OSHA 30-Hour vs 10-Hour: Which Course Do You Need?

The Core Difference

OSHA 10-Hour is designed for entry-level workers and covers basic safety awareness. OSHA 30-Hour is designed for supervisors, foremen, and safety managers, providing a more in-depth look at safety and health hazards, regulations, and responsibilities.

OSHA 10-Hour: For Workers

If you are a general construction or general industry worker — laborer, carpenter, electrician, welder, or similar — OSHA 10-Hour is typically what you need. It satisfies requirements in most states that mandate training for workers.

OSHA 30-Hour: For Supervisors

If you are a foreman, site supervisor, safety officer, project manager, or contractor, OSHA 30-Hour gives you the deeper training needed to keep your crew safe and maintain compliance. New York City specifically requires OSHA 30-Hour for designated site safety managers.

Cost Comparison

OSHA 10-Hour courses typically cost $59–$89. OSHA 30-Hour courses range from $159–$200. Both include a DOL card upon completion and a digital certificate immediately after passing.
