The Mine Safety and Health
Administration's standards and regulations for diesel-powered
equipment in underground coal mines serve to protect coal miners
who work on and around diesel- powered equipment. The internal
combustion engines that power diesel equipment expose miners to
fire and explosion hazards in the confined environment of an
underground coal mine, which contains combustible coal dust and
highly explosive methane gas.
A reduction of 85 burden hours
(from 708 to 623) reflects a reduction due to a previously reported
training burden that should not have been included, and an increase
in the number of respondents (from 148 to 165). The number of
responses decreased by 591 (1004 to 413) since the first year
included an inventory of all equipment and this submission includes
only changes to equipment. A reduction in the burden cost (from
$8,000 to $6,409) was a direct result of the correction in
previously reported training costs.
