Final answer:
Class C hard hats are conductive and don't provide electrical protection. For electrical hazards, workers should use Class E or G hard hats. Choosing the right class of hard hats is essential for safety.
Step-by-step explanation:
The class of hard hats that are conductive and do not provide any electrical protection for your head are Class C hard hats.
These hard hats are designed primarily to prevent impact injuries but are not intended for environments where electrical hazards are present.
For protection against electrical hazards, one would need to consider Class E (electrical) hard hats, which are tested to protect the wearer from high voltage shocks, or Class G (general) hard hats that provide some electrical protection up to a certain voltage.
Workers must choose the appropriate class of hard hats to ensure safety in their specific work environment.
