Final answer:
Contaminated supplies that have been in contact with blood must be discarded in a biohazard bag because they are considered biohazardous materials. It is critical to follow proper disposal procedures, including sterilization by autoclave, to prevent the spread of infectious agents.
Step-by-step explanation:
Contaminated supplies coming in contact with blood should be discarded in a Biohazard bag. This is because these materials are considered biohazards, which are biological materials that could potentially make someone sick. Such materials could include disease-causing organisms like those found on used needles or in bacteria grown in a laboratory. It is important to recognize the international symbol for biohazards and to dispose of all waste materials according to safety guidelines. Contaminated waste must be sterilized, typically by autoclave, before it can be included in the waste stream to ensure that any potential pathogens are destroyed.
Sharps, such as needles, should also be placed in a sharps container designed for objects that can puncture or cut. Regular trash bins and recycling bins are not suitable for disposing of biohazard waste as they do not prevent the spread of infectious agents and do not comply with health and safety regulations.
