Question

The colour coding of waste categories for disposal of biomedical waste include:
A. Green
B. Yellow
C. Blue
D. Black
Choose the correct answer from the options given below:

• A. A, B and D only
• B. B and C only
• C. A, B, and C
• D. A, B, C and D

Hint:

Remember the main hazardous categories: \textbf{Yellow} for infectious/anatomical waste, \textbf{Red} for plastic waste, \textbf{White} for sharps, and \textbf{Blue} for glassware. \textbf{Green} is for general waste.

Answer 1

The Correct Option is D

Step 1: Recall the color-coding system for biomedical waste management in India. Step 1: The Biomedical Waste Management Rules specify a color-coding system to ensure proper segregation, handling, and disposal of different types of healthcare waste.
Step 2: Identify the use of each color mentioned.
Step 2:

(A) Green: Used for general, non-hazardous waste (e.g., kitchen waste, paper).
(B) Yellow: The most critical category, used for human anatomical waste, soiled waste (cotton, dressings), and chemical waste.
(C) Blue: Used for contaminated glass waste (vials, ampoules) and metallic body implants. Puncture-proof containers, often blue-marked, are used for sharps.
(D) Black: While its use has been phased out or modified in recent guidelines in favor of Green for general waste, it was traditionally used for general waste and is still referenced in older systems. The guidelines have evolved, but historically all four colors have been part of the system. More recent rules also specify White (for sharps) and Red (for contaminated recyclable plastic).
Step 3: Conclude which colors are part of the system.
Step 3: Given that Green (general), Yellow (infectious), and Blue (glassware) are all currently or have been major categories, and Black was also used for general waste, all four colors are relevant to the color-coding system of biomedical waste. Therefore, A, B, C, and D are all included.
