waste is defined at LBNL as any recognizable human or animal body part and
tissue. The most common pathological waste found at LBNL is an animal

Pathological waste pickup containers are supplied by LBNLs
medical waste subcontractor (Figure 4-1). They are usually red, and are
prelabeled with the biohazard symbol and the words Pathological Waste.
containers must be lined with a red biohazard bag before depositing

4.3 Pathological Waste Disposal Procedures
following section describes the procedures that must be followed when disposing
of pathological waste.
Wear the appropriate PPE for handling
pathological waste (e.g., lab coat, gloves, safety glasses).
Deposit the pathological waste into a
biohazardous waste bag. Seal the biohazard bag closed (tape, rubber band, etc.) Red biohazard bags are to be used for pathology waste in areas where the laboratory
waste is deposited into
lined with red biohazard bags. Clear biohazard bags are to be used for pathology waste in areas where the laboratory
waste is deposited into containers lined with clear biohazard bags.
Label the outside of the bag with the
generator's name and extension, and the date the bag was sealed.
Store the bagged waste in a freezer. This
helps to minimize odors.
The morning of the pickup, transfer the
waste into a pathological waste pickup container.
Fill out the Medical Waste Accumulation Log
Wash your hands after removing your
4.4 Pathological Waste Contaminated with
waste that is contaminated with radioactive material (e.g., animal carcasses
labeled with tritium) is not medical waste. It is regulated as
radioactive waste. This waste must not be put into the pathological
waste containers. Refer to LBNL/PUB-3092, Guidelines
for Generators to Meet HWHF Acceptance Requirements, for
proper disposal of these wastes, or contact your Generator Assistant.
4.5 Pathology Waste from a Radioactive Materials
waste originating from an RMA must be below minimum detection levels for
radioactivity. By signing the Medical Waste Accumulation Log, the generator is
certifying that there is no detectable radioactivity in the waste. If you are
unsure whether there is radioactive contamination in your medical/biohazardous
waste, please contact your Radiation Control Technician.
