Waste Disposal Procedures

To ensure compliance with OSHA, EPA, and Louisiana Department of Environmental Quality regulations, follow the guidelines for waste disposal below.  No chemical, radiological or pharmaceutical waste materials shall be discarded via the sanitary sewer system.  Liquid biological materials which are treated in accordance with the below Biological Waste procedures may be discarded through the sink.  For additional assistance or questions call 504-568-6585 or email safety@lsuhsc.edu.

Biological Waste

Biological waste (including gloves and rDNA materials) must be placed inside of a bio-hazard plastic red liner bag, which is then placed within a bio-hazard cardboard box.  Environmental Health and Safety provides bio-hazard boxes.  Researchers can pick supplies up on the second floor of the Medical Education Building at the custodial department, at the Clinical Science Research Building, School of Dentistry Annex Building shipping and receiving room (near the loading dock).

Boxes must be packed with care, paying attention to weight (less than 30 lbs.) and volume (less than 4/5th full).  The box must be taped to prevent accidental opening.  Each box should be labeled with the following information legible and visibly printed: BUILDING NAME, ROOM NUMBER, RESEARCHER’S NAME and PHONE NUMBER.  Once the box properly secured, place in the hall corridor against the wall for daily pickup by Environmental Health and Safety personnel.  Open bio-boxes are not to be stored in common areas such as hallways, etc.

Pathology wastes (including animals used for research) must be disposed via Animal Care pathology containers or be labeled for segregation. Label boxes legibly and visibly printing with PATHOLOGY WASTE along with the ROOM NUMBER and RESEARCHER’S NAME.   

Any waste containing viable cultures of microorganisms must be autoclaved.  Potentially infectious biohazard liquid waste must be autoclaved or inactivated by an appropriate amount of disinfectant.  After disinfection, liquid wastes rendered noninfectious may be disposed of by the sanitary sewer system.  Small quantities (less than 25 mL) of liquid biohazardous wastes that are BSL-1 or BSL-2 may be sealed in plastic leak-proof labware and disposed of in a biohazard box.  If you need help in determining if your waste needs to be autoclaved, contact the Biosafety Officer, Lauren Gonzalez, at lgonz8@lsuhsc.edu or 504-568-6586.

SHARPS containers are not to be overfilled, and must close without any protrusions.  When full, snap the lid shut tape the container closed, and place the container in a bio-hazard waste box.  SHARPS containers are available for purchase through LSUHSC Medical Stores.

Glass Waste

Place glass waste in a glass waste box with a plastic liner. To request liners and cardboard boxes to use for glass waste, use the On-Line service request work order system. While inputting your request, please use the "short description" text box to inform Environmental Health and Safety of the location where you would like these supplies to be delivered. All glass should be dry, with no toxic residue.

Boxes should be packed with care, paying attention to weight (less than 15 lbs) and volume (less than 4/5th full). The box should be taped to prevent accidental opening. The box should have the researcher's name, department, building and room number, phone number, and "GLASS WASTE" should be visible and legible. Once properly labeled and closed, the box should be placed in the corridor along the wall for the custodians to pick up.

Pharmaceuticals and Controlled Substances

Pharmaceuticals used for research will be picked up as hazardous chemical waste (described above). Use the On-Line service request work order system.

Controlled substances are chemicals scheduled with the DEA. Use the proper reverse-distribution channels to return unused drugs to the appropriate authorities.

Radiation Waste

Radiation liquid containers and solid dry waste cardboard boxes are picked up every Tuesday. Request pickup using the On-Line service request work order system. The permit holders' name, telephone number, building and room number, and the type and amount of liquid and/or dry waste to be picked up should be entered.

Radiation waste record forms pdficon_small  are available from Environmental Health and Safety (568-6585) and should be filled out prior to pickup and taped on the appropriate container. Quantities should be listed in Micro-curies or Milli-curies. While inputting your request for pickup, please use the "short description" text box to inform Environmental Health and Safety if you would also like empty cardboard boxes, plastic liners and plastic 1 or 5 gal containers delivered for future use.

Mixed Waste

The term “mixed waste” refers to liquid or solid wastes that contain both radioisotopes and one or more hazardous chemicals meeting the EPA’s definition of a hazardous waste. It also includes solid, radioactive oxidizers such as thorium nitrate and uranium nitrate.

Labelling for mixed waste needs to include chemical entities along with the Radiation waste record formspdficon_small. Request pickup as with chemical or radioactive waste.

Universal Waste

Universal waste includes hazardous wastes that are commonly encountered, such as batteries, light bulbs, electronics, and mercury-containing products. Environmental Health and Safety will pick up batteries and mercury-containing products such as thermometers. Use the On-Line service request work order system for these items.  Waste lamps and bulbs are collected for disposal by a Univeristy contractor.  In the event of a broken lamp or blub, please follow the clean-up procedures.pdficon_small

Computers, printers, and monitors must be returned to Asset Management. Prior to returning a computer, the hard drive must be wiped by Computer Services or your department’s IT specialist. Contact Inventory Control at (504) 568-6280 or email to arrange the return of the used electronics.
