OSHA 30-Hour Training: The Supervisor Guide
If the OSHA 10 is for the crew, the OSHA 30 is for the people responsible for the crew. It goes deeper into hazard control and the supervisor role. Here is what it covers and who needs it.
QUICK ANSWER
OSHA 30-Hour training is the expanded Outreach course for supervisors, foremen, and workers with safety responsibility. It covers the same hazard categories as the OSHA 10 but in far greater depth, plus additional topics such as managing safety programs and controlling hazards. Like the OSHA 10, it is an awareness-level card, not a certification, but it is widely expected of site leadership.
Who the OSHA 30 Is For
The 30-Hour course targets people who direct the work: supervisors, foremen, safety coordinators, and lead workers. Because these roles decide how hazards are controlled, the course spends more time on prevention and program management, not just recognition.
How It Differs From the OSHA 10
- Depth: the same hazard categories, covered in much more detail.
- More topics: additional standards and managerial subjects the 10-Hour omits.
- Audience: written for people accountable for others safety, not only their own.
- Expectation: many general contractors require a percentage of on-site leadership to hold the 30.
Leadership
The 30-Hour reflects a simple truth: the person who controls how work is done needs deeper safety knowledge than the person doing a single task.
Like the 10, the 30 is awareness-level and does not replace hands-on, job-specific training. It pairs naturally with the crew-level OSHA 10-Hour course and the specific standards in our OSHA requirements checklist.
WE BUILD THIS IN VR — THE PRIME VR
We build your supervisor and safety-lead training into VR, so leaders practice hazard control and emergency decisions in realistic scenarios. It turns a 30-hour course into judgment they can prove, with performance data for every decision.

Who should take the OSHA 30 instead of the OSHA 10? +
Supervisors, foremen, safety coordinators, and anyone responsible for the safety of others should take the 30-Hour course. The 10-Hour is aimed at entry-level workers responsible mainly for their own safety.
Does OSHA 30 expire? +
OSHA does not set a federal expiration for the card, but many employers and states require periodic renewal, often every three to five years. Follow the requirement of the site or state where the work is performed.
Is OSHA 30 legally required? +
OSHA does not universally mandate it, but some states and many general contractors require a portion of site leadership to hold it. It functions as an expected baseline for supervisors more than a universal legal mandate.
