ANSI/ISEA Z89.1-2014

​Provide industrial hard hat performance and testing requirements​

This part of the standard specifies performance and testing requirements for industrial helmets, commonly known as hard hats. It establishes the types and classes of protective helmets, depending on the type of hazard encountered.

​2 Hard Hat Types​

A Type I hard hat cushions blows to the crown or top of the head. While no headgear can fully protect wearers from severe impacts or penetrations, ANSI Z89.1 hard hats deliver assurance that you’re protected from tools, small parts, or similar items falling from a reasonable height—or if you stand up under an obstruction and whack your head.​

A Type II hard hat reduces the impact from top-of-the-head blows and protects wearers from front, back, and side impacts. This is necessary when working around moving equipment or materials that create a persistent threat of horizontal blows.​​
