What is OSHA 30?
The OSHA 30-Hour Construction Outreach Training is the supervisor-level version of OSHA 10. It expands on the Focus Four hazards with deeper coverage of health and safety programs, OSHA inspections, recordkeeping, and employer responsibilities. The course produces an OSHA 30 Department of Labor wallet card and is typically required for site supervisors, foremen, safety personnel, and self-employed contractors.
Anyone in a supervisory role on a U.S. construction site — foremen, superintendents, safety officers, project managers — and self-employed contractors bidding on public-works projects. Several states require it for supervisors on publicly funded projects; NYC's Local Law 196 requires OSHA 30 equivalency (via its Site Safety Training card) for supervisors on most construction sites.
Why Expiration Tracking Matters
Like OSHA 10, OSHA 30 cards do not carry a federal expiration date. Most general contractors expect a card issued within 3-5 years. NYC SST cards tied to OSHA 30 have specific freshness and refresher requirements. An expired-by-practice OSHA 30 card can pull a supervisor off site, halt work, and trigger compliance issues on publicly funded projects.
State & Federal Requirements
State rules mirror OSHA 10 requirements but elevate the bar for supervisors. NYC's Local Law 196 is the most prescriptive — requiring the Site Safety Training card anchored on OSHA 30 plus additional hours. Other states rely on general OSHA outreach rules. Always verify your trainer is OSHA-authorized.
Renewal Process
Retake the 30-hour course every 3-5 years or whenever a site or state requires refreshment. NYC SST has its own renewal cadence tied to 8-hour and 4-hour refresher courses. Replacement cards are available from the issuing trainer within 5 years.
Common Mistakes to Avoid
- Confusing OSHA 10 with OSHA 30 — supervisors typically need the longer course, not the entry-level one
- Letting an OSHA 30 card age past a general contractor's freshness policy without refresh
- Not tracking NYC SST refresher cadence separately from the underlying OSHA 30
- Using an unauthorized online course — only OSHA-authorized trainers issue valid DOL cards
