Containers of chemicals destined for disposal must have appropriate labels. Chemicals in their original containers need only have their original labels affixed with “WASTE” clearly written on them. Chemicals in other containers must be clearly labeled as waste with the chemical name(s) of the chemicals. In the case of mixed waste, the constituents of the container must be listed, along with their approximate concentrations. An MSDS must be supplied if a trade name is used in place of a chemical name.
Logistically plastic containers are preferable to glass. However containers must be constructed of material compatible to the product they contain. The hazardous waste program will only accept securely capped containers in good condition compatible to the product they contain. Leaking containers or containers sealed with stoppers or parafilm are unacceptable.
The hazardous waste program does not return containers. If you wish to keep the container that your waste is stored in you will need to transfer it into a suitable waste container prior to sending it for disposal.
Containers should only be filled to 90% of their capacity to allow for vapor expansion. Solvent waste should be separated into two categories: Halogenated and Non Halogenated. Non Halogenated solvent containers should have the approximate water content marked on the label.
Where possible, waste should be stored in a location designated for this purpose. This will enable hazardous waste personnel to quickly find and collect your waste in the event of your absence.
