About This Quiz
Practise recognising common US construction hazards through 25 original multiple-choice questions. Review worker rights, the Construction Focus Four, safe equipment use, electrical hazards, access, excavations and emergency decisions. Explanations connect each answer to practical prevention rather than relying on recall alone.
Scope and independent practice
Independent practice material from HSEBlog, not an OSHA-authorized course, official examination or substitute for required training. Completing this quiz does not award an OSHA Outreach card, certification, licence or competent-person designation. The questions use federal US construction requirements in 29 CFR Part 1926 where specified; OSHA-approved state plans and individual tasks may impose additional requirements. Outreach is awareness education and does not replace training required by specific standards.
Study before you start
For each scenario, identify the hazard before choosing a control. Distinguish the six-foot threshold in the stated unprotected-edge provision from separate rules for ladders and scaffolds. Learn where a competent person's judgment and authority are required, and why defects, utility uncertainty and changing excavation conditions need prompt action. Use the linked OSHA sources and your employer's safe work procedures for further study.
Practice format
Answer 25 original multiple-choice questions, choosing one answer per question. The learning pass mark is 70%, with no time limit. Answers are shuffled, explanations are shown after submission and retakes are allowed. Use feedback to identify learning gaps, then review the source material before trying again. This practice score is not a qualification or an assessment of practical competence.
