Expert take: what OSHA 10 Construction really tests
OSHA 10 Construction is a voluntary 10-hour DOL Outreach awareness class, not a licence or certification. Many employers, unions and states require it anyway. Six of the hours are fixed: Introduction to OSHA, the Focus Four hazards (falls for at least 1.5 hours), PPE and health hazards. Online, you must pass module quizzes and a final exam of about 20 questions at 70%, and spend the full 10 hours, with no more than 7.5 hours per day. The card does not expire federally.
Preparation tips
- Master the Focus Four (falls, electrocution, struck-by, caught-in/between); they take 4 of the 10 hours and most of the questions.
- Learn the key trigger numbers: fall protection at 6 feet, trench protective systems at 5 feet, and a ladder or ramp within 25 feet in trenches 4 feet or deeper.
- Take each module quiz seriously. Attempts are limited, and failing them can lock you out of the course.
- Use only an OSHA-authorized online provider. Cards from unauthorized sites are not valid DOL cards.
Common mistakes to avoid
- Expecting to finish in one day. The 7.5-hour daily cap means a 10-hour class always takes at least two days.
- Treating the card as a licence or as OSHA-mandated training. It is voluntary awareness training that does not satisfy any specific OSHA standard.
- Mixing up the 6-foot construction fall trigger with the 4-foot general-industry and 10-foot scaffold thresholds.

- Electrocution: overhead power lines, GFCIs, grounding, and damaged cords and tools
- Struck-by and caught-in/between: vehicles, falling objects, trench cave-ins, rotating equipment
- PPE: hard hat types and classes, eye and face protection, hearing protection, respirators
- Health hazards: silica, noise, lead, heat and hazard communication labels
- Electives such as excavations, scaffolds, ladders, tools and materials handling
- Pass each module quiz at 70% before moving on
- Take the final exam (typically about 20 questions) at 70%, usually within three attempts
- Finish the course evaluation so the provider can issue your DOL card

Frequently asked questions
- What is the difference between OSHA 10 and OSHA 30 Construction?
- OSHA 10 is a 10-hour awareness class for entry-level workers, with 6 required hours and at least 2 elective hours. OSHA 30 is a 30-hour class for supervisors and workers with safety responsibility. It adds required time on managing safety and health, stairways and ladders, and longer PPE and health-hazard modules, plus at least 12 elective hours. Both lead to a DOL Outreach card.
- Does the OSHA 10 card expire?
- No. OSHA states that construction Outreach student course completion cards have no expiration date. Some employers, unions or state rules may still ask for refresher training.
- Is OSHA 10 required by law?
- Not by federal OSHA. The Outreach Training Program is voluntary and does not meet the training requirements of any OSHA standard. Some states, cities and employers require the card to work on certain jobsites.
- What topics are required in the OSHA 10 construction class?
- Introduction to OSHA (1 hour), the Focus Four hazards (4 hours: falls for at least 1.5 hours, plus electrocution, struck-by and caught-in-or-between for at least 30 minutes each), personal protective equipment (30 minutes) and health hazards in construction (30 minutes). At least 2 more hours come from electives such as excavations, scaffolds or ladders.
- What is the OSHA 10 online final exam like?
- With OSHA-authorized online providers, you pass a short quiz after each module and then a final exam, typically about 20 multiple-choice questions. Each needs at least 70%, usually within three attempts. Failing the third attempt can lock the course, and you would have to start over.
- Can I finish OSHA 10 in one day?
- No. OSHA limits Outreach training to 7.5 contact hours per day, so a 10-hour class takes at least two calendar days. Breaks and quizzes do not count toward the 10 hours.
- How do I replace a lost OSHA 10 card?
- Contact the trainer or online provider that ran your class. A replacement can be issued only if the class was completed within the last five years, and only one replacement is allowed per class.
