Head Protection

This category includes items worn to prevent the head as a whole from being injured due to impacts, penetrations, contact with electrical hazards, etc., rather than garments worn specifically to protect the eyes or breathing. Protective headgear typically refers to hard hats, which incorporate a hard outer shell and a shock-absorbing lining that are resistant to penetration, absorb and dissipate the shock of a blow, are water resistant, made of slow-burning or inflammable material, and incorporates a headband and straps to suspend the shell away from direct contact with the head. Hard hats are divided into Class A (impact and penetration resistance, along with voltage protection up to 2,200 volts), Class B (impact and penetration resistance, high-voltage shock and burn protection up to 20,000 volts), and Class C (lightweight and comfortable, impact resistant, but no protection from electrical hazards).
