Your University Outreach and Extension center can help with food and water safety, cleanup and restoration questions or referrals. Disconnect main switch and all circuits. Remove covers and clean all outlets and fuse or multi-breaker boxes. Have an electrician check for ground faults and other unsafe conditions and equipment before reconnecting systems. Equipment and wiring that appears to be safe soon after flooding may fail prematurely and cause a fire or shock hazard.
Replacement is often the best option.
Circuit breakers that have been submerged should be replaced. Until your local water utility or county health department declares your water source safe, purify all water, not only for drinking and cooking, but also for washing any part of the body. Boil vigorously for 3 minutes. Discard all foods, including garden produce, that have come in contact with flood waters. Only foods sealed in airtight metal cans that are not bulging or damaged and have been properly sanitized can be saved.
