With Hurricane Ike approaching the Texas Gulf Coast and threatening to grow stronger, the Cleveland County Health Department has issued the following safety precautions in case of floods.

Water

Watch for news media announcements about the safety of public drinking water supplies. Follow "boil water" alerts that may be issued by the Oklahoma Department of Environmental Quality. Take no chances on water from an unknown source, officials said.

Persons under boil water alerts and persons with private wells that may have been contaminated by floodwater should use only bottled, boiled or treated water until water has been tested and found safe.

If boiling water for drinking purposes, allow it to boil for at least one minute. Water also may be disinfected with chlorine or iodine (follow package directions) or with ordinary household bleach -- one-eighth teaspoon (about eight drops) per gallon of water. Sterilize water containers and drinking vessels with a solution of household bleach, officials said.

Food

Do not eat foods that have been in contact with floodwater.

If electricity has been off, refrigerated food may have spoiled. Discard any food that has been at room temperature for more than two hours or if it has an unusual odor or color. Thawed foods from freezers may be safe for consumption or refreezing if still partially frozen or "refrigerator cold."

Babies on formula should be given ready-to-feed formula or powdered formula prepared with bottled drinking water.

Wash hands with soap and disinfected water before eating or handling foods, after clean-up work and after handling floodwater-contaminated items.

Environmental hazards

Snakes and other wildlife may seek shelter in trees, homes and vehicles. Bats are often injured in heavy rains and winds. Do not handle these or other wildlife and be certain to seek immediate treatment if bitten or injured by an animal. Beware of displaced pets.

Return home in daylight for best visibility and to avoid using unsafe power sources. Do not use lanterns or torches until after the premises are safe from gas leaks.

Standing water after floods is a breeding place for mosquitoes. Drain all standing water and empty water from outdoor items such as old tires, cans and flowerpot bases. Protect yourself with an appropriate insect repellent.

Let no one re-enter a home while flooded unless the main electrical switch has been turned off.
