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.

The fire extinguisher knowledge in Subject 4 is really important. When using it, follow the PASS technique: Pull the pin, Aim at the base of the flame, Squeeze the handle, and Sweep from side to side. Most vehicle fire extinguishers are ABC type, effective against oil fires and electrical fires. In an emergency, don't get too close, and staying calm is key. I noticed this is covered in the exam to enhance drivers' emergency response capabilities and reduce accident risks. Keeping a fire extinguisher near the toolbox can prevent small incidents from escalating.

The usage of a fire extinguisher is quite simple: Pull out the safety pin, aim directly at the base of the flames, press the handle, and sweep side to side until the fire is out. Learning this in Subject 4 is to prepare for unexpected situations while driving, such as battery short circuits or oil fires. Remember not to spray towards the smoke, as this can make the fire more likely to reignite. In practice, if you have a fire extinguisher in your car, don't store it deep in the trunk—keep it near the driver's seat for quick access. Regularly check it to avoid expiration or failure. During the exam, practice the operation a few times, and you'll feel more comfortable with it. This small skill might save your life in a critical moment.

The fire extinguisher test point in Subject 4 is very practical. Follow the PASS method: Pull the pin first, Aim at the base of the flame, Squeeze the handle to discharge powder, and Sweep side to side to cover the area. Vehicle-mounted dry powder extinguishers are suitable for ordinary fires; stand firm and avoid tilting when using. The exam emphasizes this because staying calm during a fire can minimize losses. I suggest practicing simulated actions once or twice weekly to improve exam pass rates. Also, maintain the extinguisher regularly to ensure the pressure gauge is in the green zone. Remember the safety rule: extinguish small fires yourself, but evacuate and call for help with large fires.
