How to use the 4-in-1 safety hammer to gradually increase the force of the blows

In an emergency, passengers may need to use the 4-in-1 safety hammer to break the window to escape. At this time, it is crucial to master the appropriate force of the blows. Because the material, thickness and installation method of the window glass of different vehicles may vary, it is often difficult to accurately predict the effect of the blow applied at one time. In order to maximize the window breaking effect and reduce potential risks, it is recommended to take a step-by-step approach to increasing the force of the blows.
Preliminary attempt: Make an initial blow to the window with a moderate and controlled force. This force should be enough to make sufficient contact between the hammer head and the glass, but not enough to cause the glass to break immediately. The purpose of this step is to test the reactivity of the glass and determine the approximate breaking point.
Observe the feedback: After the initial blow, carefully observe the changes on the surface of the glass. If the glass cracks or dents, it means that the blow has taken effect on the glass, but further efforts may be needed. If the glass has almost no reaction, it may be necessary to increase the force of the blows slightly.
Gradually increase: According to the feedback from the initial blow, gradually increase the force of the blows. Each increase in force should be moderate to avoid a sudden increase in force that causes glass fragments to fly. By gradually increasing the force, the window breaking process can be controlled more accurately to ensure safety.
Continuous observation: During the entire knocking process, continue to observe the changes in the glass. Once you find signs that the glass is about to break, you should appropriately reduce the force of the knock or stop knocking to avoid excessive damage and causing fragments to fly.
