Addressing sewage spills in the home should be done carefully. Walls, hard-surfaced floors and many other household surfaces should be cleaned with soap and water and optionally disinfected with a solution of 1 cup of bleach to five gallons of water.
Do not mix ammonia cleansers with bleach as toxic vapors will form.
Wash all linens and clothing in hot water or dry-clean them. Items that cannot be washed or dry-cleaned, such as mattresses, carpeting and upholstered furniture, should be discarded. Remove and discard contaminated household materials that cannot be disinfected, such as wall coverings, cloth, rugs and drywall.
Protective clothing such as rubber boots and waterproof gloves should be worn during cleanup.
Once cleanup is complete it is important to dry out affected items to prevent the growth of mold.
For spills outside, disinfect the spill residue with regular garden lime. Sprinkle the lime onto the spill so the spill is dusted mostly white on the surface. If the residue is thicker in some places use a rake to mix the lime and the residue a little.
After a day, if the residue is thick in some places, rake up the thicker residue and place it in a trash bag for disposal with the other trash. Use a sprinkler or hose to water the lime and residue into the soil. Let it dry in the sun a day before allowing access to the area. If there is still white lime dust visible on the yard, water it in until the white dust is gone.
Proper hygiene is important for cleanup workers. Hands and fingers should be kept from the nose, mouth, eyes and ears. Workers should thoroughly wash their hands with soap and water before eating or drinking and after cleanup.
Fingernails should be kept short and foreign materials removed from nails with a stiff soapy brush. Fresh work clothes should not be stored with used work clothes. A shower is advisable after each workday.
