Hard Hat Types and Classes Standards

All hard hats are classified according to the specific impact and electrical performance requirements they are designed to meet. This classification is also commonly refered to as the ANSI Z89.1 standard. All hard hats in accordance with this standard meet or exceed either Type I or Type II impact requirements. In addition to type classifications, all hard hats are further classified as meeting Class G, Class E, or Class C electrical requirements. Below we outline each of these types and electrical classes.

All hard hats are shipped with an ANSI certification label on the inside of the hard hat’s shell. This label will clearly identify what type and class standards it was designed to meet. If this label is missing or cannot be read it is recommended that it should be replaced.

Hard Hat Impact Types

Type I Hard Hats

Type I hard hats are intended to reduce the force of impact resulting for a blow only to the top of the head.

Type II Hard Hats

Type II hard hats are intended to reduce the force of impact resulting from a blow which may be received off center or to the top of the head. A Type II hard hat typically is lined on the inside with thick high density foam.

Electrical Classes

Class G (General)

Class G hard hats 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 hard hat protects the wearer. Please note: Class G hard hats were formerly known as Class A.

Class E (Electrical)

Class E hard hats 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. Please note: Class E hard hats were formerly known as Class B.

Class C (Conductive)

Class C hard hats are not intended to provide protection against contact with electrical conductors.
