Study Notes

Handling Biological Waste

  • Proper handling of biological waste is crucial after experiments
  • Follows a specific procedure to avoid contamination
  • Waste categorized into 4 types (A, B, C, and D)
  • Each category requires specific disposal methods

Category A Waste

  • Items like scalpel, glass slides, and other sharp objects
  • Placed into yellow biohazard bags and sealed properly with autoclave
  • Autoclaving at 121 degrees Celsius for 15-20 minutes essential to sterilization

Category B Waste

  • Biological materials not included in category A, such as animal tissues
  • Placed into yellow biohazard bags
  • Autoclaving necessary for sterilization

Category C Waste

  • Biological materials from plants (roots, stems, leaves)
  • Placed in yellow biohazard bags and tightly sealed
  • Use autoclave for sterilization

Category D Waste

  • Materials like culture media (containing cells), blood, tissue samples, and others.
  • Place in sealed yellow biohazard containers
  • Autoclaving is necessary to sterilize waste
  • Prior sterilization is vital due to the materials' ability to carry pathogens
