Full Brim Hard Hats

In plain words. Hard hats are marked under ANSI/ISEA Z89.1. Type I protects against a blow to the top of the head; Type II also protects against blows from the side, front and back. The electrical class is separate: Class G (general) is tested to 2,200 volts, Class E (electrical) to 20,000 volts, Class C (conductive) is not tested for electrical protection and may be vented. Bump caps are not hard hats; they protect against bumps and scrapes only. The manufacturer prints the Type and Class inside the shell.

Technical. ANSI/ISEA Z89.1-2014 (R2019): Type I impact and penetration from above; Type II adds lateral impact (EN 12492 climbing-style helmets are tested similarly and are sold here where the manufacturer rates them to Z89.1 Type II); Class G 2,200 V, Class E 20,000 V, Class C no electrical rating; optional marks LT (low temperature, −30 °C), HV (high visibility), and the reverse-donning arrow. CSA Z94.1 is the Canadian equivalent. Suspension points, ratchet or pin-lock adjustment, brim style and vents are as published.
