1. A Texas industrial facility is updating its safety management
system to reduce workplace injuries. Which action best
demonstrates the hierarchy of controls by applying the most
effective hazard control?
A. Requiring all workers to wear safety glasses
B. Posting warning signs around the hazard
C. Replacing a toxic solvent with a less hazardous product
D. Conducting monthly safety meetings
Answer: C. Replacing a toxic solvent with a less hazardous product
Rationale: The hierarchy of controls ranks hazard elimination and
substitution as the most effective methods. Substituting a hazardous
chemical with a less hazardous one removes or significantly reduces risk
at its source. PPE and administrative controls are less effective because
they rely heavily on worker compliance.
2. An employee enters a confined space without testing the
atmosphere. Which atmospheric hazard presents the greatest
immediate threat to life?
A. 20.9% oxygen
B. 18% oxygen with elevated carbon monoxide
C. Normal humidity
D. Low noise levels
1
,Answer: B. 18% oxygen with elevated carbon monoxide
Rationale: An oxygen concentration below 19.5% is considered oxygen-
deficient and immediately dangerous, especially when combined with
toxic gases such as carbon monoxide. Atmospheric testing must always
precede confined space entry.
3. Which OSHA recordkeeping requirement determines whether an
injury must be recorded on the OSHA 300 Log?
A. Employee age
B. Supervisor recommendation
C. Medical treatment beyond first aid
D. Employee job classification
Answer: C. Medical treatment beyond first aid
Rationale: Recordable injuries include those involving death, days away
from work, restricted duty, loss of consciousness, or medical treatment
beyond first aid.
4. During a Job Hazard Analysis (JHA), what should be completed
immediately after identifying each task step?
A. Estimate company profits
B. Identify hazards associated with that step
C. Assign overtime
D. Purchase PPE
Answer: B. Identify hazards associated with that step
Rationale: A JHA systematically identifies individual job steps,
associated hazards, and appropriate controls before work begins.
5. A forklift operator is transporting a heavy load uphill. What is the
safest operating practice?
A. Drive with the load facing uphill
B. Reverse uphill
2
,C. Raise the forks high
D. Turn sharply while climbing
Answer: A. Drive with the load facing uphill
Rationale: When carrying a load on an incline, the load should remain
uphill to prevent tipping. Keeping the load low enhances stability.
6. What is the primary purpose of Lockout/Tagout (LOTO)?
A. Increase production
B. Prevent unexpected energization of equipment
C. Reduce utility costs
D. Improve maintenance scheduling
Answer: B. Prevent unexpected energization of equipment
Rationale: LOTO protects workers from hazardous energy by ensuring
equipment cannot start unexpectedly during servicing.
7. A combustible dust accumulation is discovered near processing
equipment. What should be the technician's first action?
A. Blow the dust into the air
B. Continue operations
C. Remove ignition sources and clean using approved methods
D. Wet the dust with gasoline
Answer: C. Remove ignition sources and clean using approved
methods
Rationale: Combustible dust explosions require fuel, oxygen,
confinement, dispersion, and ignition. Eliminating ignition sources and
using explosion-safe cleaning methods minimizes risk.
8. Which fire extinguisher should be used on energized electrical
equipment?
3
, A. Class A
B. Class B
C. Class C
D. Class K
Answer: C. Class C
Rationale: Class C extinguishers contain nonconductive agents
appropriate for energized electrical fires.
9. Noise monitoring indicates employees are exposed to 92 dBA over
an eight-hour TWA. What OSHA requirement applies?
A. No action needed
B. Implement a Hearing Conservation Program
C. Replace all equipment immediately
D. Shut down operations permanently
Answer: B. Implement a Hearing Conservation Program
Rationale: An 8-hour TWA of 85 dBA triggers OSHA's Hearing
Conservation Program, while 90 dBA is the permissible exposure limit.
10. Which gas detector should be used first before entering a
confined space?
A. Radiation detector
B. Oxygen monitor
C. Vibration analyzer
D. Lux meter
Answer: B. Oxygen monitor
Rationale: Oxygen concentration should always be measured first
because sensor performance for other gases depends on adequate
oxygen levels.
11. What is the primary objective of a safety audit?
