Periodic cleaning and inspection will extend the useful life of head protection. A daily inspection of the hard hat shell, suspension system, and other accessories for holes, cracks, tears or other damage that might compromise the protective value of the hat is essential.
Paints, paint thinners, and some cleaning agents can weaken the shells of hard hats and may eliminate electrical resistance. Employers should consult the helmet manufacturer for information on the effects of paint and cleaning materials on their hard hats.
Do not store head protection in direct sunlight, such as on the rear window shelf of a car, since sunlight and extreme heat can damage them.
