Package sharps, glass and pipettes in a semirigid tertiary container
labeled with its contents. This container is placed in double
bags with other dry waste. Double bag waste in clear bags of at
least 3 mil thickness*, (18" by 24" size 3 mil bags are available
through Lab Safety Supply item 9A-34530 from 1999 catalogue.)
Take necessary precautions to prevent external contamination
of the outer bag. Twist and tape each bag closed.
Fill out the tag completely, include your license number. Express
activity in milli or micro curies.

Do not tie bags closed with only tag wires or rubber bands.
Do not place biohazardous or other biological material with other
Do not place lead shielding materials into waste.
If you already have a supply of bags of less than 3 mil thickness,
they can be used in conjunction with a 3 mil bag (use one of each)
until your supply of thin bags is expended.
Separate waste by isotope
Insure that the lids are tightly closed on all containers during
Transfer waste in a secondary container of sufficient volume
to contain the waste in the event of a leak.
Completely fill out the radiation tag including LA# and all chemical
components in percent by volume including water. If hazardous
chemicals are present then a hazardous waste tag is also required.
Minimize hazardous mixed waste.
Inspect containers for holes or cracks before use.
Call the isotope desk to schedule the return of waste jugs.
Liquid Scintillation Fluid
Use liquid waste tags for scintillation vials. Double bag vials
in their original racks if possible.
Insure that the caps are tightly secured on the vials.
Write the brand name and/or product name of the cocktail on the
Do not fill containers to more then 75% capacity.
Do not use containers larger then 10 liters.
Do not reuse reagent bottles unless chemical compatibility requires
