NEET PG High-Yield: BMW Management Cycle
The biomedical waste management process is a strictly regulated sequence designed to prevent occupational exposure and environmental contamination.
The Management Process
| Stage | Key Actions |
|---|---|
| Collection | Point-of-generation segregation using color-coded bags/containers. No manual sorting allowed. |
| Storage | Temporary storage in a secured, restricted-access, and marked area. Max time: 48 hours. |
| Transport | Transport in dedicated, leak-proof, covered vehicles with clear labeling and “Biohazard” signage. |
| Treatment | Processing via authorized methods (Incineration, Autoclave, Microwaving, Shredding). |
Treatment Technologies
- Incineration: High-temperature (1050°C for the incinerator primary chamber) thermal destruction; mandatory for yellow category waste.
- Autoclaving: Moist heat disinfection (121°C at 15 psi for 60 min); used for red/white categories.
- Shredding: Mandatory for sharps and plastics to ensure they are rendered non-reusable.
High-Yield NEET PG Pearls:
- Final Disposal: Treated residual waste (e.g., incinerator ash) is sent to a Secured Sanitary Landfill.
- Common Failure Point: Improper segregation at the ward level is the most common cause of management system failure.
- Record Keeping: Facilities must maintain a “BMW Register” for inspection by pollution control boards.
