Q1Under the OSH Act, which of the following is a general duty that every covered employer must fulfill?
Show answer
✓ Correct answer: Provide a workplace free from recognized hazards likely to cause death or serious physical harm
Section 5(a)(1) of the OSH Act — the General Duty Clause — requires every employer to furnish a place of employment free from recognized hazards that are causing or are likely to cause death or serious physical harm to employees.
Q2Which OSHA recordkeeping form is used to summarize the total number of job-related injuries and illnesses for a calendar year and must be posted in the workplace from February 1 through April 30?
Show answer
✓ Correct answer: OSHA Form 300A
OSHA Form 300A is the Summary of Work-Related Injuries and Illnesses; 29 CFR 1904.32 requires employers to post it in a conspicuous place from February 1 through April 30 of the year following the period covered.
Q3A worker believes his employer has created a serious safety hazard on the job site. Under the OSH Act, what right does that worker have?
Show answer
✓ Correct answer: The right to file a complaint with OSHA without fear of retaliation or discrimination
Section 11(c) of the OSH Act protects workers who exercise their rights — including filing a safety complaint — from retaliation or discrimination by their employer.
Q4During an OSHA programmed inspection of a construction site, the compliance officer asks to see the employer's OSHA injury and illness logs. The employer must provide those records within:
Show answer
✓ Correct answer: 4 business hours
Under 29 CFR 1904.40, when an OSHA representative requests records, the employer must provide copies of the OSHA 300, 300A, and 301 forms by the end of the next business day — commonly interpreted as within 4 business hours during an on-site inspection.
Q5A supervisor discovers that a subcontractor on a multi-employer worksite has created an electrical hazard that could expose employees of other trades to harm. Under OSHA's multi-employer worksite policy, which party can OSHA cite for that hazard?
Show answer
✓ Correct answer: The creating employer, and potentially the controlling and exposing employers
OSHA's multi-employer citation policy allows the agency to cite the creating, exposing, correcting, and/or controlling employer depending on each party's role and knowledge of the hazard.
Q6After receiving an OSHA citation, an employer who disagrees with the finding must contest it within how many working days of receiving the citation?
Show answer
✓ Correct answer: 15 working days
Under Section 10(a) of the OSH Act, an employer must notify OSHA in writing of its intent to contest a citation within 15 working days of receipt; failure to contest makes the citation a final order not subject to review.
Q7Which of the following best describes the role of a 'competent person' as defined throughout OSHA construction standards?
Show answer
✓ Correct answer: One who is capable of identifying existing and predictable hazards and who has authority to take prompt corrective action
29 CFR 1926.32(f) defines a competent person as one who is capable of identifying existing and predictable hazardous conditions and who has authority to take prompt corrective measures to eliminate them.
Q8OSHA Form 301, the Injury and Illness Incident Report, must be completed within how many calendar days of a recordable work-related injury or illness?
Show answer
✓ Correct answer: 7 calendar days
29 CFR 1904.29(b)(3) requires that each OSHA Form 301 (or equivalent) be completed within 7 calendar days of receiving information that a recordable case occurred.
Q9When OSHA conducts an unprogrammed inspection triggered by a worker fatality, which inspection priority category does this fall under?
Show answer
✓ Correct answer: Imminent danger / catastrophe and fatal accident
OSHA's inspection priority order places imminent-danger situations and fatality/catastrophe investigations at the top, ahead of complaints, referrals, and programmed planned inspections.
Q10An employer receives an OSHA citation classified as 'willful' with a proposed penalty. Which statement correctly describes a willful violation?
Show answer
✓ Correct answer: The employer intentionally and knowingly committed the violation or was aware a hazardous condition existed and made no reasonable effort to eliminate it
OSHA defines a willful violation as one committed with plain indifference to, or intentional disregard of, employee safety and health requirements — distinct from repeat violations, which involve a prior citation history.
