The National TB Elimination Programme (NTEP) utilizes different coloured bags for the segregation of waste generated in TB laboratory settings as shown in the table below.

 

Table: Waste Segregated and Collected According to Colour-coded Bags

Yellow bag:

  • Broomsticks
  • Parafilm tape & plastic bag – contaminated with samples
  • Löwenstein-Jensen (LJ) media without the bottle
  • Microbial sample/ blood/ body fluids contaminated paper/ cotton/ swab
  • Blood bags
  • Microbiological cultures Truenat chips (MTB/ Rif)
  • Used mask/ gowns
  • Expired medicines/ drugs/ antibiotics 

 

Red bag:

  • Specimen collection tubes
  • Sputum cups
  • Cartridge Based Nucleic Acid Amplification Test (NAAT)/ Truenat cartridges
  • Infected plastic
  • Contaminated tips
  • Pasteur pipettes
  • Polymerase Chain Reaction (PCR) tubes
  • Mycobacteria Growth Indicator Tube (MGIT) tubes
  • Disposable LJ tubes
  • Contaminated falcon tubes
  • Used gloves
  • Contaminated droppers
  • Empty Cartridge-based Nucleic Acid Amplification Test (CBNAAT) reagent bottles

Blue bag:

Glass slide in Truenat machine and used microscopy slides. Slides should not be broken.

 

 

All these bags are to be labelled with the Biohazard logo (figure below) on them.

  • Waste generated in the Culture Drug Susceptibility Testing (CDST) laboratories is autoclaved prior to segregation in colour-coded bags.
  • The biohazard materials are collected and handed over to handlers authorized by the pollution control board.
  • Personnel handling/segregating biomedical wastes must use appropriate Personal Protective Equipment (PPE) and should be trained in spill management.
