Special Concerns


Employees who generate hazardous waste must maintain and control their hazardous waste accumulation areas. Special concerns for hazardous waste include the following:

  • Unneeded chemicals that are to be discarded must be handled and managed as hazardous waste.
  • Unknown chemical waste will be picked up by the EHSRM however the University will incur additional charges for the chemical analysis to determine the proper disposal method. If possible identify unkowns at the point of generation.
  • Gas cylinders (including lecture bottles) are extremely difficult to discard. They should be returned to the manufacturer or distributor whenever possible. Cylinders that cannot be returned should be tagged as hazardous waste as soon as possible.
  • Photographic chemicals containing silver may not be placed in the sanitary sewer. They must be disposed of as hazardous waste.
  • Developer, paint waste, oil, paint rinse water, detergents, degreasers, and any other chemical cannot be disposed of in the sanitary sewer or storm sewer. These are prohibited for disposal by the City’s Industrial Waste Water Permit issued to the University.
