The Correct Usage Method of Car Safety Hammer

Correct usage method of safety hammer: Take out the safety hammer from the car, then directly strike the four corners of the tempered glass. When slight cracking appears, it indicates that the internal stress distribution of the glass has been severely disrupted, leading to the instant formation of numerous spider-web cracks. At this point, just a few more strikes will shatter the glass. If the glass has a film, you need to exert force to kick it open, as the film has anti-shattering properties and won’t detach without sufficient external force. The car safety hammer, also known as a multifunctional safety hammer, is a tool installed in vehicles for breaking car windows to escape in emergencies or disasters. There are numerous brands of car safety hammers, with varying functions and styles. The hammer body can be made of plastic, wood, or steel, while the hammer head is always metal. Car safety hammers should only be used in emergencies, and safety precautions must be observed. When taking long-distance buses, it’s advisable to sit near the safety hammer, emergency door, or roof emergency exit. It’s also recommended to review the instructions for opening the emergency door beforehand. Private cars can also be equipped with safety hammers if necessary. If a private car is equipped with one, the hammer should be placed in an easily accessible location. In emergencies, the driver should aim for the center position, about two-thirds up from the bottom on either side, to ensure a quick escape.
I've been driving for over twenty years, and using a safety hammer requires proper timing and technique. Keep it in a visible spot in the car, like the glove compartment or door pocket—don’t bury it under clutter, or you won’t find it in an emergency. The method of use is crucial: first, unbuckle your seatbelt, stay calm, then grab the hammer and aim for the four corners of the window—not the center, because tempered glass is strongest in the middle and weakest at the corners. Strike hard with the hammer’s pointed end to ensure the glass shatters instantly. Prioritize breaking the window next to the driver’s seat or the rear window; avoid the windshield first, as it’s much harder to break. Once shattered, climb out quickly, being careful of glass shards. I recommend checking the hammer periodically for rust or wear and practicing with a water bottle in a safe environment to build muscle memory. Choose a lightweight hammer with sharp edges for quick effectiveness—road safety can’t be overlooked, especially in rain or at night.
When I first bought my car, I was particularly curious about the tools in it and spent a long time learning how to use the safety hammer. It usually has a spring-loaded design or a pointed tip, and it's best placed within easy reach, such as in the passenger door pocket. Using it is simple: first, make sure you're not trapped, then firmly grip the hammer's handle, aim for the edge or corner of the window, and strike hard—I once practiced with a water bottle in an open area, aiming precisely without hesitation. The key is not to hit the center of the glass, as it's too hard and likely to fail; the correct method is to strike the corner forcefully once, causing the glass to shatter into small pieces for a quick escape. I also enjoy sharing this experience with friends, discussing which brands of hammers work best, and recommending those with built-in rescue knives. Don’t overlook regular checks—in case of an emergency due to poor road conditions, this tool can save your life. Keep it clean and dry to ensure it remains functional.
