Final answer:
Use an EPA-registered hospital disinfectant on tools and equipment that have come into contact with blood, adhering to strict disinfection protocols to prevent infection transmission.
Step-by-step explanation:
An EPA-registered hospital disinfectant should be used if tools, multi-use supplies, or equipment come into contact with blood. Blood is recognized as the greatest risk factor for the transmission of infections such as hepatitis B virus (HBV) and other pathogens. Health-care workers must take precautions, such as wearing gloves and face protection, and following strict disinfection protocols to prevent the spread of infection. When contaminations occur, immediate hand washing with detergent and warm water is recommended, followed by disinfection of affected surfaces with approved solutions, such as a 10% bleach solution suggested by the CDC for HBV. It's crucial to incinerate or autoclave contaminated waste correctly and ensure the meticulous cleaning and disinfection of instruments that might carry infectious agents.
