Trichloroethylene is used in dry cleaning, in degreasing of metal objects, and in extraction processes, such as removal of caffeine from coffee or of fats and waxes from cotton and wool. The two major uses of trichloroethylene are as a solvent to remove grease from metal parts and as a chemical that is used to make other chemicals, especially the refrigerant, HFC-134a. (1) Trichloroethylene is also used as an extraction solvent for greases, oils, fats, waxes, and tars, a chemical intermediate in the production of other chemicals, and as a refrigerant. As a solvent or as a component of solvent blends trichloroethylene is used with adhesives, lubricants, paints, varnishes, paint strippers, pesticides, and cold metal cleaners. These The EPA has 2 years to finalize a rule to reduce the risks posed by the other 52 uses. The question is often asked by companies and organizations that have never used cleaners that contain the chemical but have heard good and bad things about using it on a consistent basis. hތ��n��_e.e��� $Ӳ�N *Q��\�ɵL�"rXo����YYT���{�P]]�����Ln�u�M%N>穤)�:�5mۣgp�����ScK�7W�rv���~��tw�n�����wO�����������w���8��~����W�{������x}�����������㓧Ww?��]|x����Nӓ�=O.��}ʻo_�_�S6vw��߿8\���8�w燱��������Ô�>Ϟ��6]|���ǖ��b����o>>������~���>L����\ċ�_�”����O�w�ݳo~x��oc��=���x8^��I��7������qs}�����ar����ݿ�^��X�=����w�^���ų�Á%~�� �/o��bLN/�_�}�������&�������H��-~>�� ��'wof7��T�%NI�R�e/m.EF��B_��|�e�N-L�籩�ц��>�f�e��ٸ�P�i�Ӝ��f���.B�K=RQ,��Tc���^N5�V���Tk���h9&k�����I�E3ȥD��d��1km�sS�I4�G.

Trichloroethylene (TCE) is primarily used as a solvent in the vapour-degreasing and cold-cleaning of fabricated metal parts, and in smaller amounts in dry-cleaning operations, paints and paint removers, and various household products. TCE does not occur naturally and is created by chemical synthesis. Tricholoroethylene(TCE) is a volatile organic compound mostly used to manufacture refrigerant chemicals in a closed system. This substance is used by professional workers (widespread uses), in formulation or re-packing, at industrial sites and in manufacturing. Instead, the Trump Administration has taken every opportunity to delay these bans – disregarding the intent of the nation’s reformed chemical safety law and putting the health of workers and the public at risk. It is nonflammable and has a sweet odor. Trichloroethylene breaks down very slowly in soil and water and is removed mostly through evaporation to air.
