I have not heard anything specific from our EH&S office, but I just sent them an email after receiving this email. I do not teach an organic lab but we use dichloromethane in our research lab, so I am interested in learning about new regulations.

Subject: [DCHAS-L] Methylene chloride in teaching labs
| This email originated from outside ECU. |
Good afternoon,
Like many others, our institution is currently trying to assess the impacts of the new methylene chloride regulation from EPA, and a question has come up around use of this chemical in teaching labs. Our chemistry department currently
uses methylene chloride for some of their higher level courses. Do activities with methylene chloride conducted in teaching labs qualify as “commercial use as a laboratory chemical”?
How is your institution addressing this issue (if it is relevant for you)?
Any input is appreciated!
Regards,
~Alex
