Complete Study Solution | Questions,
Answers & Rationale | 2026/2027.
DOMAIN 1: Introduction to OSHA, Inspections & the General Duty Clause (10 Questions)
Question 1 (Multiple-Choice)
A construction superintendent notices that workers are exposed to unguarded rebar
protruding from a concrete slab at ankle height, creating a serious impalement hazard. The
superintendent has not addressed the hazard despite receiving complaints. Under which
specific provision of the OSH Act is the employer most directly in violation?
A. Section 8(a) — Inspection Authority
B. Section 5(a)(1) — The General Duty Clause
C. Section 11(c) — Whistleblower Protection
D. Section 6(b) — National Consensus Standards
Answer: B [CORRECT]
Rationale: Section 5(a)(1) of the OSH Act, known as the "General Duty Clause," mandates that
each employer "shall furnish to each of his employees employment and a place of employment
which are free from recognized hazards that are causing or are likely to cause death or serious
physical harm." Unguarded rebar is a universally recognized impalement hazard in construction.
The employer's failure to address a hazard that is well-known in the industry and likely to cause
serious physical harm constitutes a direct violation of the General Duty Clause.
Question 2 (True/False)
True or False: Under the General Duty Clause, an employer can be cited even if no specific
OSHA standard exists for the hazard, provided the hazard is recognized in the industry and is
likely to cause death or serious physical harm.
, 2
A. True
B. False
Answer: A [CORRECT]
Rationale: This is the fundamental purpose of the General Duty Clause (OSH Act Section
5(a)(1)). OSHA can issue citations when: (1) a hazard exists; (2) the hazard is recognized (by the
employer or the industry); (3) the hazard is causing or is likely to cause death or serious physical
harm; and (4) a feasible abatement method exists. This provision fills regulatory gaps where no
specific 29 CFR 1926 standard directly addresses the hazard.
Question 3 (Multiple-Choice)
A roofing contractor is cited by OSHA for failing to provide fall protection at a height of 5 feet
on a residential roof. The contractor argues that no specific OSHA standard applies because
the work is residential. Under the General Duty Clause, what is OSHA's most likely position?
A. The General Duty Clause does not apply to residential construction
B. The General Duty Clause applies because falls from any height are recognized hazards
C. The General Duty Clause applies because falls from elevated surfaces are a recognized hazard
likely to cause death or serious physical harm, and feasible abatement exists
D. The General Duty Clause only applies when an OSHA standard specifically references
residential work
Answer: C [CORRECT]
Rationale: The General Duty Clause (OSH Act Section 5(a)(1)) applies universally to all
employers regardless of industry type or project classification. Falls from elevated surfaces are
one of the most recognized hazards in construction (the "Fatal Four"). OSHA has established
through industry consensus, NIOSH research, and incident data that falls from elevated surfaces
are likely to cause death or serious physical harm. Feasible abatement methods (guardrails,
PFAS, safety nets) are readily available, making a General Duty Clause citation appropriate.
Question 4 (Multiple-Choice)
, 3
A carpenter on a commercial construction site believes that the scaffolding is improperly
erected and poses a collapse risk. The carpenter wants to file a complaint with OSHA but fears
termination. Which specific right under the OSH Act protects this worker from retaliation?
A. Section 11(c) — Whistleblower Protection
B. Section 8(f) — Variance Request
C. Section 6(b) — Temporary Emergency Standard
D. Section 5(a)(2) — Employer Compliance with Standards
Answer: A [CORRECT]
Rationale: Section 11(c) of the OSH Act specifically prohibits employers from retaliating against
workers who exercise their rights under the Act, including the right to file a complaint with
OSHA, participate in an OSHA inspection, or testify in any proceeding under the Act. Retaliation
includes discharge, demotion, transfer, reduction in pay, or any other form of discrimination.
Workers who believe they have been retaliated against must file a complaint with OSHA within
30 days of the alleged retaliatory action.
Question 5 (True/False)
True or False: Under the OSH Act, a worker has the right to request and receive a copy of their
personal medical monitoring records, including exposure monitoring results for silica, lead, or
asbestos, at no cost and within a reasonable time.
A. True
B. False
Answer: A [CORRECT]
Rationale: The OSH Act, specifically 29 CFR 1910.1020 (Access to Employee Exposure and
Medical Records), grants workers the right to access their personal exposure and medical
records. Employers must preserve these records for the duration of employment plus 30 years
(for exposure records) or the duration of employment plus 30 years (for medical records).
Workers have the right to request copies at no cost, and employers must provide access within
15 working days of the request. This right is fundamental to worker empowerment and health
surveillance.

Question 6 (Select-All-That-Apply)
Which of the following are specific worker rights guaranteed under the OSH Act? (Select all
that apply)
A. The right to request an OSHA inspection without fear of retaliation
B. The right to receive training on hazardous chemicals in a language the worker understands
C. The right to access personal medical and exposure monitoring records
D. The right to refuse work that poses an imminent danger, under specific conditions
E. The right to a workplace free from all workplace injuries
Answer: A, B, C, D [CORRECT]
Rationale: The OSH Act guarantees workers the right to request an OSHA inspection (Section
8(f)) without retaliation (Section 11(c)). Under the Hazard Communication Standard (29 CFR
1926.59), workers have the right to training in a language they understand. Under 29 CFR
1910.1020, workers have the right to access their personal medical and exposure records.
Workers also have the limited right to refuse work under the "imminent danger" provision when
there is reasonable apprehension of death or serious injury, the employer refuses to correct the
hazard, and the hazard is so immediate that there is insufficient time for OSHA inspection.
Option E is incorrect because the OSH Act does not guarantee a workplace free from all injuries
— it mandates a workplace free from recognized hazards likely to cause death or serious
physical harm.
Question 7 (Multiple-Choice)
OSHA issues a citation to a general contractor for a "Willful" violation after discovering that
the contractor knowingly removed guardrails from a sixth-floor leading edge to speed up
material delivery, despite previous OSHA training on fall protection requirements. What is the
maximum civil penalty OSHA can assess for this willful violation (as of 2026)?
A. $7,000 per violation
B. $15,625 per violation
C. $145,027 per violation
D. $156,259 per violation
Answer: D [CORRECT]
