>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?"

Potentially, if it is able to keep the worker exposure levels below PEL of 25 ppm. The good news is that you can document the containment or lack thereof pretty straightforwardly by sampling the workplace during use of the methylene chloride.

Let me know if you have any questions about this.
