Hazardous Waste Disposal
Safety Instruction Number:8
Last Update:Tue, 02/02/2016
- Hazardous waste generated at Oregon State University must be disposed of through a system managed by Environmental Health & Safety (EH&S).
- The designation "hazardous" refers to any substance that is
OR is a listed waste (K, F, P, or U listed)
- It does not refer to material that is only radioactive or biohazardous.
- Hazardous waste disposal is funded for University units.
- Departments are encouraged to employ waste reduction procedures to limit university costs.
- If there are questions or unusual circumstances, please contact EH&S at 7-2273 for assistance.
- Prior to disposal of any chemical waste, the waste generator must perform an official hazardous waste determination to see if the waste is hazardous.
- Note: The hazardous waste determination must be conducted by the person generating the waste at or near the point of generation.
- A short list of non-hazardous chemicals can be found on the EH&S web site; all others should be considered hazardous until the determination has been made.
- Hazardous waste is incinerated, at off-site locations, whenever possible. Departments are encouraged to employ waste reduction procedures to limit costs. Use these guidelines to prepare and request disposal of hazardous chemical waste.
- Collect each waste in a NON-LEAKING container; match size to amount of waste. Use containers chemicals were received in
- Liquid containers must be less than 5 gallons and 45 pounds (about 3-4 gallons of typical halogenated solvent).
- Reusable solvent waste containers and single use containers for aqueous/corrosive/metals and misc wastes are avaialble from EH&S.
- All containers must have non-leaking, tight fitting lids that are not cracked, broken, or chemically damaged.
- Paper or cardboard containers should be put into sealed plastic bags.
- Containers should be labeled as soon as waste is put into them, and must be capped at all times when not actively adding waste.
- Chemicals in original non-leaking containers with manufacturer's label will be accepted with a single hazardous waste label for all containers grouped together by hazard.
- All other wastes require a hazardous waste label, available from EH&S and from the EHS website, completed and attached to each waste container.
- Do not cover existing labels or markings.
- Solvent and aqueous containers provided by EHS should have the correct label pre-attached.
- Fill out the label with:
- Your name, building, room number, and contact info.
- Identification of contents, including total weight or volume and percent ranges for all constituents, and hazardous waste category.
- Do NOT pack and seal materials in boxes.
- Waste containers will be examined, and EH&S will then pack and segregate waste according to compatibility.
- Boxes should be sealable and sturdy enough to transport the material.
- Boxes exceeding 45 pounds or 18 inches on a side cannot be safely handled by one person, and will not be picked up.
- To request waste pickup, use the hazardous waste web form.
- YOU are responsible for proper containers and labels.
- Do NOT package waste in boxes.
- All containers must be less than 45 pounds.
