Is the ECG process compatible with the recently revised OSHA regulations on airborne hexavalent chrome?
Certain types of electrolytes can produce hexavalent chrome when cutting stainless steels and other metals with chromium as an alloy. The amount of hexavalent chrome in the electrolyte will increase as more metal is cut and the electrolyte becomes more contaminated with metals. As electrolyte is applied to the rotating grinding wheel a mist is created. The mist should be contained within the machine guarding and not allowed to enter the work area. A properly working mist collector is critical to evacuate the machine cabinet and prevent mist from exiting the guard during part loading and unloading. Electrolyte such as Everite Formula GT will not produce hexavalent chrome when cutting stainless steels but a mist collector is still required to protect the operator and surrounding equipment from exposure to the high salt level.
