Selection Guidelines for Head Protection

When selecting head protection, knowledge of potential for falling objects and electrical hazards is important. When it’s determined that these hazards exist, choose the most appropriate helmet from the categories listed below.

Impact Type Helmets

  • Type I: A helmet of Type I is designed to provide protection only to the top of the head. It is not intended to provide impact from side impacts. (This is by far the most commonly used type of hard hat in use.)
  • Type II: A helmet of Type II is designed to provide protection against both top and side impacts.

Electrical Classes

Class G (General): Class G helmets are intended to reduce the danger of contact exposure to low voltage conductors. Test samples are proof-tested at 2200 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 (Electrical): 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 (Conductive): Class C helmets are not intended to provide protection against contact with electrical conductors.

Bump Caps Bump caps/skull guards should be issued and worn for protection against scalp lacerations from contact with sharp objects. However, it’s very important to understand that they must not be worn as substitutes for safety caps/hats because they do not provide protection from impact forces or penetration by falling objects.
