New or unused organic solvents no longer needed should be submitted to chemical safety for pickup as surplus chemicals. Where possible, quality chemicals will be included in our Chemical Redistribution Program.
Used organic solvents are a Hazardous Waste and must be managed by chemical safety. A hazardous waste must be collected in a closable, compatible container, labeled with the phrase “Hazardous Waste” and the primary hazard (typically “Flammable”). Volumes no more than a gallon are best collected in old solvent bottles. For collecting larger volumes, you should request a solvent carboy.
What is a solvent carboy?
A carboy is a 5 gallon (20 liter), square, plastic jug that is given out by the Office of Chemical Safety for use as a collection container for used lab solvents.
How do I get a solvent carboy?
Fill out the required information and how many solvent carboys for drop off that you’d like on the Chemical Disposal/Surplus Pickup Request Form.
What color/type of solvent carboy do I need?
The carboys for non-halogenated waste solvents are white. White carboys are used for the collection of waste solvents such as alcohols, acetone, acetonitrile, toluene, etc. suitable for fuel blending. Follow the Guidelines For Using Carboys.
The carboys for halogenated waste solvents are yellow/orange. Yellow/orange carboys are used for the collection of halogenated solvents such as chloroform, dichloromethane (methylene chloride), Freon 113 (trichlorotrifluoroethane) and trichloroethylene. Follow the Guidelines For Using Carboys.
What do I need to do when my solvent carboy is full?
1. Use the Chemical Disposal/Surplus Pickup Request Form. Fill out the required information indicating which solvent carboys you want picked up and/or swapped out for empty ones.
2. Fill out the Chemical Inventory of Waste Flammable Solvents (Carboys) Form for each full carboy and keep them with the carboys for pick-up.
Do I have to use a solvent carboy?
No! If your lab does not generate enough waste to fill a 20 L carboy in a timely fashion, does not have space for a carboy, your building is limited by MAQ concerns, or your waste is not compatible with common organic solvents, you do not have to use a carboy. Simply collect your material in a sealed, compatible, and disposable container (empty solvent bottles are ideal). Label the bottle as “Hazardous Waste, Flammable” along with a description of the actual contents (e.g. 20% ethyl acetate in hexane). You may use this label that is designed to be printed on Avery Label #5168.When the container is full, submit a request via the Chemical Disposal/Surplus Pickup Request Form for the container to be picked up.
