Title Case study of solvent substitution in the cleaning of high-voltage circuit breakers
Original title Etude de cas de substitution de solvant pour le nettoyage de disjoncteurs haute tension [in French]
Bibliographic information Sep. 2008, Vol. 24, No.3, p.30-36. 50 ref.
Abstract 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).
