TRICHLOROTRIFLUOROETHANE
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. TRICHLOROTRI- FLUOROETHANE 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, consult a physician immediately.
