Hard Hats

Class G

  • (General) Hard Hats are designed to reduce exposure to low voltage conductors, and offer dielectric protection up to 2,200 volts (phase to ground). As is the case with Class E hard hats, this amount of voltage protection is designated to the head only, and does not account for voltage protection allocated to the user as a whole.

Class E

  • (Electrical) Hard Hats are designed to reduce exposure to high voltage conductors, and offer dielectric protection up to 20,000 volts (phase to ground). This amount of voltage protection, however, is designated to the head only, and is not an indication of voltage protection allocated to the user as a whole.

Class C

  • (Conductive) Hard Hats differ from their counterparts in that they are not intended to provide protection against contact with electrical conductors.
