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
