Convert safety-equipment ratings between the US (ANSI/ISEA, NIOSH), Canadian (CSA), and European (EN / EN ISO) systems. Pick a category — cut gloves, respirators, hard hats, hi-vis, eye, or hearing. Every mapping is a functional equivalence for selection, not a legal substitution: buy to the standard your jurisdiction enforces.
How to use these conversions
Spec the test, not the badge. A purchase line that reads "EN 388 TDM level D or ANSI/ISEA 105 A4" names the same protection twice and lets buyers source from either market — and dual-certified products remove the guesswork entirely. The deep-dive references behind each mapping: CSA Z94.1 vs ANSI Z89.1 hard hats, N95 vs FFP2 vs FFP3 respirators, and EN 388 vs ANSI/ISEA 105 cut levels.
The one rule that overrides every conversion: functional equivalence is not legal equivalence. US OSHA-covered workplaces need US-certified equipment (ANSI/ISEA, NIOSH); Canadian sites expect CSA marks; EU/UK sites need CE and EN certification. These tables help you shop across markets and read foreign listings — they don't let you substitute one certification for another in a compliance program.
