"Do I need OSHA 10 or OSHA 30?" is the most common question in construction training, and it sits on top of the most misleadingly sold product in the industry. So this article starts where most providers would rather not.
Where OSHA cards actually come from — and where they don't
OSHA 10 and OSHA 30 are not generic labels for any ten- or thirty-hour safety course. They are specific products of the OSHA Outreach Training Program: courses delivered by OSHA-authorized Outreach trainers, which end in a plastic Department of Labor card mailed to the student. That card is the thing a contract or a city law means when it says "OSHA 10 required." Nothing else counts as one.
BuildRight Academy is not an OSHA Outreach provider. We cannot issue OSHA 10 or OSHA 30 cards, and no certificate we sell is one. Our courses are built to OSHA standards and our certificates verify online by their own code — but "built to OSHA standards" and "a DOL card" are different things, and a training company that blurs that line is not one you should trust with anything else.
Why say this on our own blog? Because the confusion is profitable, and workers pay for it — literally, when they buy a lookalike "OSHA certificate" that a gate checker rejects, and in wasted mornings when a crew gets turned away at check-in over paperwork someone swore was equivalent. If a provider offers you "OSHA 10" and cannot name the authorized trainer behind the card, walk away. That rule protects you from us and everyone else.
Now, with the disclosure done, here is how to actually choose.
What OSHA 10 is
OSHA 10 is the entry-level Outreach course: ten hours of instruction on hazard recognition, workers' rights, employer responsibilities, and the major hazard categories — falls, electrocution, struck-by, caught-in-between. It comes in a Construction version and a General Industry version; tower and construction crews want Construction.
Two practical details people learn late:
- It cannot be done in one day. Outreach rules cap instruction at 7.5 hours per day, so a legitimate OSHA 10 takes at least two days, online or not. A provider promising the card in an afternoon is describing something that does not exist.
- The federal card does not expire. Some states, cities, and employers layer their own refresh requirements on top — five years is a common cycle where one exists — so treat "does my card need renewing" as a question about your jurisdiction and your contract, not about OSHA.
What OSHA 30 is
OSHA 30 is the supervisory-depth version: thirty hours, at least four days under the same daily cap, covering the same hazard categories plus safety program management, inspections, and the parts of the standards a person running work is expected to actually navigate. It is built for foremen, superintendents, safety leads, and anyone who signs off on how other people work.
The 30 does not outrank the 10 at the gate — it answers a different question. The 10 says "this worker has been oriented to the hazards." The 30 says "this person can be responsible for other people around those hazards."
Who actually requires which card — usually not OSHA
Here is the second honest surprise: for most private-sector work, OSHA itself does not require anyone to hold an Outreach card. The program is voluntary at the federal level. The requirement almost always comes from somewhere closer to your paycheck:
- States and cities. A growing list writes OSHA 10 into law for construction workers, especially on public projects — New York City's site safety law is the loudest example, with several states running similar rules. If you work where such a law applies, the card is not optional and no substitute exists.
- General contractors and carriers. Contract language routinely demands OSHA 10 for all field personnel and OSHA 30 for site supervision. This is where most tower crews meet the requirement — it arrives via the GC's checklist, not a regulation. The same checklists also carry topic lines the card does not cover, like the ones on AT&T scopes.
- Employers. Many simply require the 10 as a hiring floor because their clients audit for it.

The rule of thumb the industry actually runs on: 10 for the field, 30 for whoever runs the field. If you are new, get the 10. If you direct work, sign JSAs, or want the foreman path — plan on the 30 before the title shows up, because by the time the promotion is offered, "has his 30" is often already on the list of prerequisites.
What our certificates are for, then
If the DOL card is the broad orientation, topic certificates are the specific proof — and gates check for both, on different lines of the same checklist.
An OSHA card does not tell a site that you are trained on fall protection this year, or RF awareness, or lockout/tagout, or first aid. Carrier and GC checklists ask for those by topic, per worker, with current dates. That is the half we build: focused courses — fall protection, RF awareness, lockout/tagout, first aid/CPR, and the rest of the catalog — each ending in a certificate of completion that a checker can verify online by its code in seconds. Same-day, two-year validity, built to OSHA standards, and honestly labeled as what they are.
A typical tower crew package is therefore two-layered: an Outreach card per person where contracts or laws demand it, plus the topic certificates the site checklist enumerates. Neither layer substitutes for the other. Anyone who tells you a topic certificate replaces a legally required DOL card is wrong, and anyone who tells you a DOL card covers the topic lines is wrong in the other direction.
The decision, in checklist form
- New to construction or telecom, no card: take OSHA 10 (Construction) from an OSHA-authorized Outreach provider, then stack the topic certificates your first employer's checklist names. Our first-year guide walks the whole entry package.
- Foreman, super, safety lead — or heading there: OSHA 30, plus the same topic lines as your crew, because the ratios count you too.
- Card current, but the gate wants RF or fall protection or first aid: those are topic lines. The card cannot answer them; a verifiable topic certificate can, same day.
- Not sure what your contract requires: ask the GC for the site checklist before buying anything, from anyone. One email saves guesswork in both directions.
Straight answers
Does an OSHA card expire?
Federally, no. Jurisdictions and employers may impose refresh cycles — check the rule where you work, not a forum thread.
Is online OSHA 10 legitimate?
Yes, when — and only when — it is delivered through an OSHA-authorized online Outreach provider and ends in a DOL card. The daily-hours cap still applies, so it still takes at least two days.
Is BuildRight OSHA-approved?
No provider's course is. Outside the Outreach program, OSHA does not approve, accept, or certify training. Our courses are built to OSHA standards, and what you receive is a certificate of completion that verifies online by its own code. Whether it satisfies a given site is the employer's or site owner's call — which is why the site checklist, not marketing copy, should drive every purchase.
