Electrical Safety After Floods and Severe Storms

Avoid shock, fire, and equipment hazards by treating flooded electrical systems as unsafe until qualified inspection and clearance.
Assume wet systems are hazardous
Floodwater can energize surfaces and damage wiring, panels, outlets, appliances, batteries, and solar equipment. Never enter standing water where electricity may be present. Keep children and pets away.
Disconnect only from a dry place
If authorities advise shutting off power and the main disconnect can be reached without entering water, follow local instructions. If reaching it requires crossing water or a wet area, contact the utility, fire department, or a licensed electrician.
Avoid damaged equipment
Do not touch fallen service lines, sparking equipment, scorched outlets, or submerged appliances. Never connect a generator directly to household wiring without a professionally installed approved transfer system; backfeeding can electrocute workers and neighbors.
Require inspection before reuse
Have a qualified electrician evaluate flooded or damaged wiring and equipment before restoring power. Some devices require replacement rather than drying. Follow manufacturer directions and local code for panels, outlets, appliances, batteries, and chargers.
Use safe temporary lighting
Use battery-powered flashlights or lanterns. Avoid candles and fuel-burning lights around possible gas leaks, damaged buildings, or flammable debris. Wait for official clearance before cleanup.
Quick checklist
- Save relevant emergency, utility, and healthcare contacts.
- Keep required supplies accessible and check dates regularly.
- Practice the plan with household members and caregivers.
- Follow current directions from qualified local authorities.
Frequently asked questions
When should this plan be reviewed?
Review it at least twice a year and after a move, household change, medical change, equipment change, or local emergency.
What takes priority during a real event?
Current directions from emergency responders, utilities, public-health officials, and treating clinicians take priority over general guidance.
