Hi Jonathan ,
Is your institution a member of CSHEMA? If so, you can access a variety of resources developed for communication about DCM:

Subject: [DCHAS-L] How should DCM be handled in a chemical hygiene plan?
Hey all,
We are updating our chemical hygiene plan and were wondering if you all could provide some guidance on how DCM should be written in the plan. We have a category for halogenated wastes, but with the new rules do we need to separate halogenated
waste from DCM? Do we need to include more language about measuring exposure, etc?
Thank you for any help you can provide.
