200 QUESTIONS AND ANSWERS
Question 1
What is the primary purpose of NFPA 70E? Answer: To provide a practical
safe working area for employees relative to the hazards arising from the use of
electricity.
Question 2
What does an "electrically safe work condition" mean? Answer: A state in
which an electrical conductor or circuit part has been disconnected,
locked/tagged out, tested to verify the absence of voltage, and, if necessary,
temporarily grounded.
Question 3
What are the two types of electrical hazards defined in NFPA 70E? Answer:
Shock hazard and arc flash hazard.
Question 4
What is the shock protection boundary where unqualified persons may not cross
without qualified escort? Answer: Limited Approach Boundary.
Question 5
What document must be completed before work within the Limited Approach
Boundary or Arc Flash Boundary? Answer: An Energized Electrical Work
Permit (unless exemptions apply).
,Question 6
What is the purpose of an arc flash risk assessment? Answer: To identify arc
flash hazards, estimate the likelihood of occurrence and potential severity of
injury, and determine if additional protective measures are required.
Question 7
Which of the following is NOT one of the approach boundaries for shock
protection? Answer: Flash Protection Boundary (the three shock protection
boundaries are Limited Approach, Restricted Approach, and Prohibited
Approach).
Question 8
At what voltage level does NFPA 70E consider equipment to be "high voltage"?
Answer: Over 1000 volts.
Question 9
What does PPE stand for in electrical safety? Answer: Personal Protective
Equipment.
Question 10
Which of the following is NOT a justified condition for working on energized
equipment according to NFPA 70E? Answer: To save time or money on a
project.
Question 11
How often must employees who face a risk of electrical hazard receive
electrical safety training? Answer: At intervals not to exceed 3 years.
Question 12
What is the minimum arc rating for protective clothing when working on
equipment with an incident energy of 10 cal/cm²? Answer: Greater than 10
cal/cm² (typically would require PPE Category 3 or higher).
Question 13
Which of the following is NOT a typical component of host and contract
employer responsibilities? Answer: The host employer is solely responsible for
, all electrical accidents (incorrect - responsibilities are shared and defined for
both parties).
Question 14
What is an "arc flash boundary"? Answer: The distance from a prospective arc
source within which a person could receive a second-degree burn if an electrical
arc flash were to occur.
Question 15
What method must be used to verify that a circuit is de-energized before work
begins? Answer: Testing the circuit with an adequately rated test instrument.
Would you like more questions, or would you like me to focus on a specific
aspect of NFPA 70E?
Question 16
What is an "incident energy analysis"? Answer: A component of an arc flash
risk assessment that determines the incident energy exposure of the worker for
specific equipment.
Question 17
What does LOTO stand for in electrical safety procedures? Answer:
Lockout/Tagout.
Question 18
Which NFPA 70E category requires a minimum arc rating of 25 cal/cm²?
Answer: PPE Category 4.
Question 19
Under NFPA 70E, electrical equipment operating at 50 volts or more must be:
Answer: De-energized before work is performed, unless de-energizing
introduces additional hazards or is infeasible.
Question 20
The ________ Approach Boundary is the distance within which only qualified
persons may work. Answer: Restricted.
