§ 6.30 MSHA listing of equivalent non-MSHA product safety standards.
MSHA evaluated the following non-MSHA product safety standards and
determined that they provide at least the same degree of protection as
current MSHA requirements with or without modifications as indicated:
(a) The International Electrotechnical Commission's (IEC) standards
for Electrical Apparatus for Explosive Gas Atmospheres, Part 0, General
Requirements (IEC 60079-0, Fourth Edition, 2004-01) and Part 1,
Electrical Apparatus for Explosive Gas Atmospheres, Flameproof
Enclosures ``d'' (IEC 60079-1, Fifth Edition, 2003-11) must be modified
in order to provide at least the same degree of protection as MSHA
explosion-proof enclosure requirements included in parts 7 and 18 of
