Segregation Guidelines:

• Segregate waste immediately at the source of generation.
• Label all waste containers with the appropriate waste category and hazard symbol.
• Do not mix hazardous and non-hazardous waste in the same container.

4.3 Collection and Storage of Laboratory Waste

1. Collection Process:
   • Use puncture-proof and leak-proof containers for chemical, biological, and sharps waste.
   • Ensure all waste containers are sealed properly before transportation.
   • Replace containers when they are 3/4 full to avoid overfilling.

2. Temporary Storage Guidelines:
   • Designate separate, ventilated storage areas for each waste category.
   • Ensure hazardous chemical and biological waste is stored securely and away from incompatible substances.
   • Keep glass and sharp waste containers in stable, clearly marked locations to avoid accidents.
3. Labeling and Documentation:
   • Label containers with:
     • Waste type (chemical, biological, glass, sharps)
     • Hazard warnings (biohazard, toxic, flammable)
     • Collection date
   • Record waste details in the Laboratory Waste Log (Annexure 1).

4.4 Disposal of Laboratory Waste

1. Chemical Waste:
   • Dispose of chemical waste through authorized hazardous waste vendors.
   • Neutralize acids and bases before disposal under fume hoods.
   • Document disposal using a Chemical Waste Manifest (Annexure 2).

2. Biological Waste:
   • Autoclave biological waste at 121°C for 30 minutes before disposal.
   • Incinerate biohazardous waste at approved biomedical waste disposal facilities.
3. Glass Waste:
   • Decontaminate glassware with disinfectant before disposal.
   • Dispose of uncontaminated glassware in blue-labeled containers.
4. Sharps Waste:
   • Collect sharps in white, puncture-proof containers.
   • Send for incineration or destruction by authorized waste disposal agencies.
5. General Waste:
   • Dispose of general laboratory waste via municipal waste collection systems.
   • Recycle uncontaminated paper, plastic, and packaging materials wherever possible.

4.5 Emergency Spill Management

1. Chemical Spills:
   • Evacuate the area and use spill kits to contain and neutralize the spill.
   • Dispose of cleanup materials as hazardous waste.

   • Report the incident and seek medical attention.

4.6 Record-Keeping and Reporting

1. Maintain records of all laboratory waste collection, storage, and disposal activities.
2. Use the Laboratory Waste Log (Annexure 1) to document details of waste generation and disposal.
3. Submit waste disposal certificates provided by authorized vendors to the Safety Officer.
