How do you flag OSHA + NFPA 70E + ANSI 107 compliance per SKU?

Three real regulations, three EAV attribute groups, all queryable.

• OSHA (general PPE under 29 CFR 1910). I model this as a multi-select attribute on the product: head protection / eye protection / hand protection / foot protection / hearing protection / fall protection. Used for site-search filters and PDP badges. Safety managers buying for an OSHA-audited site can filter the whole catalog.
• NFPA 70E (electric-arc flame-resistant clothing). Two attributes: ATPV/EBT rating in cal/cm² (numeric, 4 / 8 / 12 / 25 / 40+ are the standard tiers) and HRC category (1 / 2 / 3 / 4 mapping to incident-energy ranges). Layered facet on category pages: "Bulwark FR shirts ≥ 8 cal/cm²" returns the right subset. UL-certified brands like Bulwark, Carhartt FR, Wrangler FR, RIGGS publish the ratings on every spec sheet, I auto-import from their feeds.
• ANSI 107 (HiVis high-visibility). Two attributes: class (1 = parking-lot, 2 = roadway, 3 = highway / rail / night) and background color (fluorescent yellow-green / orange-red). Filter by class for compliance-buying for road-construction crews. Carhartt HiVis, Pyramex, ML Kishigo all publish ANSI 107 ratings; the rating is the SKU-level attribute, not a category.

Plus USDA / NSF for food-service uniforms (laundering protocol attribute) and HACCP for processing-plant uniforms (apron / boot / hairnet bundles). All five are queryable filters on category + search, and render as compliance badges on PDP via a simple foreach on the multi-select attribute values. No magic, just Magento EAV used correctly.
