The short answer

Turn off the Power Safely

If water has entered your home or is rising, the first step is to shut off the main breaker, but only if you can reach it without stepping into water or touching wet surfaces. Stand on dry ground and use a dry wooden stick or tool to flip the switch. If the panel is wet or you have any doubt, leave it and call the power company to shut off service.

Never attempt to turn off power while standing in water, even a shallow puddle. Water conducts electricity, and contact can be fatal. If you cannot reach the breaker safely, evacuate and wait for help. Your local power company can disconnect service from outside, but that may take time, so leave the area if needed.

  • Check for standing water before approaching the panel.
  • Use only dry, non-conductive tools to flip the breaker.
  • If the panel is wet, do not touch it at all.
  • Evacuate if you cannot safely shut off power.
  • Call the power company from a safe location.

Avoid Floodwater Contact

Floodwater is often contaminated with sewage, chemicals, and debris, and it can hide live electrical currents from downed power lines. Stay out of the water whenever possible. If you must walk through it, wear rubber boots and gloves, but know that these do not fully protect you if the water is electrified.

Keep children and pets away from flooded areas. Do not use electrical appliances that have been submerged, even after they dry. Water can damage internal components and create shock hazards. Once the flood recedes, discard or have a professional service any electronics that got wet.

Check for Downed Lines

After a flood, downed power lines can be hidden under water or debris. Assume every wire is live. Never touch a downed line, and keep a distance of at least 30 feet. If you see one, report it to the power company immediately and warn others in the area.

Do not drive through flooded streets where power lines may be submerged. The water can conduct electricity through your vehicle. If your car is in contact with a downed line, stay inside and call for help. If you must exit, jump clear without touching the car and the ground at the same time.

After the Flood Recedes

Once the water is gone, do not restore power yourself. Have an electrician inspect your electrical panel, wiring, and outlets for damage. They can identify corrosion, frayed wires, or other hazards that could cause a fire or shock. This inspection is critical before you turn the breaker back on.

If your home has been flooded, the pros who handle flood damage cleanup can help with water extraction and drying. They can also coordinate with an electrician if needed. Check with your insurance company about coverage for electrical repairs; policies vary, and your insurer decides what is covered.

Stay Safe While Waiting

While waiting for power to be restored, use battery-powered lights instead of candles to avoid fire risks. Keep a flashlight and extra batteries handy. If you use a generator, place it outdoors and away from windows to prevent carbon monoxide poisoning. Never run a generator inside your home or garage.

Keep your refrigerator and freezer closed to preserve food as long as possible. If the power is out for more than four hours, discard perishable items that have been above 40F. When in doubt, throw it out. If you feel unwell from stress or exposure, see a doctor.

Frequently asked questions

Can I turn off the power if the breaker panel is wet?

No, never touch a wet breaker panel. Water conducts electricity, and you risk electrocution. If the panel is wet, leave it and evacuate. Call the power company to shut off service from outside. Your safety is more important than saving appliances.

What should I do with wet appliances after a flood?

Do not use any appliance that has been submerged. Water can damage wiring and create shock hazards. Once the flood recedes, have an electrician inspect them. Many can be repaired, but some may need to be replaced. Check with your insurance company about coverage.

Is it safe to walk through floodwater to leave my home?

It is safer to stay put if you are on high ground, but if you must leave, wear rubber boots and avoid moving water. Floodwater can carry electrical currents and contaminants. Move slowly and use a stick to probe for hazards. Do not let children or pets wade in it.
