1. What is the primary purpose of a Job Hazard Analysis (JHA)?
A) Train employees in company policies
B) Identify hazards and implement controls before work begins
C) Document OSHA inspections
D) Evaluate worker performance
Rationale: 👀*** JHAs proactively prevent accidents by assessing hazards
before tasks are performed.
2. Which hierarchy of controls is considered the most effective?
A) Personal protective equipment (PPE)
B) Administrative controls
C) Elimination/Substitution
D) Engineering controls
Rationale: 👀*** Removing the hazard or replacing it with a safer alternative is
most effective.
3. What is the OSHA permissible exposure limit (PEL) for airborne
respirable dust?
A) 1 mg/m³
B) 5 mg/m³
C) 10 mg/m³
D) 50 mg/m³
,Rationale: 👀*** OSHA sets 5 mg/m³ as the PEL for respirable dust in general
industry.
4. Which of the following is an example of an engineering control?
A) Safety training
B) Guarding a machine with a barrier
C) Using PPE
D) Job rotation
Rationale: 👀*** Engineering controls physically isolate people from hazards.
5. What is the purpose of a Safety Data Sheet (SDS)?
A) Provide company policies
B) Provide hazard information and handling instructions for chemicals
C) Record workplace accidents
D) Track employee training
Rationale: 👀*** SDSs communicate chemical hazards and safe handling
procedures.
6. Which OSHA standard applies to fall protection in general industry?
A) 29 CFR 1926
B) 29 CFR 1910 Subpart D
C) 29 CFR 1915
D) 29 CFR 1928
Rationale: 👀*** This subpart covers walking-working surfaces, including fall
protection.
,7. Which type of PPE protects against chemical splashes to the eyes?
A) Hard hat
B) Safety shoes
C) Chemical splash goggles
D) Earplugs
Rationale: 👀*** Goggles provide a tight seal to prevent chemical exposure to
the eyes.
8. What is the primary goal of incident investigation?
A) Punish employees
B) Identify root causes and prevent recurrence

D) Train employees
Rationale: 👀*** Focus is on system improvement, not blame.
9. What is a “near miss”?
A) An injury requiring medical attention
B) An event that could have caused injury or damage but did not
C) A minor safety violation
D) A failed inspection
Rationale: 👀*** Near misses are key indicators for proactive hazard control.
10. Which of the following is an administrative control?
, A) Machine guarding
B) Job rotation
C) Ventilation system
D) Substitution of a less hazardous chemical
Rationale: 👀*** Administrative controls change how people work to reduce
exposure.
11. What is the primary hazard in confined space entry?
A) Noise
B) Atmospheric hazards (oxygen deficiency, toxic gases)
C) Electrical shock
D) Ergonomic strain
Rationale: 👀*** Oxygen-deficient or toxic atmospheres are the most critical
risks in confined spaces.
12. Which method is used to determine the severity and probability of a
hazard?
A) Training
B) Risk assessment
C) PPE selection
D) Safety audit
Rationale: 👀*** Risk assessment quantifies hazard severity and likelihood to
prioritize controls.
13. Which of the following is part of a Lockout/Tagout (LOTO) procedure?
