Which statement is true about electrical and electronic safety precautions?

• A. All of the above
• B. Never work alone
• C. Never use steel wool or emery cloth on circuits
• D. Never repair energized circuits except in an emergency

Answer: (A)

Electrical safety is all about preventing harm by controlling energy in circuits and following safe procedures. The statements reflect solid precautions that reduce the risk of shock, burns, and arc flash. Never working alone means there’s someone to assist or call for help if something goes wrong, which is a key safety measure in any potentially hazardous task. Never using steel wool or emery cloth on circuits is important because metallic fibers can cause short circuits, shed conductive particles, or ignite if there’s an arc or heat. And never repairing energized circuits except in an emergency aligns with the principle of treating energized gear as dangerous; the safer approach is to de-energize, verify that it is off, and follow proper lockout/tagout procedures before working, reserving any energized action for dire emergencies only with appropriate precautions. So all of these are valid precautions, which is why the correct choice states that all of the above are true.
