What the OSHA 30 Hour Course Covers
The OSHA 30 Hour course is a 30-hour advanced safety training program developed by the Occupational Safety and Health Administration as part of the OSHA Outreach Training Program, designed to give workers a more in-depth understanding of workplace safety and health so they can better recognize, prevent, and address hazards on the job.
It covers key topics such as workplace hazards, employee rights, employer responsibilities, OSHA regulations, and safety management practices. Courses are offered for multiple industries, including Construction (covering standards under 29 CFR 1926) and General Industry (29 CFR 1910).
Upon completion, graduates are prepared to understand workers’ rights, employer responsibilities, and the importance of OSHA, as well as identify and describe common occupational hazards in their industry. Health and safety risks addressed include fire, electricity, falls, lockout/tagout, confined spaces, and more.
If you are a supervisor in any industry other than construction, agriculture, or maritime, OSHA considers you a general industry worker and recommends the OSHA 30 Hour General Industry course.
Construction vs. General Industry: Choosing the Right Track
Selecting the correct course track is essential before enrolling. The table below outlines the key differences:

The OSHA 30 Construction course covers the most common hazards of construction work, while the OSHA 30 General Industry course outlines a wide range of hazards that apply to most industries other than construction. Employers typically specify which version of the course you need.
How the Online Format Works
Taking an OSHA 30 Hour Online Course removes the scheduling barriers that classroom-based training often creates. The 30-hour course is authorized in all states for valid regulatory compliance, and learners can log in and out to train at their own pace.
For OSHA Online Outreach training programs, students must spend at least the required time taking the online course — 30 hours (1,800 minutes) for the 30-hour track — and the student may not spend more than 7.5 hours per day on the course.
For successful achievement, the student must pass all OSHA tests in the course and the final exam with a score of 70% or better in three attempts or less. OSHA requires that both the Outreach course and the end-of-course survey be completed within six months of starting the course; if these requirements are not met within the required timeframe, a Department of Labor (DOL) card will not be issued.
According to the OSHA Outreach Training Program overview, between FY 2021 and FY 2025, more than 6.51 million workers were trained in job hazard recognition and avoidance through the program — a figure that reflects how central this training has become to American workplace safety culture.
Corporate accounts and discounted group rates are also available for organizations registering five or more people for an online course.
Why the OSHA 30 Card Matters for U.S. Workplaces
OSHA 30 training is intended for workers with supervisory or safety oversight responsibilities. It is often required by employers, jobsite contracts, unions, or local jurisdictions, especially for leadership roles — and while not universally required by OSHA itself, it is highly recommended and often expected for supervisory positions.
After completing the course and passing required exams, students receive an official Department of Labor (DOL) OSHA 30 card, which is accepted nationwide by employers and worksites.
OSHA.net provides training and educational materials focused on workplace health and safety, offering convenient certification programs including the OSHA 10 Hour Online Course, OSHA 30 Hour Online Course, and specialized safety training. Students also receive a free PDF study guide that can be downloaded and printed, serving as a companion resource throughout the course.
