A fire extinguisher is a portable device that can be used to extinguish a fire. It contains an extinguishing agent, such as water, foam, powder, or carbon dioxide, that is released under pressure. Fire extinguishers are classified by the type of fire they are designed to extinguish.
The most common types of fire extinguishers are:
- Type A: For ordinary combustibles, such as wood, paper, and cloth.
- Type B: For flammable liquids, such as gasoline and oil.
- Type C: For electrical fires.
- Type D: For flammable metals, such as magnesium and titanium.
- Type K: For cooking media fires, such as grease and oil.
It is important to choose the correct type of fire extinguisher for the type of fire you are trying to extinguish.
To use a fire extinguisher, follow these steps:
- Pull the pin. This will release the locking mechanism and allow you to discharge the extinguisher.
- Aim low. Point the nozzle at the base of the fire.

Continue to discharge the extinguisher until the fire is out.
Here are some safety tips to keep in mind when using a fire extinguisher:
