OSHA 10 vs. OSHA 30: Which Card Do You Need?
A job posting says "OSHA card required" and you are not sure which one. This guide answers which OSHA card you need based on the work you actually do.
Start with the job, not the course
If you are asking "which OSHA card do I need," the most reliable answer is sitting in your offer letter, job posting, union rules or subcontract. Employers, general contractors and some state or local governments specify the card they want. When a requirement exists, it settles the question, so check it before you spend ten or thirty hours on the wrong course.
If nothing is specified, use the rest of this guide. It is written from a worker's point of view. If you are the one buying training for a crew, our employer's guide to OSHA 10 and OSHA 30 covers budgeting and rollout instead.
The two cards side by side
| Feature | OSHA 10 | OSHA 30 |
|---|---|---|
| Who it is aimed at | Entry-level and front-line workers | Supervisors and workers with safety responsibility |
| What you learn | Recognizing and avoiding common hazards, your rights | The same, in more depth, plus controlling hazards and leading safe work |
| Minimum time | 10 contact hours, usually over two days or more | 30 contact hours, usually over four days or more |
| Versions | Construction or general industry | Construction or general industry |
| What you receive | Department of Labor Outreach completion card | Department of Labor Outreach completion card |
OSHA limits Outreach training to 7.5 contact hours per day, which is why neither course can be finished in a single day.
Which card fits your role?
Use this rule of thumb: if you do the work, OSHA 10; if you direct the work, OSHA 30.
Pick OSHA 10 if you are…
A new hire, laborer, helper, apprentice, machine operator, warehouse associate, or anyone getting formal safety training for the first time. The course gives you a solid foundation in recognizing hazards such as falls, electrical sources, struck-by dangers and chemical exposure, and it explains what your employer owes you. Our OSHA 10 training page describes the topics in detail.
Pick OSHA 30 if you are…
A foreman, crew lead, superintendent, shift supervisor, safety coordinator, or someone who has just been promoted and now tells others how to work. You will make decisions that affect other people's safety, and the longer course is built for that. See OSHA 30 training for supervisors for what it covers.
The promotion trap
A common mistake is assuming that the OSHA 10 card you earned as a laborer still fits after you become a lead. It does not expire, but it was not designed for someone responsible for a crew. If you now direct work, OSHA 30 is usually the better match, and some employers will require it.
Construction or general industry?
Each card comes in two versions, and taking the wrong one is the easiest way to waste your time. Choose based on the hazards of the work, not the company name on your paycheck.
Construction covers building, renovation, demolition, roadwork, utility installation and similar jobs governed by OSHA's 1926 standards. General industry covers manufacturing, warehousing, distribution, healthcare, retail and most fixed-site workplaces under the 1910 standards. A maintenance technician at a plant takes general industry; the contractor's crew building an addition onto that plant takes construction. If your work crosses both, ask your employer which they will accept.
What your card does and does not prove
The DOL card shows that you completed an OSHA Outreach Training Program course. OSHA is clear that it is not a certification or license. It does not make you "OSHA certified," and it does not qualify you to operate a forklift, enter a confined space or work at height. Those require separate task-specific training from your employer.
Federal OSHA does not put an expiration date on the card. However, some employers, unions, project owners and state or city rules ask for refresher training after a set number of years. Keep your card somewhere safe, and keep a photo of it; replacements can only be requested through the trainer or provider who issued it, and not indefinitely.
Before you enroll, check these
- The exact card your employer, union or contract asks for, including the industry version
- That the trainer or online provider is OSHA-authorized to issue Outreach cards
- How and when the card is delivered after you finish
- Whether your employer will pay for the course or schedule it as a group
- Whether a state or city rule where you will work adds its own requirement
Online or in a classroom?
Both formats can produce a legitimate card if the provider is authorized. Online is convenient when you need flexibility around a current job. A live class gives you an instructor who can answer questions about your trade and real examples from sites like yours. If your employer is arranging training for a whole crew, an onsite class at the workplace is often the simplest route, since everyone hears the same material and finishes together.
Worker questions about OSHA cards
Do I need OSHA 10 before I can take OSHA 30?
No. OSHA 30 is a standalone course. Some people take OSHA 10 first as an introduction, but it is not a prerequisite.
Is OSHA 30 "better" on a resume?
It shows more training hours, but the right card is the one that matches your role. Hiring managers for laborer positions usually ask for OSHA 10.
Can I get the card in one day?
No. OSHA caps Outreach training at 7.5 contact hours per day, so any offer of a same-day OSHA 10 card should make you suspicious.
My card is old. Do I need to retake it?
Federal OSHA does not require it, but check with your employer, union or the project, since some ask for a refresher after a certain number of years.
Does the card cover all the training my job requires?
No. It is awareness training. Your employer still owes you training on the specific hazards and equipment of your job.
