(8) “high efficiency particulate air (hepa) filter” means a disposable dry filter that has a minimum particle collection efficiency of 99.97 percent when tested with a mono-disperse 0.3 um test aerosol. (9) “hexavalent chromium” means the form of chromium with a valence state of +6.
it is important to realize hexavalent chromium has its own threshold limit value (tlv) that may be lower than other components present as airborne contaminants. remember that hexavalent chromium is usually only a percentage of the dust fume and mist generated and other processes will produce fume containing small amounts of hexavalent chromium.
