Trichloroethane vapor, when used in poorly ventilated and confined spaces may result in
damage to the lungs, eyes, and skin, and is toxic if taken internally. Avoid any prolonged
or repeated breathing of the vapor or contact with the skin. In addition, the evaporative
products resulting in the heating of trichloroethane are more toxic than the unheated
liquid, so caution must be taken not to use trichloroethane on any heated surfaces.
(1) Clean the area adjacent to the rupture to ensure it is free of oil, grease, dirt, paint, and other
foreign matter. If grease or oil is present, use an approved cleaning solution such as Stoddard or
trichloroethane (methyl chloroform). If neither of these solvents is available, scrape and wipe free. When a
clean surface is obtained, the surface may be further abraded for better adhesion using the abrasive cloth
furnished with the kit.
