Greetings all,

We have a laboratory that wants to use methylene chloride (dichloromethane) to coat materials.

Methylene chloride is an IARC Group 2A potential human carcinogen. As such, it becomes a “particularly hazardous substance” under the OSHA lab standard and according to the standard, must be handled in a “containment.”

Is a spray booth considered a “containment?”

Thanks,

Chris
