The pressure gauge needle of a fire extinguisher indicates normal when it is in the green zone. Vehicle fire extinguishers are mostly dry powder extinguishers. The storage environment temperature for fire extinguishers should be within the range of -10 to 45 degrees Celsius, and the placement location should be kept dry and ventilated to prevent moisture corrosion. Fire extinguishers are categorized into: 1. Aerosol fire extinguishers; 2. Dry powder fire extinguishers; 3. Ultra-fine dry powder fire extinguishers; 4. Carbon dioxide fire extinguishers; 5. Water-based fire extinguishers. The method of using a fire extinguisher is: 1. Carry the fire extinguisher to a spot near the fire and stand on the upwind side; 2. Pull out the safety pin; 3. Hold the nozzle tube firmly with one hand; 4. Press the handle with the other hand; 5. Aim the nozzle at the base of the flame and sweep.
