Helmet with full brim, not less than 1.25 inches wide.
Brimless helmet with a peak extending forward from the crown.
Intended for protection against impact hazards and provide limited voltage protection.
Provide impact and penetration protection from falling or flying objects and from high-voltage shock and burn. Used extensively by electrical workers.
Designed specifically for light-weight comfort and impact protection. Offers no dielectric protection, often referred to as a “bump cap.”
Helmets intended to reduce the force of impact resulting from a blow only to the top of the head.
Helmets intended to reduce the force of impact resulting from a blow which may be received off center or to the top of the head.
Class G helmets are intended to reduce the danger of contact exposure to low voltage conductors. Test samples are prooftested at 2,200 volts (phase to ground). However, this voltage is not intended as an indication of the voltage at which the helmet protects the wearer.
Class E helmets are intended to reduce the danger of exposure to high voltage conductors. Test samples are proof-tested at 20,000 volts (phase to ground). However, this voltage is not intended as an indication of the voltage at which the helmet protects the wearer.
Class C helmets are not intended to provide protection against contact with electrical conductors.
- Adjust the headband to the proper size so there is adequate clearance between the shell and the headband and space to allow ventilation.
- If a sweatband is used, it must cover at least the forehead portion of the headband.
- Adjust the straps so they remain in place and the helmet stays firmly on the head.
- The strap should, however, break at a reasonably low force to prevent a strangulation hazard.
