The course requires a minimum of 30 hours. It is self-paced online — you can pause and resume anytime. DOL rules limit training to 7.5 hours per day — OSHA 10 takes a minimum of 2 days, OSHA 30 a minimum of 4 days. Once started, the course must be completed within 180 days.
What score do I need to pass OSHA 30?
