Edward W. Bullard invented the hard hat in 1919, then patented it in 1929. It's credited with saving lives on job sites while also becoming a symbol of working-class America.

Class G and Class E hard hats must meet appropriate performance requirements. Class G must withstand 2,200 volts for one minute, and maximum leakage shall not exceed three milliamperes.

Hard hats are available with varying levels of protection: Type I is the most common type of head protection. Type I protects the top of the head from impact. Type II protects the top and sides of the ...

Hard hats also come in classes with different levels of electrical protection: Class G is a “general” hard hat with electrical rating of 2,200 V, class E “electrical” hard hats have a rating of 20,000 ...
