Cleaning Up After a Disaster (PDF: 172KB/3 pages)
This Web page summarizes handwashing, cleaning of household structure and contents, and food safety measures after a disaster.
Simple, basic hygiene – handwashing – is the single most important thing you can do to protect your health when you clean up after a disaster.
Be sure to wash your hands:
- After you touch any surfaces or objects that may have been in contact with debris or other contaminated material; and
- Before you eat or drink, use the bathroom, or touch your hands to your face.
- Wash Your Hands Thoroughly and Do It Often!
What if there is no running water?
- Transport and store clean water in clean plastic containers.
- Get a beverage cooler equipped with a spigot – and keep it filled with clean water for handwashing.
What if the water is contaminated?
- If the water might not be safe, add one tablespoon of bleach to one gallon of water before you use it to wash your hands.
How do I get my home clean?
Thoroughly remove moisture to avoid the growth of mold.
If you have moisture in your home:
- Use outside air to dry your home.
- Open windows and doors or use exhaust fans.
- Use a room dehumidifier, if available, and empty it often.
Water in or on walls and other surfaces
- Release any water or mud trapped in wall, ceiling or floor cavities.
- Open, clean, decontaminate and thoroughly dry cavities in walls, ceilings, and floors.
- Walls must dry from the inside out.
- Remove moisture and debris from all surfaces and get surface materials dry within 24-48 hours after flooding, or as soon as you are allowed into the building.
- Remove all interior wall finishing materials (e.g., wallpaper, wallboard, paneling) and insulation.
- Throw out any wet insulation. Discard other materials that cannot be cleaned and dried.
- Do not paint, or replace ceiling, wall tile or flooring until all enclosed spaces are completely dry, to avoid the growth of mold.

Salvaging Household Items
When in doubt, throw it out!
If you have wet carpeting:
- Pull up waterlogged carpet immediately, to prevent any further floor damage.
- Carpet pads cannot be saved - they must be removed and discarded.
- Attempt to save carpets or throw rugs only if they would be very expensive to replace.
- Clean and dry your floors (and sub-flooring) thoroughly before recarpeting.
If you have wet floors or woodwork:
- Remove any moisture or debris;
- Scrub floors and woodwork within 48 hours, using a stiff brush, water, detergent and disinfectant (See, “Use of Bleach”); and
- Allow all wood to dry thoroughly.
If you have wet furniture:
- Discard upholstered furniture if it has been exposed to water or contaminated material;
- Clean, rinse and disinfect wood furniture; and
- Place wood furniture outside in a shady area so it will dry slowly.
If any materials are still wet or moist after 24-48 hours, you should assume they have mold growing on them.
Disinfect floors or wood surfaces using a solution of ¼ - ½ cup bleach in a gallon of water.
If mold has already begun to grow, use a stronger solution – approximately ½ gallon of bleach to a five-gallon pail of water in a well-ventilated area.

Discard items in soft packaging or screw-top glass bottles that may have touched floodwater, or been in contact with contaminated material. Commercially canned goods in metal cans or rigid plastic can sometimes be saved. See, “Disaster Quick Tips: Basic Food Safety (PDF: 43KB/2 pages)”
