Final answer:
The primary purpose of proper sharps disposal is to prevent injury and the spread of infections, as sharps are a significant biohazard. This is achieved by using designated containers and sterilization procedures before disposal.
Step-by-step explanation:
The primary purpose for the proper disposal of sharps is to prevent injury and the spread of infection to individuals who may come in contact with these items. Sharps, such as used needles and scalpel blades, can potentially harbor blood and other materials contaminated with disease-causing organisms, making them a significant biohazard. Proper disposal involves placing sharps in specially designed containers that are puncture-resistant and can be sealed securely. These containers are then handled according to protocols that ensure they are sterilized— typically through autoclaving—before final disposal.
Failure to properly dispose of sharps can lead to needle-stick injuries among waste handlers, healthcare workers, or even members of the public. Such accidents can transmit serious diseases, including HIV and hepatitis. Additionally, improper disposal practices can contribute to environmental pollution when biohazardous waste enters landfills or water systems without adequate treatment.
