Trichloroethylene

Trichloroethylene is a colorless, volatile liquid, primarily used in two ways - to make HFC chemicals, especially refrigerants, and as a solvent to remove grease from metal parts. Furthermore, it is used for spot removal in dry cleaning operations and is found in some aerosol cleaning products that can help in auto maintenance.

Trichloroethylene is an effective solvent for a variety of organic materials. It has also been used as a dry cleaning solvent. The major application of TCE has been as a degreaser for metal parts. TCE is used to flush jet engine's fuel system immediately before and after each test firing. The flushing procedure involved pumping TCE through the engine's fuel system and letting the solvent overflow for a period ranging from several seconds to 30–35 minutes, depending upon the engine.

TCE is also used in the manufacture of a range of fluorocarbon refrigerants such as 1,1,1,2-tetrafluoroethane more commonly known as HFC 134a. TCE was also used in industrial refrigeration applications due to its high heat transfer capabilities and its low temperature specification.

Handling Measures
and Precautions

DG Cargo. Proper human safety products such as splash goggles, lab coat, vapour respirator, NIOSH approved gloves and boots should be worn while handling and applying chemicals. Splashes on the skin should be washed off with water immediately. In case of splashing into the eyes, flush them with fresh water and obtain medical attention. Should not be injected.

Storage

Should be stored in original vented containers, away from heat, direct sunlight and combustibles. Store in a cool and dry place. Please refer label and SDS for details.
