C. Provide retirement benefits
D. Furnish employment and a place of employment free from recognized hazards
causing or likely to cause death or serious physical harm

illnesses (OSHA 300 Log) if the company has more than how many employees?
A. 10 employees
B. 5 employees
C. 50 employees

Question 4. The OSHA standard that governs construction safety and health is found in
which Code of Federal Regulations (CFR)?
A. 29 CFR 1910
B. 29 CFR 1926
C. 29 CFR 1904
D. 40 CFR 260
✓ Correct Answer: B
Rationale: 29 CFR 1926 covers construction industry safety and health regulations. 29 CFR 1910
covers general industry standards. Construction workers are governed by Part 1926.
Question 5. OSHA's 'multi-employer worksite doctrine' holds that:
A. Multiple employers on a worksite can be cited for hazards—including creating,
exposing, correcting, or controlling employers
B. Only the property owner is liable
C. Only the general contractor is responsible for safety
D. Employees are solely responsible for their own safety
✓ Correct Answer: A
Rationale: The multi-employer doctrine identifies four types of responsible employers: creating
(created the hazard), exposing (employees exposed to hazard), correcting (responsible for
correcting), and controlling (general control over worksite safety).
Question 6. An OSHA 'willful' violation is one in which the employer:
A. Has never been inspected before
B. Complies with most but not all standards
C. Intentionally and knowingly commits a violation or is indifferent to the law

A. A minor paperwork error exists
B. There is substantial probability that death or serious physical harm could
result from a condition
C. No injuries have occurred yet

Rationale: A serious violation exists when there is substantial probability that death or serious
physical harm could result and the employer knew or should have known of the hazard. Penalties
can reach $16,131 per violation (2024).
Question 9. OSHA requires that Safety Data Sheets (SDS) be:
A. Readily accessible to employees during each work shift for all hazardous
chemicals

C. Provided only upon written request
D. Kept locked in the supervisor's office
