Posted By Mark Preston Try a Google search using Synthetic Graphite MSDS as your search term Or stick this address in your browser... http://www.google.com/se...n&safe=off&start=10&sa=N Google will return mostly US and Canadian sites - with OSHA PELs and ACGIH TLVs which are the same as their PEL/TLVs for nuisance or irritant dust. These suggest that it is less hazardous than natural graphite - because the latter may contain silica and the former does not. This checks out with the much briefer stuff on graphite at Oxford University's useful MSDS site http://joule.pcl.ox.ac.uk/MSDS/

Posted By Jay Joshi There are both total and respirable dust exposure limits for carbon (dust)in EH 40. These limits do not differentiate between natural and synthetic graphite, although the latter may contain impurities of free silica and its implications. Please refer to "Carbon dust : health and safety precautions" HSE Guidance note EH21 for details.It includes graphite/synthetic graphite.
