OSHA 10-Hour Construction

The real 10-hour course covers 9 modules built around the Focus Four hazards, falls, electrocution, struck-by, and caught-in or -between, plus personal protective equipment, health hazards like silica dust and noise, materials handling, and hand and power tool safety, all built on real OSHA citation data from actual jobsites. It also covers the basics of the standard the course draws from (29 CFR 1926), plus workers' rights: the right to a safe workplace, the right to file a complaint without retaliation, and the right to see your own injury and illness records.

Structurally, it's not one long lecture with a single test at the end. Each module has its own short quiz (a 70% score to move on), and the course wraps with a comprehensive final exam pulling from every module, also scored at 70% to pass, with up to three attempts allowed and the whole course completed within 180 days. There's no minimum age to take it, the completion card doesn't expire, and it's issued by your OSHA-authorized trainer, not OSHA itself, usually within 90 days of finishing.

The real value in preparing for OSHA 10 isn't memorizing trivia, it's building the habit of actually noticing hazards before they hurt someone. That said, a few things are worth deliberately studying rather than assuming you already know: the specific numbers (fall protection thresholds, trench depths, noise limits) tend to differ from what feels intuitive, and the real exam likes to test whether you know a number applies in one context but not another, like fall protection kicking in at 6 feet on a typical site but 10 feet on a scaffold. Reviewing the Focus Four hazards until you can name all four without hesitating, and paying close attention to any place the course draws a line between "general construction" and a more specific situation (scaffolds, steel erection, excavation), covers a disproportionate share of what actually shows up on both the module quizzes and the final.

OSHA 10 isn't federally required for every private construction job nationwide, but treating it as optional is a mistake in practice: most general contractors and staffing agencies require it before they'll let anyone on a jobsite, and a handful of states have made it a legal requirement rather than just a hiring preference. Missouri requires it within 60 days of starting on a public works project, Nevada requires every construction worker statewide, public or private, to have it within 15 days of hire, and New York, Connecticut, Massachusetts, New Hampshire, Rhode Island, and West Virginia all require it on public or publicly funded construction above specific dollar thresholds, Massachusetts has the lowest threshold in the country at just $10,000. Requirements like these change over time, so it's worth confirming directly with an employer or state labor department rather than assuming a state's rule, or lack of one, still matches what's written somewhere online.

Course cost varies by delivery format more than by provider: an online OSHA 10 course typically runs somewhere in the $60 to $80 range, while an in-person class with a live instructor usually costs $200 to $300, reflecting the cost of a classroom and instructor time rather than a difference in what's actually taught. Either way, the only cards that count are the ones issued through an OSHA-authorized trainer; OSHA has publicly warned about fraudulent "cards" sold online that were never actually earned through a real course, so it's worth confirming a provider is legitimately authorized before paying for anything.

The practice questions below are original, written to test the same kind of hazard-recognition judgment the real exam does, not a copy of any real OSHA question.
