What is the difference between Type I and Type II hard hats?
According to the American National Standards Institute (ANSI) Z89.1- 2003 American National Standard for Industrial Head Protection, Type I hard hats provide impact protection from blows received to the top of the head only. Type II hard hats provide impact protection from blows to the top and sides of the head. What are the different classes of hard hats and what do they specify? Under ANSI Z89.1-2003, three classes of hard hats are recognized: • Class G (general) hard hats meet impact, penetration and dielectric requirements. The shell is tested at 2,200 volts for one minute. • Class E (electrical) hard hats also meet impact, penetration and dielectric requirements. The shell is tested at 20,000 volts for three minutes. • Class C (conductive) hard hats provide impact and penetration protection only. They do not have any electrical insulation. What is the difference between a bump cap and hard hat? When would I use one versus the other? Bump caps do not provide any impact protection f
