Means of safeguarding personnel while operating or maintaining equipment located in electrolytic cell line working zones are provided. Included are related requirements for equipment and electrical conductor installations. The general types of electrolytic cells covered include, but are not limited to, the dc cells used in the production of aluminum, cadmium, chlorate, chlorine, copper, fluorine, hydrogen peroxide, magnesium, sodium, and zinc.

This standard covers means of safeguarding personnel while operating or maintaining equipment located in electrolytic cell line working zones. Included are related requirements for equipment and electrical conductor installations. The general types of electrolytic cells covered include, but are not limited to, the dc cells used in the production of aluminum, cadmium, chlorate, chlorine, copper, ßuorine, hydrogen peroxide, magnesium, sodium, and zinc. This standard does not cover the following: a) Electroplating and anodizing facilities b) AC cells or furnaces c) Electrothermal process furnaces d) Arc furnaces e) Melting or heat treating facilities f) Any electrical equipment that is neither part of the electrolytic process equipment nor installed or used in the cell line working zone

The purpose of this standard is to provide for the practical safeguarding of personnel while operating or maintaining equipment in electrolytic cell line working zones. The cell line working zone is defined in clause 5. The application of this standard permits alternative methods where it is assured that equivalent objectives can be achieved by establishing and maintaining effective safety and maintenance procedures.
