Question

All of the following are true about biomedical waste disposal EXCEPT:

• A. Human anatomical waste is disposed in a yellow bag
• B. Red bag contents can be a potential source of infection
• C. Black bag is used for incineration ash
• D. Blue bag contents are disposed in secure landfill

Hint:

Glassware in the blue category is recycled after disinfection, not landfilled.

Answer 1

The Correct Option is D

This is an except question on colour-coded biomedical waste handling, so we accept the three correct statements and flag the wrong one. Anatomical human waste goes into the yellow stream destined for incineration, making the first statement valid. The red category collects contaminated recyclable plastics like used tubing and IV sets, and because these items are soiled with body fluids they are indeed potentially infectious, validating the second statement. Black bags in this scheme accommodate general or ash type discards, which fits the third statement. The blue category, however, is reserved for glassware and metallic sharps that are disinfected and then sent for recycling rather than buried in a secure landfill. Burial in a secure landfill is the route for certain treated or cytotoxic residues, not for blue bag glass. So the statement that does not hold true is the one about blue bag contents going to a secure landfill. \[\boxed{\text{Blue bag contents are disposed in secure landfill}}\]
