DESCRIPTION
cxsxTRANSCRIPT
Types of waste generated from GM activities
Storage of LMO & related waste
Treatment of bio hazardous waste
Transport
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.
Contaminated liquid & solid materials
Consumables
Sharps
Waste
WHY?
o Personal safety
o Safety of co-workers, facility personnel & service providers
o The public
o The environment
Proper segregation
Storage
Treatment
Disposal
Non-hazardous waste
Non-hazardous biological waste
Solid biohazardous waste
Contaminated liquid waste
Broken glassware
Sharps
Puncture resistant
leak proof sharp
container
Heavy duty autoclavable begs
Heavy-duty leak
proof
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
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
Storage enclosures must be clean after disposal
Inventory required
o Date (storage & removed)
o Laboratory generated from
o Laboratory supervisor’s name & contact number
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
Autoclaving
Incineration
Dry heat
Chemical disinfection
Review and establish standard conditions for
sterilization
o Type of materials
o Volume
o Contamination level
o Moisture content
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
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
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
Containers display the biohazard sign
Consignment labeled
o Date
o Quantity
o Facility supervisor’s name & contact numbers
Facility should maintain record
o Date of treatment/disposal
o Method/conditions of treatment
o Name of persons/service provider performing treatment
Responsibility of all researchers to ensure the safe
and correct disposal of LMO and all wastes
produced in the course of their work
