examination for every other dangerous condition and leave
his initials and the date at the places examined. If a

(11) Obedience to Order to Leave Mine;
Examinations and Records by Mine Inspector. No person
ordered by the mine foreman to leave a mine because of
ventilation difficulty may reenter until the mine foreman
gives permission. If it is a gassy mine, the permission may
not be given until the mine foreman or fire boss has
examined it thoroughly and reported it safe. At each visit
to a mine, the district mine inspector shall examine the
records of ventilation and inspect every apparatus and every
procedure for conducting, controlling, or supplying
ventilation. He shall see that each requirement of this
subtitle or rule or regulation relating to it, is enforced.
He shall keep a detailed record of each inspection and every
action taken.]

(a)  An accumulation of gas may not be removed from any
part of a mine by brushing or using water. An operator, mine
foreman, or fire boss knowingly may not permit this to be
done. A worker may not remove the accumulation of gas in the
manner prohibited by this subsection.

(b)  The operator immediately shall notify the district
mine inspector of any large body of explosive gas discovered
in any mine, whether or not any explosion has occurred. He
shall direct and see that immediate steps are taken to
remove the gas, by properly directed air currents carrying
adequate ventilation up to the face from which the gas
exudes, or by other appropriate means. An open flame may not
be permitted in the affected portion of the mine. Every
precaution against an accident shall be taken.

(c)  The mine foreman shall see that every mine
generating explosive gas is kept free of standing gas in
working places or roadways. An accumulation of explosive or
noxious gas shall be removed from a worked out or abandoned
portion of any mine as soon as possible after its discovery
unless the gas is securely and safely sealed in accordance
with the Bureau's rules and regulations. Until the gas has
been removed, no person who may be endangered by its
presence and who is not engaged in removing it may remain in
the affected portion of the mine. The entrance to a worked
out and abandoned part of a mine and every other dangerous
place where gas may accumulate shall be fenced off properly
with a danger signal posted on it.

(d)  Any worker immediately shall notify the mine
foreman if explosive or noxious gas is discovered. The
worker shall see that no gas blower is left burning when he
