Chemical Waste Information

Chemical Waste is disposed of by the Environment, Health & Safety office.  Certain hazardous chemicals are regulated by the Environmental Protection Agency (EPA) and are deemed "Hazardous Waste".  Hazardous Waste is defined as chemical material that can no longer be used for its intended purpose and is known to be harmful or potentially harmful to human health or to the environment. For more detailed information please refer to the Hazardous/Non-Hazardous waste site.

Researchers and Staff that generate hazardous chemical wastes are allowed to have an area to collect hazardous waste in containers. These designated areas are called
"Satellite Accumulation Areas."

Hazardous Waste Label

Preparation of Waste for Disposal:

All waste should be segregated, stored, and labeled appropriately in your satellite accumulation area.  The previous links should provide adequate instructions on how to accomplish this preparation.

Method of Disposal:

Once you have filled a "hazardous waste" container or have a chemical that you no longer wish to keep, you need to fill out the Chemical Pick-Up Request form.  This form will ask who you are, what room and building the chemicals are in,  what chemicals you need to dispose of, in what size containers, and how many of each container. Refer to the instructions on how to fill out the chemical pick up form.

If you have any special instructions like where the materials are located within the room, special instructions on when the pick-up should occur, or if you need more blank Hazardous waste labels or certain empty containers that EHS supplies, you can enter this information in the comments section. 

The form will be submitted electronically to several members of EHS and someone will come to get the materials - usually within hours, but within up to three working days.

In most cases, even for large amounts of chemicals, you will be instructed to follow the same instructions as for small amounts.  In very rare cases, for example if an entire lab filled with chemicals is being cleaned out, EHS can provide special assistance.  Please contact the EHS office to discuss these special cases.

Examples of items that are disposed of as Chemical Waste:

  • Acids, Bases, Flammable Materials, Organic Solvents, Toxic Materials, Pesticides, Oxidizers, Buffers, Salts, and other laboratory chemicals
  • Drugs (DEA regulated and non-DEA regulated)
