In addition to ANSI impact standards, hard hats are also graded for electrical performance. ANSI Class C (Conductive) hard hats provide no protection against electric shock. ANSI Class G (General) hard hats protect the head from up to 2,200 volts and are the most common class of hard hat. For workers in high-voltage environments, ANSI Class E (Electrical) hard hats are certified to protect against up to 20,000 volts of current. You’ll find Class C, Class G, and Class E hard hats available from CustomHardHats.com.
