Yes. Hard hats are divided into three industrial classes:
Class G hard hats provide good impact protection but limited voltage protection. They are best for use in mining, building construction, shipbuilding, lumbering, and manufacturing.
Class E helmets provide excellent protection for electrical workers in that they protect against falling objects and high-voltage shock and burns.
Class C light-weight helmets offer limited protection. They protect workers from bumping against fixed objects but do not protect against falling objects or electric shock.
Most hard hat hard hats today offer all 3 categories and called a type 1 hard hat class C,E, & G.
