Standard Operating Procedure for Hazardous Waste

Chemical Waste-Internal

Creation Date: 10/09/2015  - S. Nephew
Revision Date:   07/07/2016 - S. Nephew


All hazardous waste shall be managed in accordance with campus, federal, state and local regulations.

Authority and Responsibility

The Science Programs and Facilities Support Professional (SPFSP) is responsible for:

  1. Providing faculty with the appropriate containers and labels for hazardous materials.
  2. Arranging removal and transportation of all hazardous materials.
  3. Providing spill kits for each laboratory.
  4. Coordinating pick up with EHS as needed, before 180 days.

Environmental Health and Safety (EHS) is responsible for:

  1. Maintaining regulatory compliance.
  2. Scheduling hazardous waste and regulated medical waste pickups.

Departments and Faculty are responsible for:

  1. The proper handling and storage of all hazardous materials outlined in this policy.
  2. Reading the SDS and characterizing their waste streams.  “no activity should begin unless a plan for the disposal of nonhazardous and hazardous waste has been formulated” [Prudent Practices in the Laboratory, 2011].
  3. Requesting the appropriate containers for their laboratory usage two weeks prior to the start of each semester.
  4. Relocating hazardous materials from hoods and/or bench top to the satellite waste accumulation area after the laboratory is finished for the week.

General Information

  1. A Satellite Accumulation Area (SAA) is the location at or near the generation of hazardous waste, where waste is picked up during routine pickups by the Science Programs and Facilities Support Professional (SPFSP).
    1. The SAA is a temporary collection site for any material that is determined to be chemical waste, is no longer of use, is old/outdated, or chemicals which are in bottles or containers that are in poor condition or have unreadable labels.
    2. The SAA cabinet doors will be labeled.  Ensure that chemicals are compatible before adding/mixing them in the waste collection bottle.   Label all contents on the outside of the collection bottle.
    3. The SAA will contain secondary containers, which you can then place your hazardous waste containers into, always being aware of chemical compatibility.  Since these materials may be stored for several weeks before transfer to the main storage area for commercial pickup and disposal, the possibility of unsafe reactions between different classes of chemicals must be accounted for.
  2. Hazardous waste should be removed from the hoods/benches/other areas after use and moved to the SAA by the producer of the waste (faculty, researcher, staff member).
  3. A Hazardous Waste Storage Area (HWSA) is the designated location on campus where the waste is transported from the SAA and temporarily stored until picked up by an off-site collection agency.  Our HWSA is located at Hudson Main Room 100.
  4. All waste will be directly transported from the SAA to the HWSA in Hudson Main Room 100 via an approved cart by the SPFSP, or a designated employee of that office.

Pre-Pick Up Instructions

  1. Prior to the start of the semester, email the SPFSP for needed containers for hazardous waste accumulation. Provide information regarding hazardous waste to be generated and estimated amounts.  Our practice will be to collect waste “by experiment,” which should help to eliminate issues with incompatibility and should create smaller volumes of waste to be disposed.  The smallest size of waste container appropriate for the experiment should be selected. 
  2. To dispose of empty chemical containers, follow the guidelines for rendering your containers “RCRA empty”.  For acutely hazardous waste, triple rinse the container with the appropriate solvent and collect the rinsate as hazardous waste.  For further information on RCRA empty and acutely hazardous waste, see
  3. Deface the labels on the container and record the bar code number.  Dispose of the glass bottles in glass waste bins and other containers in the regular trash.  Email the SPFSP the Vertere bar codes and chemical information. It is also permissible to put the empty bottles in the satellite accumulation area and contact the SPFSP when the SAA is nearing capacity.
  4. Email when you have full containers that need to be picked up.  Be sure the waste is in approved containers and labeled with the exact contents. Include the amounts (volumes, percentages, concentrations) of chemicals when possible.
  5. Pick-ups are handled at the discretion of the SPFSP.
  6. Make arrangements for pick up with the SPFSP.
    1. The SPFSP will document date of pickup and notify the generator via email.
