Which class of helmet is used to reduce the danger of contact with low voltage conductors?

The correct choice is Class G helmets. These helmets are specifically designed to provide protection against low voltage electrical conductors. Class G, or General helmets, are tested for electrical protection up to 2,200 volts and are intended for use in environments where low voltage electrical hazards may be present. The use of Class G helmets is essential in ensuring the safety of workers who might come into contact with live electrical components, thereby minimizing the risk of electric shock.

In contrast, Class E helmets offer protection against high voltage electrical conductors, with a testing voltage of up to 20,000 volts, making them suitable for high voltage work environments but not specifically designed for low voltage situations. Class C helmets do not provide any electrical protection; they are primarily designed for impact protection and are not insulated against electrical hazards. Class D helmets are similarly geared toward non-electrical risks and do not offer electrical insulation. Therefore, when dealing with environments with low voltage conductors, Class G helmets are the appropriate choice to ensure safety and compliance with electrical safety standards.
