Step 1: Recall the colour code of the 2016 biomedical waste rules: yellow, red, blue and white (translucent).
Step 2: The yellow category covers human and animal anatomical waste, soiled waste, expired or discarded medicines, chemical waste (solid and liquid) and cytotoxic waste, and laboratory or microbiology waste.
Step 3: Chemical liquid waste, including discarded or used chemicals and liquid body secretions, falls in this yellow category. Cytotoxic chemical waste carries an additional CYTOTOXIC label.
The other bins differ: red is for contaminated recyclable plastics (tubing, IV sets), blue is for glassware and metallic sharps, white (translucent puncture-proof) is for needles and sharps.
So chemical liquid waste goes in the yellow bin.
