Hard Hats- Old ANSI Standards

If you are a hard hat wearer, you should know a few things about the new ANSI Z89.1-1997 Standard for Industrial Protective Helmets:
The standard kind of hard hat you've worn for years is now called a Type I helmet, a helmet that provides protection for the top of your head.
Helmets that provide some degree of top and off-center protection are addressed in the new ANSI Z89.1-1997 Standard and are called Type II helmets.
Helmet wearers must decide whether or not the Type I (top impact) helmet you currently use meets your requirements, or if your work conditions warrant a Type II (top and lateral impact) helmet.
The Standard provides minimum performance requirements to reduce the forces of impact and penetration from falling objects, and where applicable, to provide protection from electrical shock hazards
