The exterior surfaces of the equipment should be free of dust, dirt, grease, oil, or fungus.
a. Remove dust and loose dirt with a clean cloth.
Adequate ventilation should be provided while using TRICHLORO-
TRIFLUOROETHANE. Prolonged breathing of vapor should be avoided.
The solvent should not be used near heat or open flame; the products

TRIFLUOROETHANE dissolves natural oils, prolonged contact with
