What can be classified as Other Potentially Infectious Material (OPIM)?

  1. Saliva containing blood

  2. Tap water

  3. Sweat

  4. Tears without blood

The correct answer is: Saliva containing blood

Saliva containing blood can be classified as Other Potentially Infectious Material (OPIM) because it has the potential to transmit infectious diseases due to the presence of blood. Bloodborne pathogens can be present in saliva when it contains blood, making it a potential source of infection. It is important to handle and dispose of saliva containing blood carefully to prevent the spread of diseases. The other options, such as tap water, sweat, and tears without blood, do not typically contain enough pathogens to be classified as Other Potentially Infectious Material (OPIM) in the context of infection control and safety protocols.
