CoLLect

  • CoLLect all of your hazardous chemical wastes and submit a chemical pick-up request form to EH&S for proper disposal.  Please consult with EH&S if you are unsure if your chemical waste is Hazardous Waste. http://vesta.cumc.columbia.edu/ehs/wastepickup/
  • Evaluate your chemical inventory periodically and coLLect chemicals for disposal that are unwanted, expired or have no intended use.
  • DO NOT- Dispose of Hazardous Waste inappropriately or prior to determining its hazards.  Hazardous Waste must not be poured down the drail
Label
  • Affix a Hazardous Waste Label to the container as soon as you start collecting waste.
  • List all of the components of the Waste on the Label.
  • DO NOT - Use chemical formulae or abbreviations on Hazardous Waste Labels.

Lid

  • Keep Hazardous Waste containers closed at all times, except when actively adding or removing waste.
  • Use a closeable Lid that will prevent the Hazardous Waste from spilling should the container be knocked over.
  • DO NOT - Leave a funnel in a Hazardous Waste container.

Locate

  • Locate Hazardous Waste containers at or near the point of the Hazardous Waste’s generation (a.k.a. Satellite Accumulation Area).
  • DO NOT - Locate Hazardous Waste containers outside of the room in which the waste was generated.

Leaks

  • Inspect Satellite Accumulation Areas weekly for Leaks.
  • DO NOT - Allow Leaking containers to remain in Satellite Accumulation Areas. Contact EH&S upon discovering the leak.

When a waste container is 90% full, submit a Chemical Waste Pick-up Request Form by visiting:http://vesta.cumc.columbia.edu/ehs/wastepickup/
