The UW Waste Disposal Program specifies how hazardous laboratory waste is to be collected, segregated, stored, and transported.
All organic solvents are to be placed in the appropriate waste solvent carboy.
Square carboys are for halogenated solvents, such as trichloroethane or EnSolv. Round carboys are for nonhalogenated solvents, such as ethanol or acetone. Acids and bases are to be neutralized and diluted prior to disposal down a laboratory sink. Refer to the UW Chemical Safety and Disposal Guide . Base and acid neutralizers are located in the SRC Chemical Room and in the PSL Vacuum Test Area.
