sperian personal protective equipment: A safety helmet is a hat that protects the human head from injuries caused by falling objects and other specific factors. The safety helmet consists of a shell, liner, chin strap, and accessories. Cushioning and shock absorption: There is a gap of 25~50mm between the shell and the liner. When an object strikes the safety helmet, the shell does not deform under force to directly affect the top of the head. Stress dispersion: The shell is oval or hemispherical with a smooth surface. When an object falls onto the shell, it cannot stay and slides off immediately; moreover, the force borne by the impact point on the shell is transmitted to the surrounding area.
