Giải thích
Cord inspection, one appliance per outlet, clear walkways, and grasping the plug prevent shock, fire, and trip hazards, and equipment should be unplugged when not in use. Overloading an outlet is a leading cause of salon electrical fires. Touching a plugged-in device with wet hands risks electrocution, and leaving units powered overnight is both a fire and an energy hazard.
