Something else involving blood, body fluids, waste or contamination
The site's rule for this trade is that a surface that looks clean is not evidence that it is, and hepatitis B stays infectious on surfaces for at least seven days.
What is probably happening
- If it involves blood, body fluids, human or animal waste, sharps, or a chemical you cannot identify, it is a biohazard question and a trauma cleanup or restoration company is the right first call.
- If it is water only, with no sewage, the water damage page is the better fit. If it is mold after a leak, the mold page.
- If it is a crime, police first, and remember that every state has a crime victim compensation program that can help pay for cleanup.
Do this in the next five minutes
- Keep children and pets out of the area and close the door.
- Do not sweep, vacuum, or scrub anything dry. Wet cleanup with gloves is safer than dry.
- Photograph the area from the doorway.
- Call your homeowners insurer and describe what happened.
- Call two biohazard cleanup companies. Ask the questions below, then the seven questions that apply to every contractor.
Do not
- Do not let a company start without a written scope.
- Do not pay cash up front.
- Do not accept a quote that will not say how the waste is disposed of.
