75.1107-12 Inerting of Mine Atmosphere Prohibited
The term "total flooding" does not mean total flooding with
water, but control of the potentially hazardous area by inerting
the whole atmosphere, i.e., carbon dioxide. This method of fire
control is not recommended in mines because of the limited means
of escape for miners who might be trapped in the enclosed space.
75.1107-13 Approval of Other Fire-Suppression Devices
Where installation of fire-suppression devices on permissible
mine machinery requires alteration of components, a field change
approval will be required.
75.1107-15 Fire-Suppression Devices; Hazards; Training of
Miners
This Section requires the operator to instruct the miners in safe
operating procedures of fire-suppression devices on the equipment
that the miners have been assigned to operate.
The inspector shall take appropriate action in each instance
where the operator fails to instruct the equipment operator.
75.1107-16 Inspection of Fire-Suppression Devices
"Qualified," as used in paragraph (a) of this Section, does not
mean formal training. A person qualified by reason of on-the-job
experience and instruction may be designated by the mine operator
to inspect the fire-suppression devices.
75.1108 Flame-Resistant Conveyor Belts
Conveyor belts which have been approved as flame-resistant by the
Bureau of Mines, MESA, or MSHA are marked every 30 feet on
alternate edges of the coal carrying side of the belt, with the
following: Flame Resistant MESA, U.S.B.M., or MSHA No.
