New Study on DCM

October 2016

Together with HSIA, ECSA supported a study to clarify the mode of action of cancer formation for methylene chloride (DCM). A publication is expected soon in a peer reviewed scientific journal. The outcome of the study shows thatbelow a threshold there is no risk on cancer formation related to DCM.


Use of Perchloroethylene safe in Germany

October 2016

The German federal authorities (LAS) published a comprehensive guidance on the safe use of PER in dry-cleaning based on German regulations (2. BImSchV being in place since 1993). The  recent exposure study of the LAS (2015) proved that use of PER is safe and showed that following regulations results in very low exposures well below the current German OEL. ECSA supported the English translation of this Guidance.

French Dry-Cleaning shops on fire

October 2016

Dry-cleaners in France have been forced to use alternative (flammable) solvents instead of PER (arête 2345). Since the regulation came into force, several fires have broken out in dry-cleaning shops that did only by chance not result in harm to shop workers and people living in the neighborhood.
