Hazardous Waste Collection


  1. Determine the disposal routes of the wastes before the procedure is to be conducted.
  2. Prepare the containers, container inventories and labels to accept the waste.
  3. Keep the amount of waste generated to a minimum quantity. Hazardous wastes charges are billed as the number of pounds shipped. Academic departments will not be directly billed for the wastes generated, but lack of cooperation or participation in the program could change this status. Excess waste charges deplete university funding that could be used elsewhere. Helpful Hints for minimizing wastes include:
    1. Substitute products or methods that generate less waste
    2. Adjust purchasing practices to purchase only the materials that will be used within 1-2 years.
    3. Downsize experiments or procedures to produce less waste.
    4. Control the materials that students bring into class for their own use.
    5. Do not accept materials from off-campus without prior approval from the Campus HMMC.
  4. Collect wastes as they are generated and transfer them to the proper labeled container.
  5. Update the container inventory after each addition of waste, if the waste does not have a single make-up.
  6. All containers must be kept closed except when adding wastes.
  7. Store all wastes in the satellite collection area in the laboratory.
  8. When the container is full, notify the hazardous waste coordinator for the department or the campus to remove the wastes. A completed waste inventory form must accompany the waste.


Collect the waste in glass, metal or plastic containers that are chemically compatible with the waste. Containers should be 5 gallons or less in size. The container must be labeled with:

  1. The words "HAZARDOUS WASTE"
  2. The primary hazard classes of the material.
  3. The contents: all solutes and solvents and known percentages. (This may be kept on an accompanying inventory sheet or card).
  4. The date of the first waste addition, and with each additional entry.
  5. The name of the responsible party for the waste and if necessary, the account number.

IMPORTANT NOTE: ALL containers of wastes must be closed except when adding wastes.
