WARNING
USE OF CLEANING SOLVENT
Fumes of TRICHLOROTRIFLUOROETHANE are poisonous. Provide adequate
ventilation whenever you use TRICHLOROTRIFLUOROETHANE. Do not use
solvent near heat or open flame. TRICHLOROTRIFLUOROETHANE will not burn,
but heat changes the gas into poisonous, irritating fumes. DO NOT breathe the
fumes or vapors. TRICHLOROTRIFLUOROETHANE dissolves natural skin oils. DO
NOT get the solvent on your skin. Use gloves, sleeves and an apron which the
solvent cannot penetrate. If the solvent is taken internally, see a doctor
immediately.
