And hooray for our side. The EPA's existing chemical exposure limits (ECEL) for DCM promise to be the first of many. And unlike the TLVs and PELs, they are not outdated or constrained by the need or desire to put the health of the industry over the health of the exposed workers. I think I hear the cavalry coming, and about damn time.

Technically, the EPA is not banning laboratory use of DCM. They were
clear on this when we met with them during the comment period.
However, users must develop work plans that meet the EPA use
guidelines for monitoring and exposure limits.

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?”
