Always assume that all overhead wires are energized. Never assume that a wire is safe to touch even if it is down or appears to be insulated.
Never touch an overhead power line that has fallen down. Report fallen electrical lines to your electrical utility company.
Stay at least 10 feet (3 meters) away from overhead wires during cleanup and other activities. Survey the area for overhead wires before starting to work.
If an overhead wire falls across your vehicle while you are driving, stay inside the vehicle and continue to drive away from the line. If the engine stalls, do not leave your vehicle. Warn people not to touch the vehicle or the wire. Call or ask someone to call the local electric utility company and emergency services.
Never use electrical equipment while you are touching water.
Do not attempt to repair electrical wires or equipment unless qualified and authorized.
If electrical equipment that has gotten wet, have it inspected by a qualified electrician before energizing it.
When working in moist locations, inspect electric cables and equipment to make sure that they are free of defects, and use a ground-fault circuit interrupter (GFCI).
