1. An employee is preparing to service a motor control panel. What is the most important first
step before beginning work?
A. Test the motor under load
B. Notify production staff only
C. Establish an electrically safe work condition
D. Remove warning labels
════════════════════
Correct Answer: C. Establish an electrically safe work condition
Rationale:
Establishing an electrically safe work condition through proper lockout/tagout procedures is
the primary method of protecting workers from electrical hazards. The other options do not
adequately control electrical risks.
════════════════════
2. Which hazard is most commonly associated with accidental contact with energized
conductors?
A. Electric shock
B. Noise exposure
C. Repetitive strain injury
D. Heat stress
════════════════════
Correct Answer: A. Electric shock
Rationale:
Electric shock occurs when current passes through the body. While other workplace hazards
exist, accidental contact with energized conductors most directly creates a shock hazard.
════════════════════
,3. What does OSHA require before an employee performs electrical work on equipment that
has been de-energized?
A. Verbal confirmation only
B. Voltage verification
C. Removal of all PPE
D. Supervisor observation only
════════════════════
Correct Answer: B. Voltage verification
Rationale:
Workers must verify the absence of voltage using properly rated test equipment. Assuming
equipment is de-energized without testing can result in serious injury.
════════════════════
4. Which item is considered electrical personal protective equipment (PPE)?
A. Hard hat sticker
B. Safety clipboard
C. Cotton apron
D. Arc-rated gloves
════════════════════
Correct Answer: D. Arc-rated gloves
Rationale:
Arc-rated gloves help protect workers from electrical and thermal hazards. The other items do
not provide equivalent electrical protection.
════════════════════
5. A worker notices damaged insulation on an extension cord. What should be done?
A. Continue using it temporarily
B. Repair it with tape and continue
C. Remove it from service
,D. Use it only outdoors
════════════════════
Correct Answer: C. Remove it from service
Rationale:
Damaged insulation creates a shock and fire hazard. The safest action is to remove the cord
from service until properly repaired or replaced.
════════════════════
6. What is the primary purpose of lockout/tagout procedures?
A. Increase productivity
B. Prevent unexpected energization
C. Reduce paperwork
D. Improve equipment efficiency
════════════════════
Correct Answer: B. Prevent unexpected energization
Rationale:
Lockout/tagout controls hazardous energy and prevents equipment from unexpectedly
starting or becoming energized during servicing.
════════════════════
7. Which employee is generally permitted to work on exposed energized electrical parts?
A. Any trained employee
B. New employee under observation
C. Qualified person
D. Administrative employee
════════════════════
Correct Answer: C. Qualified person
Rationale:
, A qualified person possesses the skills and knowledge necessary to recognize and avoid
electrical hazards.
════════════════════
8. Why are warning labels placed on electrical equipment?
A. Decoration
B. Inventory tracking
C. Marketing purposes
D. Hazard communication
════════════════════
Correct Answer: D. Hazard communication
Rationale:
Warning labels provide critical information about potential electrical hazards and necessary
protective measures.
════════════════════
9. Which action best reduces the risk of arc flash injury?
A. Wearing arc-rated PPE
B. Standing on cardboard
C. Removing gloves
D. Turning off room lights
════════════════════
Correct Answer: A. Wearing arc-rated PPE
Rationale:
Arc-rated PPE helps protect workers from thermal energy released during an arc flash event.
════════════════════
10. What should be checked before using a voltage tester?
A. Paint color
