Head equipment protects against impact blows to the head. Helmets come in different classes and don't offer the same level of protection. So, finding a helmet type suited to the work environment is highly important. The American National Standards Institute (ANSI) categorizes helmets into different types and categories:
- Type 1: These are helmets with a full brim more than 1¼ inches wide around the entire hat
- Type 2: These helmets come with a short brim that extends forward from the crown
There are three electrical performance classes:
- Class A: protects the head against low-voltage electrical conductors, impact, and penetration. Helmets get proof-tested at 2,200V of electric charge for certification purposes.
- Class B: These are utility service helmets, and they protect against penetration, impact, and high-voltage electrical conductors. Proof-testing for class B occurs at 20,000V.
- Class C: Class C helmets are typically made from aluminum and only offer penetration and impact protection. Thus, they should not be used in areas with electrical hazards.
The voltages indicated in Classes A and B don't state the voltage the helmets protect wearers. Helmets also get tested for penetration and impact resistance from flames, water absorption, and blows to the top of wearers' heads.
