CSA Z96 vs ANSI/ISEA 107: Canadian and U.S. Hi-Vis Standards
Which high-visibility clothing standard applies in Canada versus the United States? Canadian buyers commonly check CSA Z96:22; U.S. purchasers commonly refer to ANSI/ISEA 107-2020. Both address worker visibility, but they are not interchangeable certifications. OSHA is a U.S. workplace safety regulator, not the publisher of ANSI/ISEA 107.
Canada: CSA Z96:22 high-visibility apparel
CSA Z96:22 is a Canadian standard for high-visibility safety apparel. It addresses the visual performance, placement and minimum areas of conspicuous materials, including background fabric and retroreflective components. Its Class 1, 2 and 3 designations describe increasing garment coverage and conspicuity. A garment's class alone is not a universal instruction for every job; employers must assess the worksite and the legislation that applies.
When purchasing for Canadian workplaces, check the manufacturer's garment label or technical datasheet for the claimed CSA edition, class and any applicable performance information. Avoid assuming that every bright-coloured shirt or vest complies with CSA Z96.
United States: ANSI/ISEA 107 high-visibility apparel
ANSI/ISEA 107-2020 is the U.S. consensus standard for high-visibility safety apparel. It identifies garments by both Type (the expected-use setting) and Performance Class (the amounts and configuration of visible materials). Selection therefore involves more than comparing a Canadian class number with a U.S. class number. Check the garment marking and any applicable U.S. jobsite or agency requirements.
What is OSHA's role?
OSHA regulates workplace safety in the United States. ANSI/ISEA develops the apparel consensus standard; it is misleading to call ANSI/ISEA 107 an “OSHA standard.” Whether and when high-visibility clothing is required depends on the relevant federal, state, transport and site requirements. For example, OSHA discusses highway and road-construction exposure to vehicular traffic in its published interpretation guidance.
CSA Z96 versus ANSI/ISEA 107: practical differences
- Jurisdiction: CSA Z96:22 is the Canadian apparel specification; ANSI/ISEA 107-2020 is the U.S. apparel specification.
- Markings: Read the complete garment label. The classification systems and their underlying criteria are not identical.
- Worksite rules: National apparel standards and legally applicable worker-protection obligations are distinct. A province, state, employer or project may require particular garments.
- Purchase decision: Confirm the garments' declared compliance and assess the worksite's visibility hazards before ordering.
What about Ontario construction projects?
Ontario has a specific rule for workers who may be endangered by vehicular traffic: O. Reg. 213/91, section 69.1. That is a separate legal question from comparing Canada's and the United States' apparel standards. Read our Ontario Regulation 213/91 versus CSA Z96 guide for the provincial requirements.
