OSHA 10-Hour Outreach Training (Construction) Study Guide

The OSHA 10-Hour Outreach Training for Construction is a voluntary awareness program, not a licensing exam. There is no test to pass and no OSHA-set score — but the training itself runs on a strict, published structure that every authorized trainer must follow.

• 10 hours of instructional time is the required minimum for the course.
• Topics split into 6 required hours, 2 elective hours, and 2 optional hours.
• Classes must run across at least 2 calendar days — you cannot compress it into one long session.
• Class size is capped at 40 students and must have at least 3 students to count as an official Outreach class.
• Daily training is capped at 7.5 student contact hours per calendar day.
• Completion cards never expire for Construction Outreach, and trainers must issue cards within 90 days of course completion.

Memorize this hour breakdown first — it is the backbone of every topic-coverage question you'll see in practice material.

The Outreach blueprint divides content into required, elective, and optional topics, each with its own minimum time. The required block includes a 1-hour Introduction to OSHA (workers' rights, employer responsibilities, how to file a complaint), a 4-hour Focus Four Hazards block, a 30-minute Health Hazards in Construction segment, and a 30-minute Personal Protective Equipment segment.

• Introduction to OSHA — 1 hour minimum.
• Focus Four Hazards — 4 hours, covering the leading causes of construction fatalities.
• Health Hazards in Construction — 30 minutes minimum.
• Personal Protective Equipment (PPE) — 30 minutes minimum.

Beyond the required core, trainers must present at least two distinct elective topics (things like stairways/ladders, electrical safety, or excavations), and no single topic — required or elective — may consume more than 4 hours of the total course, with a strict floor of 30 minutes on any topic that is presented at all. That floor-and-ceiling rule is why the schedule feels tightly paced: trainers are threading a lot of mandatory ground into a fixed 10 hours.

The Focus Four are OSHA's name for the hazard categories responsible for the largest share of construction fatalities: falls, electrocution, struck-by incidents, and caught-in/between incidents. Because falls are consistently the single biggest killer on construction sites, the blueprint gives falls extra weight inside the Focus Four block.

• Falls must get a minimum of 1.5 hours (90 minutes) of coverage — more than any other Focus Four topic.
• The remaining three Focus Four topics — electrocution, struck-by, and caught-in/between — each need a minimum of 30 minutes.

When you're reviewing, don't just memorize hazard names — think about why falls get the largest time allocation. Fall protection involves guardrails, personal fall-arrest systems, safety nets, and ladder/scaffold procedures, which is simply more ground to cover than a single electrocution or caught-in/between hazard. Expect review material and practice questions to test whether you can match each Focus Four category to its real-world example (a worker on a roof without guardrails is a falls scenario; a trench collapse is caught-in/between), not just recite the category names.

This is the single most misunderstood fact about OSHA 10: there is no OSHA-required exam and no official passing score. Testing is not a requirement for Outreach classes at all. If a trainer chooses to give a quiz, that is entirely at their own discretion — OSHA sets no standard for it.

• OSHA does not require a test to earn the completion card.
• Whether a student has "successfully completed" the class is left to the individual trainer's judgment, not a fixed cutoff score.
• If a trainer does administer a test, that testing time does not count toward the required instructional contact hours — it's separate from the 10 hours of content.

Practically, this means you should treat any practice questions as a study aid for retention and workplace readiness, not as a pass/fail gate. Your actual goal is attendance and engagement across the full 10 hours, since that — not a score — is what earns the card. If a course provider tells you otherwise — say, requiring a minimum quiz score to hand out the card — that requirement is coming from the provider's own internal policy, not from any federal standard.

Once you finish the course, the completion card itself follows its own set of deadlines and limits — separate from anything about the training content.

• Trainers must issue your card within 90 days of the course completion date.
• Construction 10-hour cards do not expire, so once issued, you don't need to renew it to keep it valid.
• Lost your card? A replacement can be requested, but only if the original class was completed within the last 5 years — after that window, OSHA's system will not support issuing a new card for that class.
• Only one replacement card per student per class is ever issued — so keep the replacement in a safe place once you get it.
• If a new set of cards is needed because the originals never arrived, that request cannot be made more than 90 days after the class end date.

Because the card never expires, there's no recurring "renewal exam" to prep for as a student — this only applies to trainers, who face their own separate authorization renewal requirements.

Since there's no scored exam to "pass," the goal of studying isn't to hit a target number — it's to actually retain the safety information that keeps you and your coworkers alive on a job site. Use the practice questions on this page the way a good trainer would use a review session: as a way to surface gaps before they matter in the field.

• Work through Focus Four scenarios first. These hazards get the most instructional time for a reason — they're the leading causes of injury and death on construction sites.
• Pair PPE questions with real equipment. If you can name it, try to also picture when and how it's actually used.
• Don't skip Introduction to OSHA content. Questions about workers' rights and how to report hazards show up more often than people expect, precisely because trainers must cover this material.
• Review, don't cram. Because there's no single cutoff score, spacing your review across a few sessions builds the kind of durable recall that actually transfers to a job site — which is the entire point of the program.
