Packaging and Labeling Process
Disposal of Biohazard Waste
For biohazard wastes that can be autoclaved or treated, the individual generator (researcher, department) shall:
- Render innocuous all infectious waste (except sharps and sharps containers, animal carcasses and contaminated bedding) through autoclaving or treatment with bleach (5% sodium hypochlorite solution) prior to discarding as regular trash.
- Any autoclaved or treated waste suitable for disposal as regular trash shall be placed in a dark plastic trash bag PRIOR to disposal. Disposal of dark bag waste into a solid waste dumpster is the responsibility of Building Services or the researcher or department (during breaks and weekends). Building Service Personnel shall not handle waste in red biohazard bags.
For biohazard wastes that cannot be autoclaved or treated, the individual generator (researcher, department) shall segregate and label the waste prior to pick-up by RMS as follows:
- All waste containers shall be marked with the P.I. or supervisor’s last name, room/lab number and department.
- Used and unused sharps shall be placed in a sharps container with a biohazard symbol. All sharps containers ready for disposal need to be completely sealed so nothing is protruding from the container and the lid and all safety tabs are fully engaged.
- Contaminated animal carcasses shall be placed in red bags, frozen and secured by tying off the bag.
Disposal of Chemical Waste
Preparing for pickup by RMS
- RMS provides 2.5 and 5 gallon carboys for solvent wastes and 5 gallon buckets for solid chemical wastes (ethidium bromide, silica gel, contaminated weigh boats, filter paper, etc.). Contact RMS at 1-5037.
- Chemical Liquid and Solid Waste: All liquid waste containers require a Chemical Discard Tag properly completed and attached to the container before RMS arrives. The container shall be leak/spill proof with an approved lid (parafilm, plastic wrap, aluminum foil, etc., are not approved lids).
- Chemical Discard Tags: Chemical Discard Tags shall be completed with the following information:
- Department Name
- Room/lab number
- Enter non-abbreviated, non-trade name chemical description
- Percentage of each chemical, make sure it totals to 100%
- Quantity in grams or liters
- Signature of the person filling out the tag
- The PI name printed legibly
- Tags have a peel off adhesive back to attach to containers. Tags shall be placed on the container so container labeling is not covered. If the tag wraps completely around the container and/or itself, attach the tag to the container by a rubber band or other method. The top white “office” copy and carbon sheets shall remain on the container. The middle yellow copy is the lab’s copy. RMS personnel will remove the carbon sheets, top white, and middle yellow copies when the waste is picked up. The yellow copy will be left in the lab’s chemical waste area.
Disposal of Radioactive Waste
All radioactive waste containers shall have radioactive symbols, the orange sticker (corresponding to the respective paperwork) attached and the paperwork completed before RMS arrives. If the waste is in a bag, it shall be closed.
- Radioactive Waste Pickup Form – The following information is required:
- Responsible Investigator last name printed legibly
- Department Name
- Name of person completing the form printed legibly
- Phone number
- Number of waste containers for the corresponding waste category
- Radionuclide(s), their activities, and units of activity circled
- Amount of solutes in grams, solvents in %/vol, type of cocktail, percentage of glass, metal, paper, plastic, or components in aqueous solution.
- Numbered orange sticker corresponding to form’s pickup number
- The Radioactive Waste Pickup form has a pickup number in the upper right corner and orange stickers with that pickup number printed on them. Orange stickers shall be attached to radioactive waste containers listed on the Radioactive Waste Pickup form
