Q1: Under the OSH Act, an employer must report a fatality to OSHA within what timeframe?
A. 4 hours
B. 8 hours
C. 24 hours
D. 48 hours

OSHA within 8 hours of the employer's knowledge of the incident. Hospitalizations,
amputations, and loss of an eye must be reported within 24 hours. Option C refers to the
reporting time for inpatient hospitalization, amputation, or loss of an eye, not fatalities.
Q2: Which section of the OSH Act contains the "General Duty Clause," requiring employers to
provide a workplace free from recognized hazards?
A. Section 4
B. Section 5(a)(1)
C. Section 8(c)

cause death or serious physical harm. Section 11(c) covers whistleblower protections, and
Section 8 pertains to inspections and citations.
Q3: What is the correct order of priority for OSHA inspections?
A. Imminent danger, complaints/referrals, catastrophes/fatalities, planned inspections, follow-
ups.
B. Planned inspections, imminent danger, complaints, follow-ups.
C. Imminent danger, catastrophes/fatalities, complaints/referrals, planned inspections, follow-
ups.
D. Complaints/referrals, imminent danger, planned inspections.
Correct Answer: C

catastrophes (hospitalizations of 3 or more employees); 3) Employee complaints/referrals; 4)
Targeted inspections (high-hazard industries); 5) Follow-up inspections. Imminent danger is
always the top priority to prevent loss of life.
Q4: An employee is exposed to a hazardous chemical that causes permanent lung damage, but no
days away from work are recorded. Is this recordable on the OSHA 300 Log?
A. No, because there were no days away from work.
B. Yes, because it involves a needlestick.
C. No, unless the employee requires medical treatment beyond first aid.
D. Yes, because it meets the criteria for a significant injury or illness (diagnostic of a significant
health condition).
Correct Answer: D
Rationale: Under OSHA Recordkeeping Standard 1904.7, an injury or illness is recordable if it
results in death, days away from work, restricted work, job transfer, medical treatment beyond
first aid, loss of consciousness, OR a diagnosis of a significant injury/illness (such as cancer,
chronic irreversible disease, fractured or cracked bone). Permanent lung damage is a significant

view trade secrets that are not relevant to their health.
