Is OSHA 30 just OSHA 10 with more hours?

Not exactly. OSHA 30 covers more topics and goes deeper, with more emphasis on hazard prevention, controls, and the responsibilities of people who manage or supervise work. It is aimed at a different audience, not just a longer version of the same content.

Do OSHA 10 and 30 cards expire?

OSHA does not set a federal expiration for outreach cards, but many employers, states, and project owners require refresher training every few years. Follow whichever rule is strictest for your situation.

Does OSHA 10 or 30 make my workplace compliant?

No. These courses build awareness, but OSHA still requires specific, hands-on training for the actual hazards of each job, plus a real safety program. Training cards are one piece of compliance, not the whole thing.

OSHA 10 vs OSHA 30: Which Training Does Your Team Need?

By Continuum Improvement · Updated 2026-07-03

OSHA 10 and OSHA 30 are voluntary outreach training courses that teach workers to recognize, avoid, and prevent workplace hazards. They are not the same thing, and picking the right one for each role matters — both for safety and, in some states and contracts, for compliance.

Neither course is a substitute for the site-specific, hands-on training OSHA requires for the actual hazards of a job. They build a foundation; your safety program does the rest.

The core difference

OSHA 10 — a 10-hour course aimed at entry-level workers. It covers awareness of common hazards and workers' rights. Think "recognize the danger and know your rights."
OSHA 30 — a 30-hour course aimed at supervisors, foremen, and anyone with safety responsibility. It goes deeper into hazard prevention, controls, and program management. Think "prevent the danger and manage the risk."

Who needs OSHA 10

OSHA 10 fits new and frontline employees who need a broad awareness of the hazards around them: what to watch for, how to protect themselves, and how to raise a concern. It is a strong baseline for a whole crew.

Who needs OSHA 30

OSHA 30 is built for people who are responsible for others' safety — supervisors, site leads, safety committee members. The extra depth covers managing hazards, understanding controls, and the employer's responsibilities, which is exactly what a person directing work needs to know.

Construction (1926) vs General Industry (1910)

Both courses come in two versions, matched to the OSHA standards that apply to your work:

Construction follows 29 CFR 1926 and focuses on hazards like falls, electrocution, struck-by, and caught-in/between — the "Focus Four."
General Industry follows 29 CFR 1910 and covers manufacturing, warehousing, and most other non-construction workplaces.

Choose the version that matches the standards governing your worksite, not just the shorter or cheaper option.

Is OSHA 10 or 30 required?

Federally, these outreach courses are voluntary. But several states, municipalities, and project owners do require OSHA 10 or 30 cards for certain workers — especially in construction. Check your state rules and any contract requirements before you assume it is optional.
