3 Waste Definition Can the material be used by someone else? Is the material:Intended to be discarded ( i.e. the materialis “abandoned,” “recycled” or inherently“waste-like”) EPA views old chemicals thathave not been used in years and which areunlikely to be used in the foreseeable futureas waste.Give the material to anotherauthorized laboratory or user.If your material is not a WASTE,then it is not a Hazardous Waste.Waste DefinitionSTARTYESNOMaterial meets the definition of WASTEContinue on Master Flowchart
