Graphite Dust Collection System | RoboVent

OSHA's most recent standard for synthetic graphite is for total dust and stands at 15 mg/m 3. An exposure limit of 1.5 mg/m 3 is rather rigorous, given it's for a substance that often ends up in a chewed pencil. As a comparison, the PEL for respirable nickel is 1.0 mg/m 3. The key fact is the danger of the respirable substance, and this is ...
