There is an exemption for using methylene chloride in laboratory work. You should replace it if you can, but use good practices to prevent exposure if you can't. Monona

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?”

Thank you,
