Avoid placing a hard hat where it may be exposed to direct sunlight. Hard hats should be inspected for dents, cracks, brittleness, tears, or other damage before use. Both the shell and suspension should be inspected. Any hat subjected to a heavy blow should be replaced. Bump caps are not acceptable in areas where hard hats are required.
Bump caps are lightweight and durable but only provide protection from minor bumps and abrasions.
Hard hats are effective only if worn properly. Hard hats should be worn straight and not angled. Never wear a hard hat backwards. Hard hats should be as light as possible and carefully adjusted to fit the wearer. Hard hats shall be worn with the suspension in place.
