Class G (General) hard hats are rated to provide protection from up to 2,200 volts of electricity. They are “general” because that level of protection is sufficient for most jobs. Class E (Electrical) hard hats provide a much higher level of protection, and are rated for up to 20,000 volts.
What is the difference between Type I and Type II hard hats?
Type I: Have a full brim around the entire hat. These are only mean to to protect workers from object blows that come from above and strike the top of the helmet. Type II Have a short brim only in front. These hard hats are designed to offer protection from lateral blows and objects.
