Which condition would require an immediate work stoppage and evacuation of the electrical work area?
Answer: Smoke, burning smell, or arcing sounds from energized equipment
Smoke, burning odors, or arcing indicate an active electrical fault or fire condition requiring immediate evacuation and notification of emergency services.
How often must rubber insulating gloves be electrically tested per ASTM standards?
Answer: Every 6 months
ASTM F496 requires rubber insulating gloves to be electrically tested every 6 months, with a visual and air inflation inspection performed before each use.
When a worker is assigned to a 'hot work' zone involving electrical equipment, which document should be reviewed to understand the specific arc flash hazard level?
Answer: The arc flash hazard label on the equipment and the facility's arc flash study
Arc flash labels on equipment and the facility's arc flash hazard analysis study provide the incident energy level, flash protection boundary, and required PPE category.
A worker notices that safety grounding cables were omitted before work began on a de-energized overhead transmission line. What risk does this create?
Answer: Risk of electrocution from induced voltage or accidental re-energization
Safety grounds protect workers from induced voltages from adjacent energized lines and from accidental re-energization by creating a low-impedance fault path that trips protective devices.
Under NFPA 70E, which of the following is classified as 'unqualified person' work that is permitted within the limited approach boundary?
Answer: Resetting a tripped GFCI receptacle
Resetting a tripped GFCI receptacle is a routine, low-risk action that does not require a qualified electrical worker, unlike tasks involving direct contact with energized conductors.
What is the correct way to handle an electrical worker who is in contact with an energized conductor and cannot release their grip?
Answer: Use a non-conductive object to push the worker away from the conductor
Rescuers must use non-conductive objects (wood, dry rope, fiberglass) to break contact because touching the victim directly transmits the current to the rescuer.
Which OSHA standard governs lockout/tagout procedures for the control of hazardous energy in general industry?
Answer: 29 CFR 1910.147
OSHA 29 CFR 1910.147 is the Control of Hazardous Energy (Lockout/Tagout) standard for general industry, covering procedures for servicing and maintaining equipment.
