78 THE ANALYSIS AND TESTING OF NON-OZONE DEPLETING SUBSTANCES USED IN THE MACHINE REPAIR INDUSTRY Carol N. Carey, Manager Environmental Programs General Electric Company Schenectady, New York 12345 Simeon J. Komisar, Professor Nicholas L. Clesceri, Professor Department of Civil and Environmental Engineering Rensselaer Polytechnic Institute Troy, New York 12180-3590 INTRODUCTION With the passing of the Montreal Protocol and growing concern over the depletion of the ozone layer, increased attention has been focused on chlorofluorocarbons (CFCs) and other ozone depleting substances (ODSs). Industry has long relied on these substances to manufacture products and service customers' needs. Research and testing of other chemicals has intensified since the passing of these regulations in order to find acceptable substitutes that will meet the specific needs of industry and yet will not be detrimental to the environment. In the machine repair industry, ODSs are extensively used in switchgear cleaning. The superlative quality of many CFCs is their cleaning ability, their short drying time, high flashpoint, and low conductivity. NonCFC substitutes often do not perform as well as their CFC counterparts. In many cases, product specifications require the use of a certain chemical to ensure product performance and product stability. Therefore, to find nonODS replacements is a difficult challenge. Products must be tested and evaluated, employees must be educated to the fact that nonODS products are not going to perform in the same way as ODSs, and in some cases totally new application techniques and drying methods must be used. This study researched nonODS substitutes for switchgear cleaning in the machine repair business. Preliminary information was obtained through a survey of field experts at 67 General Electric service centers, a literature search, and vendor discussions. After initial selection, nonODS candidates were field tested and evaluated based on specific performance characteristics. These parameters were: cleaning ability, flashpoint, drying time, residue, dielectric strength, and cost. Field quality control experts performed the tests. A ranking system was established for each parameter based on a 1-5 scale, ranging from lowest to highest, respectively. Results from the field tests identified which nonODS products were selected for continued use in the machine repair business. ODS products were then banned from use in switchgear cleaning work at the General Electric service center facilities. Study results were shared with other businesses involved in similar industrial applications that were still using ODSs.
