Safety Precautions When Returning Home
When returning to your home after a flood:

• Watch for debris on the road while driving.
• Make sure the main electrical switch to your home is off before entering the structure.
• Be careful when entering a structure that has been damaged.
• If you suspect a gas leak, leave immediately and notify the gas company.
• If possible, listen to the radio or contact authorities to find out whether sewage lines are intact before turning on the water or using the toilet.
• Report utility damage to the proper authorities.

Mosquitoes
As floodwaters recede, mosquitoes will breed in pools of stagnant water left behind. Mosquitoes can transmit a number of diseases, including West Nile virus. Protect yourself by:

• Remove sources of standing water around your home. This includes water in puddles, tires, wading pools and planters
• Wear light-colored clothing with long sleeves and long pants outdoors, especially in the morning and evenings when mosquito activity is at its peak.
• Use insect repellent containing DEET or Picaridin for greatest effectiveness. Follow label directions when applying the product.

Gas Leaks
If you smell gas or suspect a leak, turn off the main gas valve, open all windows, and leave the house immediately. Notify the gas company, the police, fire departments, or State Fire Marshal's office, and do not turn on the lights, light matches, smoke, or do anything that could cause a spark. Do not return to the house until you are told it is safe to do so.

Electrical Damage
Your electrical system may have been damaged. If you see frayed wiring or sparks when you restore power, or if there is an odor of something burning but no visible fire, you should immediately shut off the electrical system at the main circuit breaker. All electrical equipment and appliances must be completely dry before returning them to service. It is advisable to have a certified electrician check these items if there is any question.

Other Injury-Prevention Measures
To avoid other flood-related injuries, you should avoid all power lines, particularly those in water; and avoid wading in water as broken glass, metal fragments, and other debris may be present in the water.

Cleanup
Once you have established that no structural, electrical, or gas-related hazards exist in your home, dry and disinfect all materials inside the house to prevent the growth of mold and mildew.

Walls, hard-surfaced floors, and many other household surfaces should be cleaned with soap and water and disinfected with a solution of one cup of bleach to five gallons of water. Be particularly careful to thoroughly disinfect surfaces that may come in contact with food, such as counter tops, pantry shelves, refrigerators, etc. Areas where small children play should also be carefully cleaned. Wash all linens and clothing in hot water, or dry clean them. For items that cannot be washed or dry cleaned, such as mattresses and upholstered furniture, air dry them in the sun and then spray them thoroughly with a disinfectant. Steam clean all carpeting. If there has been a backflow of sewage into the house, wear rubber boots and waterproof gloves during cleanup. Remove and discard contaminated household materials that cannot be disinfected such as wall coverings, cloth, rugs, and drywall.

• Mold: Questions and Answers

Water Quality
Flooding can contaminate the public water supply. Drinking contaminated water may cause illness. You cannot assume that the water in the affected area is safe to drink. Water treatment plants may not be operating; even if they are, flooding can contaminate water lines. Listen for public announcements about the safety of the water supply. If your well has been flooded, it needs to be tested and disinfected after the flood waters recede. Questions about testing should be directed to your local or state health department.

Water for Drinking and Cooking
Safe drinking water includes bottled, boiled, or treated water. Your state or local health department can make specific recommendations for boiling or treating drinking water in your area. Here are some general rules concerning water for drinking and cooking:

	Do not use contaminated water to wash dishes, brush your teeth, wash and prepare food, or make ice.
	If you use bottled water, know where it came from. Otherwise, water should be boiled or treated before use. Drink only bottled, boiled, or treated water until your supply is tested and found safe.
	Boiling water kills harmful bacteria and parasites; bringing water to a rolling boil for 1 minute will kill most organisms.
	When boiling is not possible, water may also be treated with chlorine or iodine tablets, or by mixing six drops (1/8 teaspoon) of unscented, ordinary household chlorine bleach (5.25% sodium hypochlorite) per gallon of water. If the water is cloudy, use twelve drops (1/4 teaspoon). Mix the solution thoroughly, and let stand for about 30 minutes. These treatments will not kill parasitic organisms, however.
	Containers for water should be rinsed with a bleach solution before re-using them. Use water storage tanks and other types of containers with caution. For example, fire truck storage tanks, as well as previously used cans or bottles can be contaminated with microbes or chemicals.
	Do not rely on untested devices for decontaminating water.

Public Water Systems
Precautions for water supply operators to take to prevent contamination of public water systems.

Disinfecting Wells
If you suspect that your well may be contaminated by floodwaters, review our disinfection procedures below or contact your local health department or agriculture extension agent for specific advice.

• Private Water Well Disinfection Procedure

Onsite Wastewater Systems
If your residence or facility utilizes a septic tank or Advanced Treatment System (aerobic treatment unit) as a means to treat and dispose of your wastewater, then you will need to follow the precautions and procedures below before and after a flood event.

• Precautions and Recovery Procedure for On-site Wastewater Systems

Sanitation and Hygiene
It is critical for you to remember to practice basic hygiene during the emergency period. Always wash your hands with soap and water that has been boiled or disinfected:

	before preparing or eating food;
	after toilet use;
	after participating in cleanup activities; and
	after handling articles contaminated with floodwater or sewage.

Floodwater may contain fecal material from overflowing sewage systems and agricultural and industrial waste. Although skin contact with floodwater does not, by itself, pose a serious health risk, there is risk of disease from eating or drinking anything contaminated with floodwater. If you have any open cuts or sores that will be exposed to floodwater, keep them as clean as possible by washing them with soap and applying an antibiotic ointment to discourage infection. If a wound develops redness, swelling, or drainage, seek immediate medical attention.

Do not allow children to play in floodwater areas. Wash children's hands frequently (always before meals), and do not allow children to play with floodwater-contaminated toys that have not been disinfected. You can disinfect toys using a solution of one cup of bleach in five gallons of water.

Downed Powerlines
Do not attempt to move or repair downed powerlines. Do not drive through standing water if downed powerlines are in the water.

Animals
Wild or stray domestic animals can pose a danger. Remember, most animals are disoriented and displaced, too. Do not corner an animal. If an animal must be removed, contact your local animal control authorities. If you are bitten by any animal, seek immediate medical attention. If you are bitten by a snake, first try to accurately identify the type of snake so that, if poisonous, the correct anti-venom can be administered. Do not cut the wound or attempt to suck the venom out.

Drowning
Swiftly moving waters pose a great danger. People who enter moving water with their cars, or who get on boats are at a grave risk of drowning, regardless of their ability to swim. Even very shallow water that is moving swiftly can be deadly. Cars or other vehicles do not provide adequate protection. Cars can be swept away or may break down in moving water. Be alert and follow hazard warnings on roadways or those broadcast by the media. Police and public works departments should be contacted for up-to-date information regarding safe roadways.

Chemical Hazards
Be aware of potential chemical hazards you may encounter when returning to your home. Flood waters may have moved or buried hazardous chemical container of solvents or other industrial chemicals. Contact your local fire department about inspecting and removing hazardous chemical containers. Avoid inhaling chemical fumes.

If any propane tanks (whether 20-lb. tanks from a gas grill or household propane tanks) are discovered, do not attempt to move them yourself. These represent a very real danger of fire or explosion, and if any are found, the fire department, police, or your State Fire Marshal's office should be contacted immediately.

Car batteries, while flooded may still contain an electrical charge and should be removed with extreme caution by using insulated gloves. Avoid coming in contact with any acid that may have spilled from a damaged car battery.
