The Maine Emergency Management Agency on its Web site urged flood victims to use caution when returning to their homes as water recedes.

The potential dangers include electrical hazards, gas leaks, structural damage and unsafe drinking water.

Homeowners should open windows and doors to allow foul odors to evaporate before inspecting their houses.

Information on MEMA’s Web site advised that homeowners wear rubber gloves and rubber-soled shoes to avoid electrocution. They also should not turn on light or appliances. If the circuit breaker is in a flooded basement, the power company will need to turn off the electricity, MEMA advises. Homeowners also should make sure the circuits are dry before turning on the power.

Homeowners should knock down hanging plaster and watch foundations carefully because there is a danger of foundation walls collapsing if the basement is flooded. To prevent radical changes in pressure, one-third of the water per day should be pumped out of basements over a three-day period, MEMA advised.

No fresh food that has come in contact with floodwaters should be eaten, and water should be treated before drinking, according to the Web site.

MEMA also advises that flood victims keep detailed records and receipts of all flood-related expenses.
