  1. OSHA 10-Hour Construction

    Which federal agency is responsible for enforcing workplace safety and health standards in the United States?

    Correct — D. OSHA, established under the Occupational Safety and Health Act of 1970, is the federal agency charged with setting and enforcing workplace safety and health standards, including those found in 29 CFR 1926 for the construction industry.
  2. OSHA 10-Hour Construction

    What is the primary purpose of the OSHA 10-Hour Construction Outreach Training Program?

    Correct — C. The OSHA 10-Hour Construction Outreach Training Program is designed to give entry-level construction workers basic awareness of job-site hazards, worker rights, and employer responsibilities — it is not a substitute for employer-provided, site-specific safety training.
  3. OSHA 10-Hour Construction

    Under OSHA regulations, workers have the right to receive safety training in a language and vocabulary they can understand. Which section of the Occupational Safety and Health Act establishes this worker right?

    Correct — C. Section 8 of the OSH Act grants workers the right to receive information about hazards and training in a language and vocabulary they can understand, while Section 11(c) separately protects workers from retaliation for exercising their safety rights.
  4. OSHA 10-Hour Construction

    Which construction standard code under the Code of Federal Regulations applies specifically to the construction industry?

    Correct — B. 29 CFR 1926 contains OSHA's safety and health regulations specific to the construction industry; 29 CFR 1910 covers general industry, 29 CFR 1904 covers recordkeeping, and 29 CFR 1915 covers shipyard employment.
  5. OSHA 10-Hour Construction

    The General Duty Clause (Section 5(a)(1) of the OSH Act) requires employers to do which of the following?

    Correct — A. Section 5(a)(1), the General Duty Clause, requires every covered employer to furnish a place of employment free from recognized hazards likely to cause death or serious physical harm, even when no specific OSHA standard addresses the hazard.
  6. OSHA 10-Hour Construction

    A construction worker believes there is a serious safety hazard on the job site and files a complaint with OSHA. Which of the following best describes the worker's protection under the OSH Act?

    Correct — B. Section 11(c) of the OSH Act prohibits employers from retaliating against workers who exercise their safety rights, including filing a complaint with OSHA; workers generally have 30 days to report retaliation to OSHA.
  7. OSHA 10-Hour Construction

    Under OSHA's recordkeeping requirements (29 CFR 1904), most employers with more than 10 employees must record work-related injuries and illnesses. Which form is used to log these incidents on an ongoing basis throughout the calendar year?

    Correct — B. OSHA Form 300 is the running log used to record each work-related injury or illness during the year; Form 300A is the annual summary posted February 1 through April 30, and Form 301 is the detailed incident report for each individual case.
  8. OSHA 10-Hour Construction

    During an OSHA inspection, the compliance officer asks to speak privately with workers. Which statement correctly describes a worker's rights during this process?

    Correct — C. Under Section 8(a)(2) of the OSH Act, OSHA compliance officers have the right to interview workers privately, and workers cannot be required by the employer to have a supervisor or company representative present during these interviews.
  9. OSHA 10-Hour Construction

    OSHA prioritizes its inspection activities in a specific order. Which type of hazard triggers OSHA's highest inspection priority?

    Correct — B. OSHA's inspection priority order places imminent danger at the top because the risk of death or serious injury is immediate, followed by severe injuries/fatalities, worker complaints, referrals, follow-ups, and planned programmed inspections.
  10. OSHA 10-Hour Construction

    An employer receives an OSHA citation. Which of the following statements about citation posting is correct under 29 CFR 1903?

    Correct — C. Under 29 CFR 1903.16, the employer must prominently post citations at or near each place the violation occurred for three working days or until the hazard is corrected, whichever is longer, so workers are aware of the findings.
  11. OSHA 10-Hour Construction

    OSHA issues four main types of violations. Which type carries the highest mandatory penalty and reflects intentional or knowing disregard for OSHA requirements?

    Correct — A. A willful violation is one where the employer knowingly or intentionally violated an OSHA requirement, and it carries the highest mandatory penalty per violation; a repeat violation involves re-citation for a substantially similar condition and also carries elevated penalties.
  12. OSHA 10-Hour Construction

    Which of the following scenarios would most likely be cited under the General Duty Clause rather than a specific 29 CFR 1926 standard?

    Correct — B. The General Duty Clause applies when a recognized hazard exists but no specific OSHA standard covers it; because there is currently no specific 29 CFR 1926 standard for heat illness in construction, heat stress citations are typically issued under the General Duty Clause.
  13. OSHA 10-Hour Construction

    Under OSHA's multi-employer worksite policy on construction sites, which employer bears primary citation responsibility for a hazardous condition that it created but that also exposes workers employed by a different subcontractor?

    Correct — A. Under OSHA's multi-employer citation policy, the employer who created a hazard bears primary responsibility; a controlling employer (such as a general contractor) can also be cited if it had supervisory authority over the worksite and failed to exercise reasonable care to discover and correct the violation.
  14. OSHA 10-Hour Construction

    A worker refuses to perform a task, stating there is a real danger of death or serious injury and there is not enough time to eliminate the hazard through normal OSHA complaint channels. Under OSHA's regulations, which condition is NOT required for a worker's refusal to be protected from disciplinary action?

    Correct — C. Under 29 CFR 1977.12, a worker's protected right to refuse dangerous work does not require prior written authorization from OSHA; the worker must have a good-faith belief of imminent danger, have requested correction, been refused, and have no reasonable alternative — but OSHA pre-approval is not a condition.
  15. OSHA 10-Hour Construction

    Under OSHA Construction standards, at what height above a lower level are workers generally required to be protected from falls?

    Correct — B. 29 CFR 1926.502 establishes 6 feet as the trigger height for fall protection requirements in most construction activities, making it the central threshold in the OSHA Focus Four Falls topic.
  16. OSHA 10-Hour Construction

    Which of the following is an acceptable primary form of fall protection recognized by the OSHA Construction standard?

    Correct — B. 29 CFR 1926.502 recognizes personal fall arrest systems as one of three primary fall protection methods, alongside guardrail systems and safety nets.
  17. OSHA 10-Hour Construction

    Which component of a personal fall arrest system is worn directly on the worker's body?

    Correct — C. 29 CFR 1926.502(d) requires that a full-body harness — not a body belt — serve as the body-wear element of any personal fall arrest system in construction.
  18. OSHA 10-Hour Construction

    When a portable ladder is used to reach an upper landing surface, how far must the side rails extend above that landing?

    Correct — A. 29 CFR 1926.1053(b)(1) requires ladder side rails to extend at least 3 feet above the upper landing to give workers a stable handhold when stepping on and off the ladder.
  19. OSHA 10-Hour Construction

    Under OSHA Construction standards, the anchorage point for a personal fall arrest system must be capable of supporting at least how much weight per attached employee?

    Correct — A. 29 CFR 1926.502(d)(15) requires anchorages for personal fall arrest equipment to support at least 5,000 pounds per attached employee, or be designed with a safety factor of at least two by a qualified person.
  20. OSHA 10-Hour Construction

    A worker using a personal fall arrest system must be rigged so that the maximum free-fall distance does not exceed how many feet?

    Correct — D. 29 CFR 1926.502(d)(16)(iii) limits the free-fall distance for a personal fall arrest system to no more than 6 feet, and the system must also prevent the worker from contacting a lower level.
  21. OSHA 10-Hour Construction

    What is the required top-rail height for a guardrail system installed on a construction worksite?

    Correct — C. 29 CFR 1926.502(b)(1) specifies that the top edge of a guardrail must be 42 inches (plus or minus 3 inches) above the walking-working surface.
  22. OSHA 10-Hour Construction

    Per OSHA's Construction standard, safety nets used as fall protection must be installed no more than how far below the working surface where workers may fall?

    Correct — A. 29 CFR 1926.502(c)(1) requires safety nets to be installed as close as practicable under the walking-working surface but no more than 30 feet below it.
  23. OSHA 10-Hour Construction

    At what height above a lower level does OSHA require fall protection for workers on supported scaffolds?

    Correct — D. 29 CFR 1926.451(g)(1) requires fall protection for employees on scaffolds more than 10 feet above a lower level, which is a higher threshold than the general 6-foot rule.
  24. OSHA 10-Hour Construction

    After a personal fall arrest system has arrested a worker's fall, what must happen before the equipment is used again?

    Correct — D. 29 CFR 1926.502(d)(20) requires that any personal fall arrest system subjected to impact loading during a fall be immediately removed from service until a competent person inspects it and determines it is undamaged and suitable for reuse.
  25. OSHA 10-Hour Construction

    A hole in a walking-working surface is covered with a temporary wooden cover. Under OSHA standards, that cover must be able to support at least how much weight?

    Correct — B. 29 CFR 1926.502(i)(2) requires floor-hole covers to support without failure at least twice the weight of employees, equipment, and materials that could be imposed on the cover at any one time.
  26. OSHA 10-Hour Construction

    A leading-edge employer determines that conventional fall protection (guardrails, PFAS, and safety nets) is infeasible and would create a greater hazard. What does OSHA specifically require before that employer may proceed with an alternative fall protection plan?

    Correct — D. 29 CFR 1926.502(k) permits an alternative fall protection plan for leading-edge work only when conventional methods are infeasible or create a greater hazard, and requires the plan to be written, site-specific, prepared by a qualified person, and kept at the job site.
  27. OSHA 10-Hour Construction

    Which specific combination of fall protection is OSHA required for workers on two-point adjustable suspension scaffolds?

    Correct — C. 29 CFR 1926.451(g)(3) explicitly requires workers on two-point adjustable suspension scaffolds to be protected by both a personal fall arrest system and a guardrail system due to the heightened hazard of that scaffold type.
  28. OSHA 10-Hour Construction

    Under the OSHA Construction fall protection standard, which statement correctly describes when an employer may use a safety monitoring system as the sole means of fall protection?

    Correct — C. 29 CFR 1926.502(h) and (j) limit safety monitoring systems to low-slope roof work where other protection is infeasible, and generally require them to be combined with a warning line system; the monitor may serve as sole protection only in areas too small or too close to an edge to use a warning line.
  29. OSHA 10-Hour Construction

    What is the primary purpose of a Ground-Fault Circuit Interrupter (GFCI) on a construction site?

    Correct — C. A GFCI monitors the difference between current on the hot and neutral conductors; if an imbalance of approximately 5 milliamps is detected — indicating current is flowing through a person — it trips within milliseconds, as required by 29 CFR 1926.404(b)(1).
  30. OSHA 10-Hour Construction

    Under 29 CFR 1926 Subpart K, which of the following best describes when lockout/tagout (LOTO) procedures must be applied on a construction site?

    Correct — B. 29 CFR 1926.417 requires that sources of electrical energy be de-energized and locked or tagged out before employees work on or near them to prevent unexpected energization, startup, or release of stored energy.
