Which type of ANSI hard hat is tested at 2200 V?

The Class A ANSI hard hat is designed to provide the highest level of protection against electrical hazards, rated for use in environments where there is a potential for exposure to low voltage electrical conductors. It is tested to withstand an electrical shock of up to 2200 volts, making it suitable for tasks in electrical construction and maintenance where such risks are present.

In contrast, while Class B and Class C hard hats provide varying degrees of electrical protection, they do not meet the same voltage ratings as Class A. Class B provides protection against higher voltages (up to 20,000 volts) but is not rated for the same low voltage applications as Class A, whereas Class C does not offer any electrical insulation properties and is primarily meant for impact protection. Each class serves distinct purposes, but for workers needing protection from low voltage environments while also ensuring impact resistance, Class A is the appropriate choice.
