What type of waste is primarily held in red bags or containers?

  1. Infectious waste

  2. Biohazard waste

  3. Regular trash

  4. Reusable materials

The correct answer is: Biohazard waste

Red bags or containers are specifically used for biohazard waste, which includes materials that are potentially infectious or pose a health risk to humans or the environment. This type of waste can include items such as used needles, blood-soaked dressings, and other materials that may carry pathogens. The color coding with red bags is an industry-standard practice to easily identify and segregate waste that must be handled with special care to prevent contamination or accidental exposure. While infectious waste is a subset of biohazard waste, the terminology used in the choice is specific to broader biohazard categories, which is why the identification of red bags with biohazard waste is accurate. Regular trash and reusable materials are not categorized this way and do not require the special handling procedures that biohazard waste mandates.
