Hard hats are essential PPE for protecting workers from head injuries caused by falling objects and electrical hazards. OSHA mandates head protection when there's a risk of head injury from electrical burns or falling/flying objects. [1] [3]

Key considerations for hard hat use and maintenance include:

• Wearing the right hat for the job is crucial. Class E or B hats are approved for electrical work, with Class E being the newer standard. Type 1 hats protect against top impacts, while Type 2 protect against top and side impacts.
• Always wear the hard hat with the bill facing forward, as they are tested in this position. Avoid wearing other hats underneath to ensure proper fit and protection.
• Regularly inspect the hard hat for cracks, dents, frayed straps, and dulling, which can reduce protection. Clean with mild soap and water only.
• Avoid contact between the hard hat and electric wires.
• Never alter the hard hat shell or cushion-support suspension.
