Whitlock, Chuck . 2002. Your Hardhat: Inspection and Maintenance. 0267 2331. Missoula, MT: U.S. Department of Agriculture, Forest Service, National Technology and Development Program. 4 p.
Describes how to inspect and maintain a hardhat, one of the most important pieces of personal protective safety equipment. The hardhat has three parts: the shell, suspension system, and chinstrap. The shell, commonly made from a thermoplastic (such as polycarbonate), protects the wearer's head from penetration and impact injuries. The suspension system is designed to help absorb the impact of a blow to the wearer's head. The chinstrap is designed to keep the hardhat in place when it might otherwise shift or fall off. A simple hardhat field inspection involves compressing the shell from both sides about 1 inch with your hands and releasing the pressure without dropping the shell. The shell should return to its original shape quickly, exhibiting elasticity. If the shell being tested does not have as much elasticity as a new shell, or if the shell cracks, it should be replaced immediately.
