K: Fires in commercial kitchens involving cooking oils and fats.
6. Operating Instructions: Fire extinguishers usually have clear operating instructions printed on their body, including how to activate them, how to aim at the base of the fire, and when to use them.
