Hard hat
From Wikipedia, the free encyclopedia
- For "hardhat diving", see Standard diving dress.
A hard hat is a type of helmet predominantly used in workplace environments such as construction sites designed to protect the head from injury such as from falling objects, debris and bad weather. They are typically required personal protective equipment where heavy labor is being performed. They used to be made out of metal, but since the 1960s, rigid plastic is the preferred material.
Its lower edge sometimes has a small gutter to catch rainwater and shed it off the front peak and not down inside the wearer's coat neck.
They can sometimes be fitted with these accessories:-
- A visor like in a riotsquad helmet but thinner.
- A welding visor.
- Ear protectors.
- A Helmet Light Mount, to provide more light in low-light conditions while letting the wearer work with both his hands free.
Blue-collar workers who engage in heavy professions that require protective equipment are often called hard hats.
