How to control fire extinguisher in the laboratory?

1. Familiarize yourself with the type of fire extinguisher in the laboratory. There are different types of fire extinguishers for different types of fires (e.g. Class A, B, C, D, or K). Make sure you know which type is appropriate for the specific hazards in your laboratory.

2. Pull the pin or safety clip from the handle of the fire extinguisher to break the tamper seal.

3. Aim the nozzle or hose at the base of the fire, not at the flames. This will help to smother the fire by cutting off its oxygen supply.

4. Squeeze the handle or trigger to release the extinguishing agent. Use a sweeping motion from side to side to cover the entire area of the fire.

5. Stand at a safe distance from the fire while using the fire extinguisher. Do not get too close to the flames as they can be extremely hot and dangerous.

6. If the fire does not go out after using the entire contents of the fire extinguisher, evacuate the area immediately and call the fire department for assistance.

7. After using the fire extinguisher, have it recharged or replaced as soon as possible to ensure it is ready for future use.

8. Remember to always follow the manufacturer's instructions and guidelines for using a fire extinguisher. It is important to receive proper training on how to use a fire extinguisher safely and effectively.
