Hard Hat Classes Explained: Type I vs Type II, Class E, G & C
Not all hard hats are created equal. Understanding the classification system is critical to ensuring workers have the right protection for their specific hazards. This article breaks down the ANSI/ISEA Z89.1 hard hat types and classes in plain language.
Type I vs. Type II
Type I helmets protect only the top of the head. They are the most common and are suitable for most general construction environments where hazards come from above.
Type II helmets provide protection to the top AND sides of the head. They are recommended for environments where lateral impacts are a risk, such as confined spaces or areas with low overhead clearance.
Electrical Classes
- Class E (Electrical): Tested to 20,000 volts. Required for electrical workers and utility linemen.
- Class G (General): Tested to 2,200 volts. Suitable for general construction and industrial use.
- Class C (Conductive): Offers NO electrical protection. Used in environments where electrical hazards are absent but ventilation or comfort is prioritized.
How to Read the Label Inside Your Hard Hat
Every ANSI-compliant hard hat has a label inside the shell that lists the manufacturer, date of manufacture, ANSI standard version, Type, and Class. Always check this label before use.
When to Replace Your Hard Hat
Hard hats should be replaced after any significant impact, even if no visible damage is present. Additionally, replace the shell every 2–5 years and the suspension every 12 months, or per manufacturer guidelines.
