Which class of helmets provides low voltage protection according to ANSI Z89.1-1997 specifications?

1. Class E

2. Class G

3. Class C

4. Class A

The correct answer is: Class G

The class of helmets that provides low voltage protection according to ANSI Z89.1-1997 specifications is Class G. This classification specifically indicates that the helmet is intended to provide protection from electrical hazards at voltages no greater than 2,200 volts. In the context of safety helmets, Class G helmets are designed for general use and offer protection against impact and penetration as well as electrical hazards. This makes them suitable for workers who may be exposed to low voltage electrical risks in their environments. It's important to differentiate this from the other helmet classifications. Class E helmets are designed for electrical environments with a higher voltage protection level (up to 20,000 volts). Class C helmets do not provide any electrical protection; they are primarily for impact protection with no insulating properties. Class A helmets offer a combination of impact and limited electrical protection, but not specifically focused on low voltage like Class G. The classifications established by ANSI Z89.1 help ensure that workers select the appropriate head protection for the specific hazards they may encounter, making safety compliance and risk management more effective.
