Cleaning Up Your Residence After a Flood
This following outlines the steps you should take
to protect yourself and your family as you clean up after a flood.
Before you begin: When returning to your home after a flood, be
aware that flood water contains contaminants, such as sewage. Sharp
objects, debris, and other safety hazards may have been washed into the area
by flood waters. Before entering to clean an area, make sure the building is
structurally safe and that the electrical service has been inspected and is
safe to use. Also, be sure that all gas appliances are inspected and
approved for use.
Step 1: Gather cleaning tools. Buckets, mops, trash bags, cleaning
rags, ammonia-free household cleaner, laundry detergent, dish soap,
measuring cups, and household bleach (5% chlorine).
Step 2: Set up a hand washing area for hand washing throughout the
cleaning process. For rinsing hands, use water that has been boiled for
1 minute, or make a solution of ¼ teaspoon of household bleach per 1 gallon
Step 3: Protect yourself and your family during cleaning.
- Keep children and pets out of the affected area until cleanup has
- Wear protective equipment, including rubber boots, rubber gloves
that cover most of the arm, disposable coveralls, N-95 face mask
(respirator), and eye protection.
- Wear earplugs or protective headphones to reduce risk from equipment
- Seek immediate medical attention if you become injured or ill.
Step 4: Inspect the building.
- Stay away from damaged buildings or structures until they have been
inspected for structural safety.
- Wait to return to buildings during daylight hours, when it is easier
to avoid hazards, particularly if the electricity is off and you have no
- Check and clean heating, ventilating, and air-conditioning systems
- Fix any water leaks.
- If using an onsite private sewage system, your system must be
inspected and serviced prior to using an in-home washing machine.
Step 5: Remove contaminated items that cannot be cleaned/salvaged.
Items that cannot be washed and disinfected may have to be removed and
disposed of if they were contaminated with sewage or flood waters. This
- carpet padding,
- upholstered furniture,
- stuffed animals,
- baby toys,
- foam-rubber items,
- wall coverings, most paper products, as they cannot be properly
Step 6: Clean.
Note: Never mix bleach and ammonia, or bleach and acids. This creates
toxic gases that are dangerous and can cause serious injury.
- Help the drying process by using fans, air conditioning units, and
- To clean hard surfaces that may have been in contact with floodwater
(like flooring, concrete, molding, wood and metal furniture,
countertops, appliances, sinks, and other plumbing fixtures): First,
wash with a household cleaner (non-ammonia) and clean water. Next,
disinfect with a mixture of 1 cup of bleach in 5 gallons of water. Allow
to air dry.
- To remove observed mold: Mix 1 cup of bleach in 1 gallon of water,
wash the item with the bleach mixture, scrub rough surfaces with a stiff
brush, rinse the item with clean water, then allow to dry.
- To wash clothing: Wash any clothes contaminated with flood or sewage
water (including clothes worn during cleanup) in hot water and laundry
detergent. It is recommended that a commercial laundromat be used for
washing large quantities of clothes and linens. Wash contaminated
clothes separately from uncontaminated clothes and linens.
- For more information: See the handout entitled “Cleaning and
Sanitizing with Bleach after an Emergency.”
Step 7: Additional precautions when cleaning around /outside the
- Wash Your Hands Regularly! After all cleanup activities, be
sure to wash your hands to avoid ingesting bacteria and viruses, other
waterborne diseases, or hazardous materials. Use alcohol-based gel hand
sanitizer after thoroughly washing hands.
- Avoid smoking or using open flames until you are assured that all
gas utilities, appliances, and fixtures are in proper working condition.
- Have at least one fire extinguisher, with a UL rating of at least
10A, at every cleanup job.
- Use teams of two or more people to move bulky objects. Avoid lifting
any material that weighs more than 50 pounds (per person).
- When using a chain saw, operate the saw according to the
manufacturer's instructions, wear appropriate protective equipment,
avoid contact with power lines, be sure that bystanders are at a safe
distance, and take extra care in cutting trees or branches that have
gotten bent or caught under another object.
- In hot weather, try to stay cool by taking breaks in shaded areas or
in cool rooms, drinking water, and wearing light and loose-fitting
clothing when not engaged in cleaning and sanitizing. Do outdoor
activities during cooler hours.
- Dispose of debris, tree limbs, furniture, mattresses, and large or
bulky items following instructions provided by your local community
