Final answer:
The statement is false. Needles and scalpels must be disposed of in specially designed sharps containers due to their biohazardous nature. These items cannot simply be thrown in the trash as they can cause harm.
Step-by-step explanation:
The statement 'Dispose of needles and scalpels in a plastic baggie, then place in the trash can.' is false. Disposing of needles, scalpels, and other sharp medical instruments in the trash can pose serious health risks to sanitation workers and the public. These items are considered biohazardous waste and should be disposed of in specially designed sharps containers. These containers are typically made of puncture-resistant plastic and can be sealed to prevent needle-stick injuries. Once full, the containers should be handled according to local regulations which often involve bringing them to a specified collection site for medical waste or a program for safe disposal.
