Solvents in the Workplace

The U.S. Environmental Protection Agency has released a new guidance document, entitled, Solvents in the Workplace – How to Determine If They Are Hazardous Waste [PDF].

Solvents are used in the workplace for many different purposes and once they are spent or left unused and destined to be disposed, making hazardous waste determinations can sometimes be a challenging task. This e-enterprise user-friendly guidance walks through a series of questions and answers that will help a facility determine if it may have generated a hazardous waste solvent. The guidance provides information to assist a facility in recyling or reusing its solvents which could reduce its waste management costs and the nation’s need for virgin materials. Also, at the end of the document, there are a number of questions the EPA has answered through the years involving hazardous waste solvents.
