【Integrated】Hard hats can really defend you?

A safety helmet is a shallow dome hat made of steel or similar raw materials that is worn to protect the top of the head, and a protective article that prevents impacts from damaging the head. Consists of a cap shell, a cap liner, a lower cheek strap, and a rear hoop. Can a safety helmet really guard you? Drop a brick from high altitude and see what happens!

Ordinary bricks drop

Basically nothing serious

What about a 20 kg big iron ball?

The sloppy smashing means that ordinary bricks are dropped. The safety helmet is very safe. If there are many common smashing stones on the construction site, you must bring a safety helmet. If it is heavy, you must quickly avoid it. The following is the comments of netizens

@ Past wind: You must wear, and you are better than you are not

@He Yingying: I have seen that people in the company wear helmets that are thicker than those of migrant workers.

@ Hit the arms: I personally experienced, in the demolition of the excavator hook ground beam rebounded to my head, if it was estimated that wearing a ditch on the head is light

@ Sky Blue: There must be a plastic net in the helmet to have foam, which is only acceptable
