Where to Hit the Window with a Safety Hammer?
2 Answers
Safety hammers should be used to strike the corners of the car window glass. The specific method is as follows: after picking up the safety hammer, strike around the edges of the window, because the tempered glass on the window is strongest in the middle and weakest at the corners and edges. If passengers hit the middle of the window, the broken area will be smaller, making it harder and slower to escape. Important notes: 1. If a safety hammer is not available: try using a sharp, sturdy object to strike the tempered glass—the sharper and thinner the better. However, experiments have shown that using keys or high-heel shoe tips (except for metal heels) to strike tempered glass is unreliable. 2. After exiting the vehicle, do not turn back to watch: it is best to stay at least 20 meters away from the vehicle to avoid potential explosions or other dangers. 3. The safety blade at the end: in emergencies, it can also be used to cut seat belts, helping drivers and passengers escape.
To break car glass with a safety hammer, the key is to find the right spot. Based on my 20+ years of driving experience, don’t waste effort hitting the center—it’s ineffective. The four corners of the window are the weakest points, like the top-left, top-right, bottom-left, and bottom-right corners, especially those near the door frame. Tempered glass is designed to bear the most pressure at the corners, so a hard strike there will shatter the entire pane into small fragments, reducing the risk of cuts. In emergencies like a submerged car, act fast: first unbuckle your seatbelt, grab the safety hammer, strike a corner forcefully, then escape. Always keep a high-quality safety hammer near the driver’s seat and practice periodically—don’t wait for an emergency to figure it out. During car maintenance, also check if the glass is aging; some accident-damaged glass may have cracks that need prompt repair for safety.
