What is the purpose of a GFCI device from a safety perspective?
Answer: To protect people from electric shock by detecting ground faults as small as 5 milliamps
GFCIs detect ground fault currents as low as 4-6 milliamps and trip within milliseconds to prevent fatal electric shock.
Which of the following best describes 'qualified person' under OSHA electrical standards?
Answer: Someone who has been trained to work on electrical systems and is aware of the hazards involved
OSHA defines a qualified person as one who has received specific training in and has demonstrated skills in the construction and operation of electrical equipment.
What is the voltage threshold above which NFPA 70E considers electrical work potentially hazardous?
Answer: 50V AC
NFPA 70E establishes 50 volts AC as the threshold at which electrical shock becomes a significant hazard requiring safety precautions.
What does the NFPA 70E standard primarily address?
Answer: Electrical safety in the workplace
NFPA 70E: Standard for Electrical Safety in the Workplace covers safe work practices, PPE requirements, and hazard analysis.
What color is typically used for safety labels indicating an electrical shock hazard?
Answer: Orange and black
Orange and black is the ANSI/OSHA standard color combination for warning labels indicating electrical shock hazards.
What is 'energized electrical work' as defined by NFPA 70E?
Answer: Work performed on or near live parts that have not been placed in an electrically safe work condition
Energized electrical work is any task performed on or near conductors or circuit parts that have not been de-energized and verified safe.
