Hard hats are helmets that are worn in workplace environments such as industrial or construction sites to protect the head from injury due to falling objects, impact with other objects, debris, rain, and electric shock1. Hard hats have suspension bands inside the helmet that spread the helmet’s weight and the force of any impact over the top of the head1. Hard hats are regulated by ANSI standards
There are two types of hard hats according to ANSI standards: Type I and Type II. Type I hard hats provide protection to the top of the head only, while Type II hard hats provide protection to both the top and sides of the head. Type I hard hats are commonly used in the United States, while Type II hard hats are commonly used in Europe.
