*Do this check before each deployment to a mission location. This will permit any existing problems to be corrected
before the mission starts. The check does not need to be done again until redeployment.
Warning: Adequate ventilation should be provided while using TRICHLOROTRIFLUOROETHANE. Prolonged breathing
of vapor should be avoided. The solvent should not be used near heat or open flame; the products of
decomposition are toxic and irritating. Since TRICHLOROTRIFLUOROETHANE dissolves natural oils,
prolonged contact with skin should be avoided.
When necessary, use gloves which the solvent cannot
penetrate. If the solvent is taken internally, consult a physician immediately.
Use a dry, clean, lint-free cloth or brush to remove dust or dirt.
If necessary, moisten the cloth or brush with trichlorotrifluoroethane.
After cleaning, wipe dry with a clean cloth.
