– Working near power supplies
• Look carefully for possible hazards in your work area, such as moist floors, ungrounded power
extension cables, frayed power cords, and missing safety grounds.
• Do not work alone if hazardous conditions exist.
• Never assume that power is disconnected from a circuit. Always check.
