• C) To regulate workers' compensation payouts for workplace
injuries
• D) To mandate annual safety training for all corporate executives
Correct Answer: B
Rationale: The General Duty Clause requires employers to maintain a
safe and healthful workplace, specifically addressing serious hazards
where no specific OSHA standard applies.
Question 2: According to the hierarchy of hazard controls, which control
method is considered the most effective?
• A) Personal Protective Equipment (PPE)
• B) Administrative controls
• C) Engineering controls
• D) Elimination
,Correct Answer: D
Rationale: Elimination physically removes the hazard entirely from the
workplace, making it the most effective control method in the hierarchy.
Question 3: Under the Globally Harmonized System (GHS) for Hazard
Communication, how many standard sections are required on a Safety
Data Sheet (SDS)?
• A) 8 sections
• B) 12 sections
• C) 16 sections
• D) 20 sections
Correct Answer: C
Rationale: GHS-compliant Safety Data Sheets universally follow a strict
16-section format for consistency in hazard communication globally.
Question 4: What is the primary objective of a Job Safety Analysis (JSA)
or Job Hazard Analysis (JHA)?
• A) To discipline employees who violate safety rules
• B) To break down a specific job into steps to identify hazards and
determine hazard controls
• C) To calculate annual workers' compensation insurance premiums
• D) To design corporate office layouts and workstations
Correct Answer: B
,Rationale: A JSA systematically examines job tasks step-by-step to
uncover potential hazards and implement corresponding safety
controls.
Question 5: Under OSHA standards, what is the general trigger height
for mandatory fall protection in construction environments?
• A) 4 feet
• B) 6 feet
• C) 10 feet
• D) 15 feet

• A) Lift Operations and Transport Oversight
• B) Lockout / Tagout
• C) Local Occupational Testing Organization
• D) Lifeline Observation and Tethering Operation
Correct Answer: B
Rationale: LOTO refers to Lockout/Tagout procedures used to safeguard
workers from hazardous energy sources during equipment servicing and
maintenance.
Question 8: At what continuous noise exposure level (8-hour TWA) does
OSHA require employers to implement a Hearing Conservation
Program?
• A) 80 decibels (dBA)
• B) 85 decibels (dBA)
• C) 90 decibels (dBA)
• D) 100 decibels (dBA)
Correct Answer: B
Rationale: An 8-hour time-weighted average (TWA) of 85 dBA is the
action level that triggers mandatory hearing conservation measures.
Question 9: Which component is NOT one of the four core phases of
industrial hygiene practice?
• A) Anticipation
