How to Use a Fire Extinguisher to Put Out Fire in Subject 4?

When extinguishing a fire, you can quickly rush to the fire scene by carrying the fire extinguisher in hand or on your shoulder, and place it down about 5 meters away from the burning area. Outdoors, you should choose to spray in the upwind direction. If the dry powder fire extinguisher is an external type, the operator should hold the spray gun tightly with one hand and lift the opening ring on the gas storage cylinder with the other hand. Turn it counterclockwise to the highest position, then lift the fire extinguisher. Once the dry powder is ejected, quickly aim at the base of the flame and sweep. If it is a built-in gas storage cylinder, first pull out the safety pin, hold the front nozzle part of the spray hose, then press down the opening lever to activate the fire extinguisher for firefighting. For fire extinguishers with spray hoses or stored-pressure fire extinguishers, one hand should always press down the lever during use and not release it, otherwise the spray will be interrupted.
I remember the fire extinguisher usage in the Subject 4 test very clearly. During driving lessons that day, the instructor explained the PASS method in detail: Pull (remove the safety pin), Aim (point at the base of the fire), Squeeze (press the handle), and Sweep (sweep side to side to cover the fire area). Vehicle fire extinguishers are usually dry powder type, especially useful for small vehicle fires, such as engine smoke or short circuits in wiring. After practice, I often thought that this test isn't just for passing, but to react quickly in case of a real accident. The first step to safety is maintaining a distance of 2-3 meters and not spraying in panic. The pressure gauge of the fire extinguisher needs regular checks to avoid failure. After learning, I understood why a driver's responsibility isn't just about driving, but also includes handling emergencies.
The correct usage of fire extinguishers is a practical key point in Subject 4. Just remember the PASS acronym: Pull the pin, Aim at the base of the fire, Squeeze the handle, and Sweep from side to side. When actually driving, keep an effective fire extinguisher in an easily accessible location. Don't panic when encountering a small fire - just aim at the base and spray for 10-15 seconds. I've seen others mistakenly spray into the air while extinguishing a fire, which actually made the flames worse. This is emphasized in the exam because timely handling of sudden fires on the road can prevent them from spreading to the entire vehicle. Regular practice simulations will help you become more familiar with the action rhythm. Make it a habit to check the fire extinguisher's expiration date every six months - this is crucial for safe driving.
