Industry Standards

Sure it's made of the usual still shell.  Now does this guarantee that your hard hat gives you the protection that you need?  If anything, you should make sure that the hard hat you own meets industry standards.  

This is especially true if what you have was provided for by your company and that you are working for an enterprise known for doing just about anything to keep expenses low.  You would not want to become another victim of unscrupulous company cost-cutting practices.

Purchase Your Own Hard Hat
