Which class of hardhat provides no electrical protection?

Class C hard hats are designed primarily to provide impact protection and do not offer electrical protection. They may be manufactured from conductive materials which can actually pose a risk in environments where electrical hazards are present. This is essential for workers to understand, as the lack of electrical insulation means that Class C hard hats are suitable only for construction contexts where electricity is not a concern.

In contrast, Class G hard hats are designed for low-voltage electrical environments and offer some level of protection against electrical hazards. Class E hard hats provide a higher level of electrical protection and can withstand high-voltage situations. Class A hard hats combine the features of both G and E classes, offering protection from electrical hazards as well as impact. Thus, the choice of hard hat class is critical to ensure safety in environments specific to the hazards present.
