Introduction
According to the U.S. Department of Health, in 2017 there were almost two million emergency department (ED) visits due to unintentional/accidental cuts, piercings or nose bleeds that resulted in hospital admissions. That's about one in every five trips.
Throughout my career as an automotive technician, instructor, school administrator and avid DIYer, I've had or encountered too many stitch-worthy wounds that left a trail or puddle of blood.
Unfortunately, blood and other bodily fluids (vomit and urine) carry harmful biological pathogens, making them some of the most hazardous and nasty substances to clean up. Disinfecting wipes only work for cleaning a drop or two of blood from a minor nick or cut.
Blood spills larger than nine inches in diameter (about the size of a dinner plate) must be thoroughly cleaned and sanitized, and the fluids and materials used to clean it must be disposed of properly. Cleaning large blood spills on hard, non-porous surfaces differs from the treatment of carpet and other soft surfaces.
Following U.S. Department of Labor, Occupational Safety and Health Administration (OSHA) health standards, employers are required to provide information and training to staff "to prevent contact with blood or other potentially infectious materials." If you receive this type of training, it will help you remediate a large blood spill, no matter where you encounter it.
You can buy a pre-packaged blood spill kit for less than $50. But beware: These are for small spill clean-ups, and they lack the supplies to fully clean and disinfect a larger spill. You probably have most of the tools and materials you'll need in your garage or workshop already.
Doing this cleanup yourself can easily save you hundreds of dollars, because the mess will dry and worsen while you wait for the pros.
