Identifying a material as a hazardous waste requires a certain degree of professional knowledge about the processes that generate hazardous waste, and the chemical and physical characteristics of the waste. Most handlers of hazardous waste will have the knowledge and experience needed to identify hazardous waste correctly. However, in some instances it is uncertain whether a material is a hazardous waste or not. It is important that a consistent process is followed when determining whether a waste is hazardous. We have put together a Hazardous Waste Identification Flowchart for you to follow when determining whether a waste is hazardous. Information on how to apply the criteria outlined in the flowchart can be found in the following sections of these Guidelines.
