There is a big difference between a safety helmet and a safety helmet, mainly due to the different protection ranges. A safety helmet mainly protects the top of the head and is generally designed to prevent damage caused by high-altitude falling objects. Helmets have protective functions on the top, front, and sides of the head. In contrast, the impact surface and cushioning force that a helmet can withstand are much smaller than those of a helmet. Therefore, wearing a safety helmet cannot replace the protective effect of a safety helmet.
