||Case study of solvent substitution in the cleaning of high-voltage circuit breakers

||This article presents a project undertaken in view of the substitution of the solvent currently used for removing silicone grease during the maintenance of high-voltage circuit breakers, namely a mixture of trichloroethylene, perchloroethylene and saturated hydrocarbons, which has been identified as the cause of mucous membrane irritation in several workers. Furthermore, trichloroethylene and perchloroethylene are known carcinogens. A nine-step systematic approach was adopted, consisting of supplier surveys, small-scale testing and more in-depth evaluations, leading to the selection of octamethyltrisiloxane. However, for reasons of cost, the enterprise finally selected the "Skysol" solvent (a mixture of saturated hydrocarbons and 3-methoxy-3-methyl-1-butanol).
