Under what circumstances should helmets be used?
Safety helmet is a kind of protective equipment to prevent impact from damaging the head. It consists of a hat shell, a cap lining, a lower cheek belt and a back hoop. The cap shell is hemispherical, firm and smooth, and has a certain elasticity, the impact of the impact and the puncture kinetic energy are mainly borne by the cap shell.
Enter the construction site, always wear safety helmet.
There is a certain space between the cap and the cap to buffer and disperse the instantaneous impact force so as to avoid or reduce the direct injury to the head. Impact absorption property, puncture resistance, lateral rigidity, electrical insulation and flame retardancy are the basic technical requirements of safety helmet.
