Head protection for industrial sites, rated for impact and electrical exposure.

**In short:** Head protection for industrial sites, rated for impact and electrical exposure. JJ Projects sources it to the specification the buyer names. Typical reference, standards: ANSI/ISEA Z89.1.

## Specification references

- Standards: ANSI/ISEA Z89.1
- Types: Type I (top impact) and Type II (top and lateral impact)
- Electrical classes: Class G, E or C

> Typical references only. The governing specification is the one on your purchase order or datasheet.

## Typical uses

- Head protection for workers on construction and fabrication sites
- Refineries, plants and shutdown or turnaround crews
- Visitor and inspector issue at industrial facilities
- Work near electrical equipment, using a class chosen for the exposure

## Questions

### What is the difference between Type I and Type II?

Under ANSI/ISEA Z89.1, Type I helmets are tested for impact to the top of the head. Type II helmets are also tested for impact from the sides, front and back. Your site safety plan decides which type is required.

### What do electrical classes G, E and C mean?

Class G is tested at a lower voltage, class E at a higher voltage, and class C offers no electrical protection. Class C helmets are often vented and should not be worn near energized conductors. Choose the class for the hazard on site.

### Do hard hats expire?

Manufacturers state a service life for the shell and the suspension, and a helmet that has taken a heavy blow or shows cracks or damage must be replaced. Follow the manufacturer's instructions and your site safety rules.
