Chemicals cannot be poured down the drain. We are served by the Baton Rouge city sewer system, and introduction of chemicals into the drains can result in unsafe conditions for campus personnel and even personnel off campus in neighboring communities. Do not dispose of hazardous waste in the trash or evaporate in fume hoods. If you have a question about what can be placed in the drains, please call our office at 8-5640.
All hazardous waste must be disposed of through the EHS department according to the following procedures.
Container and Storage Requirements
- Chemicals must be placed in a compatible, sealed container that shows no signs of leakage. Chemical containers must be in good condition. Bottles with broken caps or stoppers will not be collected. Waste containers will not be returned to the generators unless arrangements have been made with this department prior to the pick-up.
- Containers should be full, but not overflowing, leave room for expansion.
- Waste must be stored according to chemical compatibility/hazard class.
- Use secondary containment for all liquids when in storage. Do not accumulate more than 55 gallons of waste in the laboratory.
- Keep containers closed at all times, except when adding or removing waste. Do not leave funnels in containers unless they have a tightly sealed lid.
Waste Label Requirements
- Chemical waste must be labeled with a Hazardous Waste Label. Blank waste labels can be accessed here. Customized labels can be created using EHSA.
- Unused or unopened chemicals, or original bottles containing remaining original material do not require additional labeling. Original factory label is sufficient.
- All information requested on the waste label must be properly completed. Improperly completed labels will be returned.
- Use proper chemical names for the components of the waste. DO NOT USE FORMULAS, TRADE NAMES OR ABBREVIATIONS.
- List the percentages of ALL components in the waste.
Scheduling Waste Pickups
- After properly filling out the waste label, tape/adhere to the container. You may use an ESHA printed label or the hard copy label.
- When ready for waste pick up; complete an on-line Waste Disposal Request using the EHSA system.
- Waste should be picked up within 10 working days.
Additional Waste Requirements
Peroxide forming compounds (e.g.; diethyl ether, 1,4-dioxane, tetrahydrofuran) must have a date of receipt and opening written on the container. The maximum storage period must not have expired. This is generally one year.
Unknown waste are handled on a case by case basis. Avoid generating Unknowns by keeping legible labels on the waste you produce and disposing of all waste in a timely manner. Please refer the Unknown Chemical Guidelines document.
Explosive waste is handled on a case by case basis. Avoid generating this waste by diligently observing the expiration dates on chemical labels.
EHS accepts all batteries, used oil, and certain fluorescent light bulbs for recycle. They can be picked up during regular hazardous waste pickups. Fluorescent Bulb Disposal Guidelines
Biological waste is also handled by the EH&S department. Red bags and boxes are available. Puncture proof containers must be purchased by the department. Biological Waste Disposal Guidelines
Radioactive waste is handled by Radiation Safety Office.
Contained gas (cylinders, lecture bottles, etc.) are not normally picked up, arrangements should be made with the supplier for the removal of the containers at the time of purchase. Contact University stores initially for return option.
Do not dispose of hazardous waste in the trash, down drains, or evaporate in fume hoods. Elementary neutralization is permitted as part of a written protocol for experiment/research.
Empty glass chemical containers may be placed in a broken glass box or other sturdy cardboard box, properly sealed, and carried by lab employees to the trash dumpster. Sharp plastic ware must also be placed in a broken glass box or sturdy cardboard box, properly sealed and carried by lab employees to dumpster. Sharps must be placed in puncture proof containers. Non contaminated sharps can be sealed and placed in the municipal trash, contaminated sharps can be sealed and picked up by EHS. Certain empty plastic containers may be suitable for the recycle dumpster.
Maintain emergency equipment (eyewash, showers, etc.) and know what to do in the event of a chemical spill, fire, or explosion. (Fire and Emergency Procedures)
Use pollution prevention techniques to reduce the amount of hazardous waste you generate. (i.e. waste minimization, material substitution, etc.). Click here to learn more.
Insure the documentation of initial (prior to lab use) and annual training/instruction of laboratory employees on proper waste procedures. Training records shall be kept by the department.
