Practical considerations for establishing phase-out dates for CFC-113 and 1,1,1-trichloroethane when used as industrial solvents

This paper presents information, examples, and opinions leading to the authors conclusions on practical dates for phase-out of 1,1,2-trichloro-1,1,2-trifluoroethane (CFC-113) and 1,1,1 trichloroethane (mythyl chloroform) when used as industrial solvents and cleaners. The dates refer to an expected Amendment to the Montreal Protocol. The paper is based on information obtained from the Department of Energy, the Air Force, from author participation on the United Nations Environmental Panel Solvents, Coatings, and Adhesives Technical Options Committee, and from recent publications. The paper informs the reader of impending legislature, possible impacts of that legislature, and of less obvious requirements which will impact cost of compliance and will extend the time required to reach compliance. The purpose of the paper is show users of CFC-113 and 1,1,1-trichloroethane the legal and moral necessity of rapid phase-out of those chemicals, point the user in the right direction for long-term solutions, and urge lawmakers to balance the need for action with the realities of the technical and economic situation.
