1. What is the primary purpose of NFPA 70E?
A. Establish electrical installation requirements
B. Establish workplace electrical safety requirements
C. Regulate utility power generation
D. Establish OSHA penalties
Answer: B. Establish workplace electrical safety requirements
Rationale: NFPA 70E provides requirements for electrical safety-related
work practices to protect employees from electrical hazards such as
shock, arc flash, and arc blast. Unlike the NEC (NFPA 70), which governs
installations, NFPA 70E focuses on safe work practices.
2. Which organization publishes NFPA 70E?
A. OSHA
B. IEEE
C. NFPA
D. ANSI
,Rationale: The National Fire Protection Association (NFPA) develops and
publishes NFPA 70E through a consensus standards process involving
industry experts.
3. Which hazard is most commonly associated with electrical work?
A. Chemical burns only
B. Falling objects
C. Electric shock and arc flash
D. Radiation exposure
Rationale: Electrical workers are primarily exposed to electric shock, arc
flash, and arc blast hazards. These hazards can result in severe burns,
cardiac arrest, blindness, hearing damage, or death.
4. Which federal agency enforces workplace electrical safety
regulations in the United States?
A. EPA
B. FEMA
C. OSHA
D. DOT
Rationale: OSHA enforces workplace safety regulations and frequently
references NFPA 70E as a recognized industry standard for complying
with electrical safety requirements.
5. Before an employee begins electrical work, the employer must
establish:
, A. Marketing policies
B. Payroll procedures
C. An electrical safety program
D. Equipment warranties
Rationale: NFPA 70E requires employers to implement and maintain an
electrical safety program that includes procedures, training, hazard
identification, and continuous improvement.
6. Which condition is considered electrically safe?
A. Circuit breaker is open
B. Equipment is unplugged
C. An electrically safe work condition has been established
following NFPA 70E procedures
D. Voltage tester is nearby
Rationale: An electrically safe work condition requires identifying power
sources, interrupting load current, opening disconnects, applying
lockout/tagout, verifying absence of voltage, and grounding where
necessary.
7. What is the first priority when performing electrical work?
A. Completing the task quickly
B. Minimizing downtime
C. Protecting employees from injury
D. Saving energy
Rationale: The purpose of NFPA 70E is to prevent injuries and fatalities
through proper planning, hazard elimination, and safe work practices.
, 8. What is an arc flash?
A. A lightning strike
B. A voltage drop
C. A dangerous release of energy caused by an electrical fault
through air
D. A grounding method
Rationale: Arc flash occurs when electric current leaves its intended
path and travels through the air, producing intense heat, pressure,
molten metal, and ultraviolet radiation.
9. Which hazard can accompany an arc flash?
A. Frostbite
B. Carbon monoxide
C. Arc blast
D. Mold growth
Rationale: Arc blast is the pressure wave produced during an arc flash. It
can propel debris, damage hearing, and throw workers across rooms.
10. What is the preferred method of protecting workers from
electrical hazards?
A. PPE only
B. Warning signs
C. Administrative controls
D. Elimination of the hazard
