1. The primary purpose of NFPA 70E is to:
A. Set building codes for electrical installations
B. Provide electrical safety requirements for employees
C. Regulate utility company practices
D. Specify electrical material standards
Explanation: NFPA 70E focuses on protecting employees from electrical hazards in
the workplace.
2. An arc flash hazard can cause:
A. Minor discomfort
B. Severe burns, blindness, and fatal injuries
C. Only electrical shocks
D. Minimal injury with proper gloves
Explanation: Arc flash incidents release tremendous energy capable of causing
serious injuries.
3. The approach boundary for a shock hazard is determined by:
A. Voltage only
B. Distance from the panel
C. Voltage and available fault current
D. Type of circuit breaker
Explanation: Approach boundaries protect personnel from shock based on system
voltage and fault current.
4. What is the minimum PPE required for working on energized parts >50V?
A. Safety glasses only
B. Gloves only
, C. Shock-rated gloves, face shield, and flame-resistant clothing
D. Hard hat only
Explanation: NFPA 70E mandates PPE based on voltage, task, and potential arc
flash risk.
5. Lockout/Tagout procedures are required:
A. Only for high-voltage equipment
B. Only during maintenance outside business hours
C. Whenever equipment is serviced or maintained
D. Only for 480V circuits and above
Explanation: LOTO ensures machinery or electrical equipment cannot be energized
while work is performed.
6. The flash protection boundary is:
A. The distance from an energized source where PPE is required to prevent
injury from arc flash
B. The boundary for chemical hazards
C. A mechanical safety zone
D. The area for low-voltage circuits only
Explanation: This boundary defines the safe distance for personnel based on
potential arc flash energy.
7. Which type of glove is required for live 600V circuits?
A. Leather gloves
B. Fabric gloves
C. Class 2 rubber insulating gloves
D. Cotton gloves
Explanation: Rubber insulating gloves are classified by voltage rating for worker
protection.
8. The term “limited approach boundary” refers to:
A. The safe zone for unauthorized personnel
B. The distance where qualified personnel can approach energized parts
, with proper PPE
C. Distance to avoid chemical exposure
D. Distance from mechanical hazards
Explanation: NFPA 70E defines limited, restricted, and prohibited approach
boundaries.
9. How often should electrical PPE be inspected?
A. Once a year
B. Before each use and periodically
C. Only when visibly damaged
D. Every 5 years
Explanation: PPE must be visually inspected before use and tested periodically for
safety compliance.
10.Arc-rated clothing is required when:
A. Only working on DC circuits
B. Only for circuits below 120V
C. Working within the flash protection boundary
D. When working outdoors
Explanation: Arc-rated clothing protects against thermal energy from arc flash
events.
11.The term “qualified person” means:
A. Any employee near electrical equipment
B. A person trained and knowledgeable in electrical hazards and
procedures
C. Supervisors only
D. Anyone with 6 months of experience
Explanation: NFPA 70E defines a qualified person as one trained to recognize
hazards and reduce risks.
12.Grounding of electrical systems helps:
A. Reduce noise
