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: Understand India's biomedical waste color-coding system. Step 1: The Biomedical Waste Management Rules establish a color-coding system for efficient segregation, handling, and disposal of healthcare waste.
Step 2: Recognize each color's purpose.
Step 2:

(A) Green: For non-hazardous waste (e.g., kitchen waste, paper).
(B) Yellow: For highly critical waste: human anatomical waste, soiled waste (cotton, dressings), and chemical waste.
(C) Blue: For contaminated glass waste (vials, ampoules) and metallic body implants. Puncture-proof containers, often blue, hold sharps.
(D) Black: Traditionally for general waste, but recent guidelines prefer Green. All four colors have historically been part of the system. Newer rules include White (sharps) and Red (contaminated recyclable plastic).
Step 3: Determine the relevant colors.
Step 3: Green (general), Yellow (infectious), and Blue (glassware) are major categories. Black was also used for general waste. Therefore, A, B, C, and D are all part of the biomedical waste color-coding system.
