The Labor Department's Mine Safety and Health Administration (MSHA) has called for comment from the public on a proposal to revise safety regulations on the use of electricity in underground coal mines and all metal and non-metal (non-coal) mines.
Separate notices of the proposed rule changes for underground coal mining and for metal and non-metal mining appeared in the Federal Register on Dec.
The proposed revision of the existing electrical safety standards apply to Part 75, Title 30, Code of Federal Regulations (underground coal mining), and Parts 56 and 57 of Title 30 (metal and non-metal surface and underground mining, respectively).
based on differing mining environments in the coal and the metal and non-metal industries, differences between surface and underground mining characteristics, and varying risk factors such as the added risk of gas explosions occurring in certain types of mines, but not others.
Proposed electrical safety standards for metal and non-metal mines include a new requirement that certain electrical work be done only by electricians found to be qualified under an operator's training program.
