OSHA Training FAQ

What's the difference between OSHA 10 and OSHA 30?

OSHA 10 is entry-level awareness training for workers; OSHA 30 is more in-depth, aimed at supervisors and workers with safety responsibility.

Construction or General Industry — which do I need?

Construction covers building and site work; General Industry covers manufacturing, warehousing, and most other workplaces. Your employer or state usually specifies which.

Does Paratissimus give me the official OSHA card?

No. The official U.S. Department of Labor OSHA 10/30-Hour completion card is issued only by authorized OSHA Outreach trainers. Paratissimus is study material to help you prepare.

Is there a passing score?

Outreach courses are training-based; where quizzes or tests apply, providers typically require around 70%. Requirements vary by provider.

Does the card expire?

DOL Outreach cards generally do not expire, though many employers and states require periodic refresher training.

Do I need OSHA training?

Many employers, states, and jobsites require it. Check your employer or state requirements.
