Which safety practice is required when working in a confined space with potential electrical hazards?
Answer: Obtain a confined space entry permit and test the atmosphere before entry
Permit-required confined spaces demand an entry permit, atmospheric testing, and an attendant stationed outside before any entry.
When must an employer provide an incident energy analysis for electrical work tasks?
Answer: When the task is not covered by the NFPA 70E PPE category tables or when greater precision is needed
An incident energy analysis is required when the PPE category method doesn't apply or when engineering accuracy is needed for specific equipment.
What does 'safety by design' mean in electrical risk management?
Answer: Eliminating or minimizing hazards through equipment design and engineering controls before relying on PPE
Safety by design applies the hierarchy of controls—elimination first, then substitution and engineering controls—before administrative controls or PPE.
Which NFPA 70E article specifically addresses the requirements for establishing an electrically safe work condition?
Answer: Article 120
NFPA 70E Article 120 outlines the six-step process for establishing and verifying an electrically safe work condition.
A worker accidentally contacts a 120V energized conductor and cannot let go. What is the correct first response?
Answer: De-energize the circuit immediately using the nearest disconnect or breaker
The priority is removing the energy source immediately; touching the victim without de-energizing risks a second electrocution.
Under NFPA 70E, 'qualified person' status requires which of the following?
Answer: Training on electrical hazards and skills to distinguish exposed live parts and their voltages
A qualified person must be trained to recognize hazards, understand voltage levels, and work safely near exposed energized parts per NFPA 70E definitions.
What is the primary purpose of arc-rated (AR) clothing in electrical work?
Answer: To limit burn injury by resisting ignition and not breaking open when exposed to an arc flash
AR clothing is designed to self-extinguish and not break open in an arc flash, limiting burn severity to survivable levels.
