Hazardous Waste Requirements

Below is a list of labeling requirements for Hazardous Waste.

1. Hazardous Waste: The term "Hazardous Waste" must be on the label.
2. Hazardous Material Name and Concentration: Be as descriptive as possible when identifying the material name and concentration of the waste. "Unknown" is not an acceptable material name and will not be collected by EH&S.
3. Quantity: Indicate the quantity of the material and check the appropriate unit of measure. Avoid writing in ambiguous units of measure like 3 boxes or 2 bags as they do not quantify the amount of waste accurately. The quantity is the size of the container, not how much is in the container. (e.g. 1 ounce of waste in a 1 gallon container should be listed as 1 gallon)
4. CA Waste No.: On the reverse of the White (middle) sheet, select the California Waste Number that best describes the waste.
5. Waste Class: On the reverse of the Gold (last) sheet, select the DOT Waste Class that best describes the material. If multiple classes apply, take the lowest number. (e.g. a class 3 and class 8 should be reflected as class 3 since Flammable liquid is a higher priority than Corrosive Material)
6. Form: Indicate the physical state of the waste. If any standing liquid, choose liquid. State should be relative to Standard Temperature and Pressure (STP)
7. Initial Accumulation Date: This is the date you began filling the waste container. This date starts a 90-day clock by which time the waste must be shipped off campus.
8. Final Accumulation Date: This is the date you completed filling the waste container. Ideally, when the final accumulation date is added, you should notify EH&S for a waste pick-up. The final accumulation date should generally be within 45 days of the initial accumulation date to ensure that EH&S has ample time to arrange for transport off campus within that 90-day window.
