[sudo-discuss] Carbon Fiber Dust?

Hi folks, I'm writing on behalf of Common Humanity Collective, a local mutual aid collective that distributes free masks and DIY air purifiers to the community. We've been looking for access to a laser cutter that has NOT come into contact with or been in the vicinity of any carbon fiber dust/residue - we don't want anybody breathing that in because we accidentally transferred some to our air purifiers! I realize this might not be possible to answer b/c so many people have worked in the space, but have people worked with carbon fiber at sudoroom before? Are there any rules allowing/forbidding it from use? Any info would be helpful, thank you! -Skylar
