When performing dielectric withstand testing, what additional safety precaution is critical beyond standard PPE?
Answer: Establishing a clear safety perimeter and warning barrier around the test area
A clearly marked safety perimeter prevents unqualified personnel from entering the test zone where lethal voltages are applied.
What does an ATPV (Arc Thermal Performance Value) rating on arc-rated clothing indicate?
Answer: The incident energy level at which the garment has a 50% probability of preventing a second-degree burn
ATPV represents the incident energy (cal/cm²) at which there is a 50% probability that the fabric prevents onset of a second-degree burn.
Which type of safety sign color indicates an immediate danger that will result in death or serious injury if not avoided?
Answer: Red
Red is used for DANGER signs per ANSI Z535.2, indicating an imminently hazardous situation that will result in death or serious injury.
A NETA technician is testing a transformer with residual charge. Before disconnecting test leads, what must be done?
Answer: Discharge the transformer through a grounding stick or discharge resistor
Capacitive and inductive energy stored in transformers must be discharged through a grounding stick or discharge resistor before lead removal to prevent shock.
What is the correct response if a co-worker receives an electrical shock and cannot release the energized conductor?
Answer: De-energize the circuit immediately or use a non-conductive object to separate them
The rescuer must de-energize the circuit first or use a non-conductive object to separate the victim without becoming a second victim.
Which OSHA standard specifically addresses the electrical safety requirements for general industry workplaces?
Answer: OSHA 29 CFR 1910 Subpart S
OSHA 29 CFR 1910 Subpart S covers electrical safety standards for general industry, including design and safety requirements.
What is the minimum approach distance for unqualified persons near exposed energized parts at 15 kV phase-to-ground?
Answer: 10 feet (3.05 m)
OSHA 1910.333 and NFPA 70E Table 130.4(D)(a) require unqualified persons to maintain at least 10 feet from exposed energized parts at distribution voltages.
