Fire Extinguisher

A fire extinguisher is a portable firefighting device designed to control or extinguish small fires. It is a crucial safety tool commonly found in homes, workplaces, public buildings, and vehicles to help individuals respond quickly to fire emergencies before they escalate.

Key components of a typical fire extinguisher:

  1. Cylinder: The main body of the fire extinguisher, usually made of metal, contains the extinguishing agent and propellant.

  2. Nozzle/Valve: The nozzle or valve is the outlet through which the extinguishing agent is released when the fire extinguisher is operated.

  3. Pressure Gauge: Many fire extinguishers have a pressure gauge to indicate the pressure level of the extinguishing agent inside the cylinder. This helps ensure the fire extinguisher is charged and ready for use.

  4. Safety Pin: To prevent accidental discharge, fire extinguishers often have a safety pin or tamper seal that needs to be removed before use.

  5. Handle/Trigger: The handle or trigger is used to activate the fire extinguisher and release the extinguishing agent onto the fire.

Types of Fire Extinguishers:

There are different types of fire extinguishers, each designed to combat specific classes of fires. The most common types are:

  1. Class A: Designed for fires involving ordinary combustible materials like wood, paper, cloth, rubber, and plastics.

  2. Class B: Suitable for flammable liquid fires, such as gasoline, oil, grease, and solvents.

  3. Class C: Used for fires involving electrical equipment and appliances.

  4. Class D: Intended for fires involving combustible metals like magnesium, titanium, potassium, and sodium.

  5. Class K: Specifically designed for kitchen fires involving cooking oils and fats.
