Blood that soaked in or spread. Stop cleaning and call a trauma cleanup company

Blood in carpet padding, mattresses or floor seams cannot be disinfected from the top, and hepatitis B stays infectious on surfaces for at least seven days.

Keep everyone out of the area. Do not scrub, shampoo or pull up materials yourself.

What is probably happening

The CDC's own guidance warns that even strong bleach may not fully inactivate virus in large quantities of blood. Volume changes the job.
Soft or porous materials that absorbed blood (carpet, padding, mattress, upholstered furniture, subfloor) are removed and disposed of as regulated waste, not cleaned.
A trauma cleanup crew removes, disinfects hard surfaces, checks what is underneath, and disposes through a permitted medical waste transporter.

Do this in the next five minutes

Get everyone, including pets, out of the room and close the door.
If the injured person is at hospital, let the cleanup wait. Nothing here is more urgent than they are.
Photograph the area from the doorway for the insurance claim.
Call your homeowners insurer. Sudden accidental damage is covered by most policies; ask specifically about biohazard cleanup.
Call two trauma cleanup companies and ask the questions below.

Do not

Do not rent a carpet cleaner. It drives blood deeper into padding and subfloor and contaminates the machine.
Do not cut out carpet yourself. Without gloves, eye protection and a disposal route, you are the one exposed.
Do not put blood-soaked material in the household trash. Medical waste disposal is regulated by your state's environmental and health departments.

Who to call

A trauma scene cleanup company

A carpet or restoration firm can replace flooring afterwards, but removal and lawful disposal of blood-soaked material is trauma cleanup work under OSHA's bloodborne pathogens standard.
