Understanding Hard Hat Standards

OSHA requires employers to provide head protection when workers are exposed to falling objects, electrical shock, or other hazards. Here's what you need to know.

1 Hard Hat Types (ANSI Z89.1)

Type I

Designed to reduce the force of impact resulting from a blow to the top of the head.

Best for: General construction, roofing, carpentry

Type II

Designed to reduce the force of impact from both top AND side impacts.

Best for: Utilities, traffic work, forestry

2 Electrical Classes

Class G

20kV

General use. Protects against 2,200 volts AC.

Class E

20kV

Electrical. Highest protection available.

Class C

0

Conductive. NOT for electrical work.

OSHA Requirements

  • Hard hats must be worn when there's risk of head injury from falling objects, electrical shock, or impact hazards
  • Hard hats must meet ANSI Z89.1 standards (OSHA requirement under 29 CFR 1910.135)
  • Inspect hard hats regularly for cracks, dents, or signs of wear
  • Replace hard hats every 2-5 years, or immediately after any significant impact

Check the Manufacture Date Inside Your Hard Hat

Every ANSI-certified hard hat has the manufacture date printed inside the shell. This is required by ANSI Z89.1 standards and is your key to knowing when to replace your hard hat.

How to Find the Date:

  1. 1 Remove the suspension system (the straps inside)
  2. 2 Look on the underside of the dome for stamped text
  3. 3 You'll see something like: "MFG DATE: 08/23" or "EXP: 08/28"

Typical Lifespan

  • • Polycarbonate shells: 5 years
  • • Fiberglass shells: 5 years
  • • HDPE shells: 3-5 years
  • • ABS shells: 3-5 years

Replace Immediately If:

  • • Any visible cracks or dents
  • • Faded or chalky shell surface
  • • Hard hat has been struck by heavy impact
  • • Suspension system is damaged
