What is Hexavalent Chromium?

Welders need to be protected from Hexavalent Chromium, also called Hex Chrome or Chrome 6.  Hexavalent Chromium is the most toxic form of chromium. The potential to be overexposed during welding especially if its production welding, or full shift welding on stainless steel should be a concern.

Hexavalent Chromium compounds are breathable carcinogen compounds that contain the element Chromium. Industrial workers are exposed to this dangerous chemical often from industrial processes like welding and thermal spray.   

Without the proper protection and equipment, employees can be seriously harmed by prolonged exposure to hexavalent chromium. Exposure may cause health problems for the welders working directly with the processes and those in areas near by the process. Contaminated air should be filtered through a cartridge collector.

A.C.T. Dust Collectors can help address your company’s process and determine if you need specific dust collection and air filtration to combat Hexavalent Chromium.

Some of the industrial processes that can produce hexavalent chromium and that lead to the inhalation of airborne hex chrome include:

  • Coatings (spray primers/paints)
    • Coatings containing chromates such as dyes, paints, inks & plastics
    • Chrome plating
    • Blending/sanding coatings containing chromium  
  • Welding of alloys containing chromium
    • Stainless steel
    • Nickel Alloy
  • Thermal Spraying, including plasma, electric arc and combustion
  • Smelting of Ferro-Chromium Ore
  • Portland cement impurities
  • Dip-tanks
  • Leather tanning - Ammonium Dichromate
