OSHA 10 vs OSHA 30: what's the real difference?

Last updated 2026-07-09

What are OSHA 10 and OSHA 30, exactly?

Both cards come from OSHA's Outreach Training Program, which has run since 1971 ^[1]. OSHA doesn't teach the classes. It authorizes private trainers, called Authorized Outreach Trainers, to deliver the courses and issue cards through one of OSHA's designated Training Institute Education Centers. The trainer applies, gets authorized, and renews on a schedule.

OSHA 10 is a 10-hour course. OSHA 30 is a 30-hour course. That's the obvious difference, and it tells you more than you'd think. The extra 20 hours in the 30 aren't padding. They reflect a different audience: someone responsible for other people's safety, more than their own.

Both courses come in two versions. Construction ties to 29 CFR 1926. General Industry ties to 29 CFR 1910 ^[2]. You pick the one that matches your work. A framing carpenter takes Construction. A warehouse supervisor takes General Industry. Taking the wrong version won't get your card pulled, but you'll sit through hours of content that doesn't touch your job.

Finish a legitimate course and you get a wallet-sized OSHA Outreach card. It comes from the OSHA Training Institute, not the trainer, and it takes a few weeks to arrive. Some trainers hand out a completion certificate the same day as a placeholder. That certificate is fine to show an employer while you wait. The physical card is what matters for contract compliance.

What topics does OSHA 10 cover vs OSHA 30?

OSHA locks in the mandatory topics for each course and lets trainers pick from a list of electives for the remaining hours ^[1]. The mandatory content is fixed. The electives flex.

Construction OSHA 10 requires an introduction to OSHA (your rights, employer responsibilities, how to file a complaint) plus the Focus Four: electrical hazards, fall protection, struck-by, and caught-in/between. OSHA calls them the Focus Four because they account for roughly 60% of construction deaths each year ^[3]. Fall protection alone is the single deadliest hazard on a construction site. The leftover hours can cover scaffolding, PPE, or materials handling, depending on the trainer.

Construction OSHA 30 keeps all of that and adds a stack more: health hazards in construction, stairways and ladders, cranes and rigging, excavation and trenching, concrete and masonry, and fire protection. It also spends real time on management work. How to run a job hazard analysis. How to lead a toolbox talk. OSHA's recordkeeping rules under 29 CFR 1904 ^[11]. How an inspection actually unfolds.

General Industry splits the same way. OSHA 10 GI covers walking and working surfaces, exit routes, fire protection, electrical basics, hazard communication under 29 CFR 1910.1200 (the hazard communication standard) ^[7], and PPE under 29 CFR 1910.132 ^[10]. OSHA 30 GI adds machine guarding, lockout tagout under 29 CFR 1910.147 ^[8], bloodborne pathogens, ergonomics, and a section on safety and health management programs.

Here's the cleanest way to hold the difference in your head. OSHA 10 teaches workers to spot hazards and know their rights. OSHA 30 teaches supervisors to control those hazards and run a program.

Topic Area	OSHA 10	OSHA 30
Worker rights and OSHA overview	Yes	Yes
Focus Four hazards (construction)	Yes	Yes, in depth
Fall protection	Yes	Yes, expanded
Electrical safety	Yes	Yes, expanded
Recordkeeping (29 CFR 1904)	No	Yes
Job hazard analysis	No	Yes
OSHA inspection process	Brief	Detailed
Trenching and excavation	Elective	Required
Cranes and rigging	No	Required
Safety management programs	No	Yes

How long does each course take, and can you do it online?

OSHA 10 takes at least 10 contact hours. OSHA 30 takes at least 30. OSHA's Outreach rules require in-person courses to spread those hours across multiple days, so you can't cram 30 hours into one marathon weekend ^[1].

Online is where the rules get sharper. OSHA authorized online delivery for both courses, but with a hard deadline: online OSHA 10 has to be finished within 6 months, and online OSHA 30 within 12 months ^[1]. Miss the window and you lose your progress and start over. That trips up plenty of people who buy a course, do three hours, and forget about it until spring.

Not every online platform is real. OSHA requires online courses to run through an OSHA-authorized online trainer, more than any e-learning company that pasted an OSHA logo on its checkout page. You can confirm an authorized online trainer through OSHA's Training Institute Education Centers ^[1]. If a site can't name which Education Center authorized it, walk away.

Prices vary because OSHA sets no floor. In-person OSHA 10 usually runs $100 to $200 per person, and in-person OSHA 30 runs $250 to $500. Online tends to cost less: roughly $60 to $100 for OSHA 10 and $150 to $250 for OSHA 30. These are market ranges pulled from publicly listed prices across multiple authorized trainers, and your number depends on whether you enroll solo or grab a group rate.

Employers often cover osha 30 training as a condition of a supervisory role. That's money well spent. The card is good for life. OSHA 30 doesn't expire, though plenty of employers and contractors expect refresher training every few years as a practical matter.

Who should get OSHA 10 and who should get OSHA 30?

Short version: workers get the 10, supervisors get the 30.

OSHA's own guidance describes OSHA 10 as intended for "entry-level workers" and OSHA 30 as designed for "supervisors or workers with some safety responsibility" ^[1]. If the job is doing the work, OSHA 10 fits. If the job includes telling others how to work safely, scheduling tasks, signing permits, or running inspections, that person belongs in OSHA 30.

In construction, a laborer or apprentice electrician takes the 10. A foreman, superintendent, or site safety coordinator takes the 30. General industry runs the same logic. A machine operator takes the 10. A shift supervisor or facilities manager takes the 30.

Nothing stops a worker from taking the 30. Some pursue it for career reasons, and some contractors prefer it across the board. But don't require OSHA 30 for every single employee on a site. That's an expensive use of training time and not what the course was built for.

If you're managing osha training across a workforce, use this split. Identify anyone who can stop work, assign tasks, run safety meetings, or sign off on permits. Those people get the 30. Everyone else gets the 10. That maps straight onto how OSHA designed the program.

Is OSHA 10 or OSHA 30 required by law?

This is where the confusion lives. Neither OSHA 10 nor OSHA 30 is universally required by federal OSHA regulations ^[4]. The standards in 29 CFR 1910 and 29 CFR 1926 require employers to train workers on specific hazards, but they never name the Outreach card as the way to do it. You can satisfy those training duties through other means.

The card does become mandatory in a few real situations.

Several states have laws requiring OSHA 10 or OSHA 30 for construction workers. New York's Labor Law Section 220-h requires OSHA 10 for workers on public works construction projects ^[5]. Massachusetts has a similar rule for public building construction ^[12]. Connecticut requires OSHA 10 for workers on public construction projects over $100,000. Nevada, Missouri, New Hampshire, and Rhode Island run their own versions. The details differ by state, so check the rules wherever you're building.

Federal contracts and project labor agreements often require OSHA 30 for foremen and OSHA 10 for workers even when no statute forces it. The U.S. Army Corps of Engineers has long written Outreach card requirements into its contract specifications. Bidding on public construction? Read the spec book before you assume anything about training.

Some insurance carriers and general contractors require the card just to set foot on site. That's a business requirement, not a legal one, but the effect is identical: no card, no work.

For most private-sector workplaces outside state-mandated industries, OSHA 10 and 30 are voluntary. Voluntary doesn't mean pointless. Trained supervisors are one of the clearest ways to show good faith during an OSHA inspection, which shapes how citations get classified and whether penalties come down ^[4].

Which states require OSHA 10 or OSHA 30 for construction?

State requirements shift, so treat this as a starting point and confirm with your state labor department before you sign a contract. Six states carry the clearest public-works mandates.

New York requires OSHA 10 for all workers on public works construction projects under Labor Law 220-h ^[5]. The law defines "public work" broadly, and a violation can get a worker pulled off the site.

Massachusetts requires OSHA 10 for all workers on state-funded public building construction projects under M.G.L. Chapter 149, Section 133 ^[12]. It applies to general contractors and subcontractors alike.

Connecticut requires OSHA 10 for workers on public works contracts over $100,000 under CGS Section 31-53b. The card requirement itself is immediate, though the statute built in a grace period before certain penalties kick in.

Nevada requires OSHA 10 for construction workers on public works under NRS 618.475, aimed at workers who have been in the trade fewer than five years.

Missouri requires OSHA 10 for workers on certain public construction projects through state law. New Hampshire and Rhode Island carry similar mandates for public building work.

None of these states require OSHA 30 by statute for rank-and-file workers, though contracts and project labor agreements inside those states often do require it for supervisors.

One more layer. If you operate in a state with its own OSHA plan (there are 28 of them, covering either the full private and public workforce or just public-sector workers), check whether that state plan adds training requirements. California's Cal/OSHA, for one, has training standards that push past the federal minimums in several areas.

How much does OSHA 10 cost compared to OSHA 30?

Across publicly listed authorized trainers, OSHA 10 runs roughly $60 to $200 per person and OSHA 30 runs roughly $150 to $500, with format (online vs in-person) and group rates driving the spread. Online usually lands at the low end. In-person sits at the top.

Group discounts are common. Many trainers will cut a per-head price for a company sending 10 or 20 workers at once. If you're onboarding a full crew before a public works job, that's a conversation worth starting.

The physical wallet card is bundled into the course fee. There's no separate OSHA card charge.

Watch for fakes. Some sites sell what look like OSHA cards for $20 or $30 with almost no training behind them. Those aren't legitimate Outreach cards, and OSHA has posted warnings about fraudulent ones ^[1]. A real OSHA 10 card carries a serial number, comes from the OSHA Training Institute, and can be verified. If you're an employer taking cards from new hires, learn what a real one looks like.

For osha 30 hour online course options, the price usually beats in-person, but confirm the provider is authorized before you pay.

Does OSHA 10 or OSHA 30 expire?

Neither card officially expires. OSHA sets no renewal period for the 10 or the 30 ^[1].

There's a catch, though. State laws, contracts, and employers set their own renewal expectations. Contractors on New York public works frequently read the rule to require a card from within the last five years, and the federal contractor world often applies a similar standard informally even where no statute demands it.

OSHA recommends workers refresh their hazard awareness regularly but doesn't tie that to the Outreach card. The training requirements that actually carry weight in a compliance review are the hazard-specific ones. Fall protection training under 29 CFR 1926.503, for example, has to happen before a worker faces a fall hazard, with no fixed expiration but a firm requirement to retrain whenever the employer has reason to believe a worker doesn't understand the material ^[6].

Here's the honest take. Treat the card as evidence of foundational training, not a stand-in for ongoing, task-specific training. A worker who earned an OSHA 10 card five years ago and hasn't had a safety conversation since is not a trained worker in any way that counts.

What's the difference between OSHA 10 and OSHA 30 for construction vs general industry?

The construction version references 29 CFR 1926, the construction safety standards. The general industry version references 29 CFR 1910, the general industry standards ^[2]. Beyond that regulatory backbone, the hazard topics split hard.

Construction courses spend real time on fall protection, scaffolding, trenching, struck-by hazards, and cranes. That reflects the numbers. The construction sector had a fatal injury rate of 9.6 per 100,000 full-time equivalent workers in 2022, more than double the all-industry rate of 3.7 ^[3].

General industry courses lean toward machine guarding, confined spaces, lockout/tagout, chemical hazards, and ergonomics. A manufacturing plant, a warehouse, and a restaurant carry different risk profiles than a construction site, and the curriculum follows those risks.

Work in both worlds? Take the version that matches your primary exposure. Some employers send supervisors through both, but that's unusual and never required.

Workers in shipbuilding, maritime, or agriculture have separate Outreach programs. The Construction and General Industry tracks don't cover those environments well enough to rely on.

One more note. forklift certification is a separate requirement under 29 CFR 1910.178 and is not covered by OSHA 10 or OSHA 30 ^[9]. An Outreach card does nothing to satisfy the powered industrial truck training requirement.

How does OSHA 10 or 30 affect an OSHA inspection or citation?

Cards won't immunize you from citations. Inspectors cite based on hazard conditions on the ground, not on whether training cards exist in a drawer.

Training documentation still matters, in two ways.

First, several OSHA standards require training outright, and the Outreach card can serve as part of your proof that training happened. If an inspector asks for training records on hazard communication under 29 CFR 1910.1200 ^[7] or fall protection under 29 CFR 1926.503 ^[6], an OSHA 10 or 30 card is supporting evidence, not a full record. You still have to document the specific hazards workers were trained on, the date, and the trainer's qualifications.

Second, good faith factors into penalty math. OSHA's Field Operations Manual treats good faith as a basis for reducing the initial penalty, typically by up to 25% ^[4]. Documented training, including Outreach training, backs a good-faith argument. An employer who can show supervisors completed OSHA 30 and workers completed OSHA 10 before a hazard turned up is in a far better spot than one with no records at all.

Building a full safety program and need a starting point? SafetyFolio's safety program generator produces a customized written program in about 15 minutes, which gives you the documentation backbone OSHA expects to see next to your training records.

For how incident report requirements interact with citations, that's a separate topic worth learning before your first inspection.

OSHA 10 vs OSHA 30: which one is worth it for your business?

If you're a small business owner deciding how to spend a limited training budget, here's my honest take.

For any supervisor, lead, or foreman: OSHA 30 is worth it. The extra 20 hours give them a real framework for treating safety as a management job instead of a checklist. That pays off in fewer incidents, better documentation habits, and a stronger footing if OSHA ever shows up. At $250 to $500 per supervisor, it's one of the better training buys you can make.

For hourly workers on a public works project in a mandate state: OSHA 10 is required. No card, no work. Build it into your bid.

For hourly workers in a private-sector general industry job with no contract requirement: OSHA 10 is a solid baseline, but don't mistake it for a complete training program. The hazard-specific training required by 29 CFR 1910 standards still has to happen. OSHA 10 supplements that training. It never replaces it.

For small shops choking on the cost: you can meet OSHA's training requirements without Outreach cards, because the standards don't require them. What they require is documented, competent training on the actual hazards in your workplace. Prove that another way and the card is optional. But the card is a recognized, portable credential that workers value and that many clients and GCs expect. That carries real business value.

The full picture on osha compliance runs well past training cards. Written programs, hazard assessments, recordkeeping, and incident investigation all sit alongside training as core parts of what OSHA expects.

SafetyFolio's program generator is one way to get those written programs built without paying thousands to a consultant.

Frequently asked questions

Can I take OSHA 30 without first taking OSHA 10?

Yes. OSHA doesn't require you to finish OSHA 10 before taking OSHA 30. The 30-hour course covers all the foundational content from the 10 and then goes deeper. Some people take the 10 first as a preview, but it's not a prerequisite. If you're a supervisor and your employer is paying for one course, skip the 10 and go straight to the 30.

Is OSHA 10 the same as OSHA 10-hour training?

Yes. OSHA 10 and OSHA 10-hour training mean the same thing: the 10-hour course in OSHA's Outreach Training Program. The terms get used interchangeably. The official program name is OSHA Outreach Training, and the 10-hour version gets shortened to OSHA 10. The card it produces is sometimes called an OSHA 10-hour card.

How long does it take to get the actual OSHA card after completing the course?

Expect four to six weeks from course completion to the wallet card arriving by mail. The trainer submits your completion info to the OSHA Training Institute, which issues and mails the cards. Many trainers give you a same-day certificate of completion to show an employer while you wait. That certificate doesn't replace the card for contract compliance, but it does document that you finished.

Does OSHA 10 or OSHA 30 count as site-specific safety training?

No. Both courses give general hazard awareness, not site-specific training. Most job sites and OSHA standards require a site-specific orientation covering that location's particular hazards, emergency procedures, and safety rules. An Outreach card supports that orientation but never replaces it. You still document site-specific training separately from the card.

What is the difference between OSHA 10 and OSHA 30 for general industry workers?

OSHA 10 General Industry covers worker rights, walking and working surfaces, fire protection, electrical basics, hazard communication, and PPE in about 10 hours. OSHA 30 General Industry adds lockout/tagout, machine guarding, confined spaces, bloodborne pathogens, ergonomics, and safety program management. The 30 targets supervisors who have to understand and administer those programs, more than follow them.

Can an employer get fined if workers don't have OSHA 10 or OSHA 30 cards?

In most private-sector workplaces, no. Federal OSHA doesn't require the Outreach card. Employers can be cited for failing to train workers on specific hazards under the relevant 29 CFR standard, but the absence of an Outreach card alone is not a citable violation. In states with public works mandates like New York, workers without cards can be pulled off the site, which hits contractors financially even without a direct OSHA fine.

Are OSHA 10 and OSHA 30 accepted in all 50 states?

The Outreach card is recognized nationally and in most international settings where OSHA standards apply. States with their own OSHA plans may add training requirements on top of the federal program, but they generally accept the card. States without their own plans run under federal OSHA, which doesn't require the card at all but recognizes it as documentation of training.

What happens if someone's OSHA 10 or OSHA 30 card is lost?

Contact the trainer or the OSHA Training Institute Education Center that processed your completion. Replacement cards are available, usually for a small fee and some processing time. A certificate of completion helps establish the record. Keep a digital copy of your card and certificate once you have them. OSHA's system does hold records, but retrieval goes faster when you have your original trainer's information.

Does online OSHA 10 or OSHA 30 carry the same weight as in-person training?

For card validity and contract compliance, yes. An online OSHA 10 or 30 completed through an authorized provider produces the same wallet card as an in-person course. That said, some employers and GCs prefer in-person, and some contracts require it. Learning quality also varies, since hands-on demonstration of certain skills is easier in a room. Check your contract language before you pick a format.

What's the difference between an OSHA 10 card and an OSHA 30 card visually?

Both cards run similar in size and format, issued by the OSHA Training Institute. The card lists the number of hours (10 or 30), the industry track (Construction or General Industry), the completion date, and a serial number. Background color and layout have changed over the years as OSHA updated its designs. The serial number lets you verify authenticity with the issuing Education Center.

Is the OSHA 30 worth it for a small business owner who works in the field?

Usually yes, especially in construction or if you're a working owner who also supervises. OSHA 30 gives you a usable framework for running toolbox talks, doing basic job hazard analyses, and understanding what inspectors look for. It's 30 hours of your time and $250 to $500. For a business where one serious injury could cost tens of thousands in workers' comp and lost production, that's a reasonable buy.

Can a supervisor have only an OSHA 10 and still meet OSHA requirements?

In most cases, yes, because OSHA doesn't require the 30-hour card for supervisors. What the standards require is that supervisors be competent in the hazards they oversee, as defined in specific rules like 29 CFR 1926.32. Competency comes from knowledge and experience, not a specific card. Still, OSHA 30 is the clearest documented path to showing that competency, and many clients and GCs require it contractually regardless of the federal rule.

How do I verify that an OSHA 10 or OSHA 30 trainer is legitimate?

OSHA's Training Institute Education Centers keep directories of Authorized Outreach Trainers in their regions. Find the Education Centers through the OSHA website and contact them to verify a trainer's credentials. For online courses, the provider should clearly name which Education Center authorized it. If a provider can't answer that, look elsewhere. Fraudulent cards do circulate, and accepting fake cards on a site can expose employers to liability.
