Workplace safety training is essential in high-risk industries such as construction, manufacturing, warehousing, and general industry. If your job requires OSHA safety training, you’ve likely heard about OSHA 10 and OSHA 30. While both courses fall under OSHA’s Outreach Training Program, they serve different purposes and audiences.
This guide explains OSHA 10 vs OSHA 30 in detail, including who each course is for, what they cover, how long they last, and whether you need both.
What Is OSHA Training?
OSHA stands for the Occupational Safety and Health Administration, a federal agency under the U.S. Department of Labor. OSHA created the Outreach Training Program to provide standardized safety education for workers and supervisors.
These courses are designed to:
- Increase hazard awareness
- Reduce workplace injuries and accidents
- Help employers meet job-site safety requirements
The Outreach program is divided into two levels:
- OSHA 10-Hour Training
- OSHA 30-Hour Training
Each level is available for different industries, including Construction and General Industry.

You Should Take OSHA 30 If:
- You supervise workers

Some states and job sites may require OSHA 30 even for non-supervisory roles, so it’s important to verify local requirements.
Is OSHA 10 Required Before OSHA 30
No. OSHA 10 is not a prerequisite for OSHA 30.
You can enroll directly in OSHA 30 if your job requires supervisor-level training, even if you have never taken OSHA 10.
Does OSHA 30 Cover OSHA 10?
Yes. OSHA 30 fully covers OSHA 10 content and expands on it in greater detail. This is why workers who have completed OSHA 30 generally do not need OSHA 10.
If You Have OSHA 30, Do You Need OSHA 10?
In most cases, no. OSHA 30 is widely accepted as a replacement for OSHA 10. Some states or employers specifically mention OSHA 10, but they usually accept OSHA 30 as an equivalent or higher qualification.
Do You Ever Need Both OSHA 10 and OSHA 30?
You do not need to take both at the same time. However:
- A worker may take OSHA 10 early in their career
- Later, they may need OSHA 30 after moving into a supervisory role
OSHA 10 training does not transfer hours toward OSHA 30. If required, the full OSHA 30 course must be completed.
Is the OSHA Certificate Different From the OSHA Card?
Yes, they are different.
- OSHA Certificate: Issued by the training provider as proof of course completion
- OSHA DOL Card: A wallet-sized card issued by the U.S. Department of Labor
Most employers require the OSHA DOL card, as it is the official credential.
How Long Is OSHA 10 or OSHA 30 Good For?
OSHA 10 and OSHA 30 do not officially expire. However:
- Employers may require refresher training
- Some states require renewal every 3 to 5 years
- Job sites may set their own validity rules
Always confirm local and employer requirements.
