It is the clear responsibility of all research workers
to ensure the safe and correct disposal of all
wastes produced in the course of their work.
Improper and irresponsible disposal of biological
wastes down drains or into the atmosphere is
forbidden by law
o [Environmental Quality Act 1974, Environmental Quality
(Scheduled Wastes) Regulations 1989; Biosafety Act
2007].
Proper segregation of laboratory waste is essential
for a safe work environment.

Biohazardous waste should be treated and
disposed of promptly and not allowed to
accumulate
May be held temporarily, within lab or in
designated storage area prior to disposal
![Page 10: Disposal of Lmo and Related Waste](https://reader030.fdocuments.in/reader030/viewer/2022020417/563db811550346aa9a9040c4/html5/thumbnails/10.jpg)
Biohazardous waste boxes designated for pick-up
by service provider should be stored in a secure
area
Sheltered from inappropriate weather conditions
No access to unauthorized persons
Warning signs posted
![Page 11: Disposal of Lmo and Related Waste](https://reader030.fdocuments.in/reader030/viewer/2022020417/563db811550346aa9a9040c4/html5/thumbnails/11.jpg)
Storage enclosures must be clean after disposal
Inventory required
o Date (storage & removed)
o Laboratory generated from
o Laboratory supervisor’s name & contact number
![Page 12: Disposal of Lmo and Related Waste](https://reader030.fdocuments.in/reader030/viewer/2022020417/563db811550346aa9a9040c4/html5/thumbnails/12.jpg)
Biohazardous waste must be rendered harmless by
appropriate treatment
Waste should be treated as near the point of
origination as possible
At facility or by license service provider
![Page 13: Disposal of Lmo and Related Waste](https://reader030.fdocuments.in/reader030/viewer/2022020417/563db811550346aa9a9040c4/html5/thumbnails/13.jpg)
Autoclaving
Incineration
Dry heat
Chemical disinfection
![Page 14: Disposal of Lmo and Related Waste](https://reader030.fdocuments.in/reader030/viewer/2022020417/563db811550346aa9a9040c4/html5/thumbnails/14.jpg)
Review and establish standard conditions for
sterilization
o Type of materials
o Volume
o Contamination level
o Moisture content
![Page 15: Disposal of Lmo and Related Waste](https://reader030.fdocuments.in/reader030/viewer/2022020417/563db811550346aa9a9040c4/html5/thumbnails/15.jpg)
Written procedure for operation and testing of any
equipment used
Written procedure for preparation or chemical used
in treatment
Verification of efficiency of processes, showing
records to proof compliance to specified
performance standards
![Page 16: Disposal of Lmo and Related Waste](https://reader030.fdocuments.in/reader030/viewer/2022020417/563db811550346aa9a9040c4/html5/thumbnails/16.jpg)
All biohazardous materials and all contaminated
equipment or apparatus should be sterilized before
being washed, stored or discarded
Autoclaving the preferred method
Pathogenic organisms and infectious wastes
should be inactivated prior to leaving the facility
![Page 17: Disposal of Lmo and Related Waste](https://reader030.fdocuments.in/reader030/viewer/2022020417/563db811550346aa9a9040c4/html5/thumbnails/17.jpg)
Waste transported outside of facility (to autoclaved
or incinerator) should be in closed, leak-proof bags
or containers
All GM related waste should be double-contained
when transported outside the facility-sealed bags
placed in bin
