Hexavalent chromium standards [Georgia]
July 21, 2010
Need a little help in regards to hexavalent chromium standards. Based on the OSHA regulation I was able to find exposure limits for inhalation, which were helpful; what I really need though is limits for hexavalent chromium in a electrolyte bath. Thus far, I was not able to find such limits. Any help and links would be appreciated.

Hi, Phill. The term chromium "bath" doesn't mean people actually take a bath in it like they would an Epsom salt bath. Consequently there are no OSHA regulations for what the concentration is. Regulations on chromium in the air, yes; regulations on controlling it via mist supressants, yes; regulations on chromium in the wastewater, yes; regulations on chromium in the solids to be landfilled, yes; regulations on hexavalent chromium on the parts that people touch, yes. Regulations on what stays in a drum or a bath, no.
