ANSI/ISEA Z89.1 is the American National Standard that sets out the performance and testing requirements for industrial safety helmets, often referred to as hard hats.
The standard defines types and classes of helmets based on the hazards present in the work environment, allowing employers and workers to select appropriate head protection for their specific needs.
Helmet Types under ANSI/ISEA Z89.1:
- Type I: Designed to reduce the force of impact resulting from a blow only to the top of the head.
- Type II: Designed to reduce the force of impact from both top and lateral (side) impacts.
Helmet Classes under ANSI/ISEA Z89.1:
These relate to the helmet’s electrical insulation properties:
- Class G (General): Tested at 2,200 volts.
- Class E (Electrical): Tested at 20,000 volts.
- Class C (Conductive): No electrical protection.
This classification system enables organisations to select a helmet based on impact type and electrical protection, tailored to the specific risks of the job site.

Key Points:
- ANSI/ISEA Z89.1 is the US standard for industrial safety helmets.
- It categorises helmets by Type I (top impact) and Type II (top and side impact).
- It defines electrical protection levels via Class G, Class E, and Class C.
- Helps ensure workers are protected according to specific site hazards.
