In hospital waste, which category contains needles and scalpels?

• A. Biological specimens
• B. Sharps
• C. Radioactive medical waste
• D. Infectious material

Answer: (B)

Classifying hospital waste by risk and handling requirements. Needles and scalpels are sharp, rigid objects that can puncture skin and cause injuries or transmit bloodborne pathogens. Because of this puncture risk, they go into the sharps category and are disposed of in puncture‑resistant sharps containers, with specific handling to prevent needlestick injuries. They aren’t categorized as biological specimens, which refers to the actual collected materials like tissues or fluids; they aren’t radioactive medical waste, which involves radioactive materials; and while sharps can be contaminated with infectious material, the defining attribute for their category is the potential for injury from sharp objects, not the type of infectious contaminant.
