Hi, this is a very good topic to discuss. Methylene Chloride (dichloromethane) about this substance we have these news and information that are not so good. Here we can make a parenthesis and start with an investigation. Where do we find this substance, in which manufactured products is it found, who produces it... how can we find a correct alternative and if the EPA will ban this substance. The effects in the international correction of the prohibition of this substance.
And many other interesting things that I think will be discussed at webinar on the subject:

Good Afternoon All-
Hope all is well. So, our Procurement director (Now an expert in chemistry) is concerned on the use of DCM because a panel discussion came across an Insurance discussion email. Please see below. I would appreciate any information and
what other Institutions are doing. We are following the SDS and other proper protocols (NIOSH exposure limits and skin protection). Also, it is mainly used in our Organic chemistry labs.
Kind Regards,

Hello Everyone,
I have a member input request for the group on
Methylene Chloride (dichloromethane)-
“The EPA will be banning
methylene
chloride (dichloromethane) and I was wondering if any of the labs currently using it will plan on either requesting use of alternatives (ethyl acetate, MTBE, toluene, 2-MeTHF) or will start to perform
testing to ensure there is no over exposures?”

Management for Methylene Chloride | US EPA
Thank you,
