OSHA 30 Jobs in California

OSHA 30-hour certification is the supervisory-level construction safety credential — a 30-hour course that covers everything in OSHA 10 plus deeper content on site management, recordkeeping, and subcontractor coordination. In California, employers requiring OSHA 30 are generally hiring lead technicians, foremen, or project managers who will oversee crews and be accountable for jobsite safety compliance. It's increasingly expected by general contractors before approving a mechanical sub's crew on commercial projects.

OSHA 30 completion cards are accepted nationwide and have no federal expiration date, though individual employers and project owners may set their own renewal windows. In California, commercial general contractors operating on federally funded or prevailing-wage projects frequently mandate OSHA 30 for any foreman or lead on their project. Technicians who have already completed OSHA 10 receive full credit for that content — the 30-hour course builds on the 10-hour foundation rather than repeating it.
