The document discusses safety procedures for wearing hard hats. It notes that head injuries are often fatal or cause serious damage, so hard hats are important for prevention. Proper wearing of hard hats helps prevent heads contacting objects and objects contacting heads. When wearing a hard hat, the headband should be adjusted to fit, the shell and harness checked for damage, and a chin strap may be needed for working at heights. Holes should not be added and damaged hats replaced. Writing on hard hats is discouraged as markers and stickers can damage the protective coating.
