Separation at the Source:

• Segregate waste immediately at the point of generation to avoid mixing.
• Store biological and chemical waste in separate, dedicated areas to minimize the risk of contamination.

Use of Secondary Containment:

• Place waste containers in secondary containment trays to prevent spills or leaks.
• Ensure the secondary containment for chemical waste is compatible with the chemicals stored.

Handling and Labeling:

• Handle biological waste using PPE, including gloves, lab coats, and face shields.
• Label all waste containers with:
  • Type of waste
  • Date of generation
  • Hazard symbols, if applicable

4.3 Collection and Storage

1. Collection of Biological Waste:
   • Transfer biological waste to designated yellow bags or bins with biohazard symbols.
   • Ensure bags are sealed to prevent leakage and stored in refrigerated areas if not disposed of immediately.

2. Collection of Chemical Waste:
   • Use compatible, leak-proof containers for chemical waste.
   • Store hazardous and non-hazardous chemical waste in separate, labeled areas with restricted access.
3. Storage Guidelines:
   • Store segregated waste in ventilated, temperature-controlled storage areas.
   • Ensure biological waste is not stored for more than 48 hours without treatment.
   • Maintain chemical waste within designated storage time limits, as specified by regulations.

4.4 Transportation of Segregated Waste

1. Internal Transport:
   • Use spill-proof, dedicated trolleys for biological and chemical waste to prevent cross-contamination.
   • Follow predefined waste transport routes to minimize exposure risks.

2. External Transport:
   • Coordinate with licensed waste disposal vendors for the safe transportation of waste.
   • Ensure transport manifests are accurately completed and retained for compliance.

4.5 Waste Treatment and Disposal

1. Biological Waste Treatment:
   • Autoclave infectious waste before disposal to kill pathogens.
   • Dispose of treated waste through incineration or as per regulatory guidelines.

2. Chemical Waste Disposal:
   • Neutralize acids and bases before disposal, if feasible.
   • Dispose of hazardous chemicals through licensed hazardous waste disposal facilities.

4.6 Emergency Management

1. Spills:
   • Handle biological waste spills using disinfectants and absorbent materials.
   • Contain chemical spills using appropriate neutralizers and spill kits.

2. Incident Reporting:
   • Document all incidents in the Waste Incident Log (Annexure 1).

4.7 Training and Compliance

1. Personnel Training:
   • Train employees on segregation practices, use of PPE, and emergency response protocols.
