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 RMSO 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.
