What are the common sense of safety helmets?
The user can not adjust the size of the hat liner at will, which will directly affect the protective performance of the helmet. Once the falling object impact occurs, the safety helmet will be directly damaged by the wearer because it is not worn firmly or out of contact with the top after impact.
The user can not disassemble or add attachments on the helmet so as not to affect the original protection performance.
Before use should check the safety cap, whether the appearance of crack, scratch, uneven wear, cap lining structure is complete, the cap liner is in normal state, obvious defects affecting the performance should be scrapped if there is a safety cap, so as not to affect the protective effect.
The wearer must wear the helmet when he is using it. He can not shake it. He should fasten the lower jaw and adjust the back hoop to prevent the helmet from falling off.
Do not secretly wear holes in the helmet, do not arbitrarily crash helmets, do not wear the helmet when the bench to sit, so as not to affect its strength.
