MSHA PROGRAM POLICY MANUAL <strong>VOLUME</strong> V<br />
When emergency material is stored at a central warehouse or<br />
building supply company, the inspector should determine whether<br />
the material will be available for shipment to the mine at all<br />
times.<br />
75.1100-3 Condition <strong>and</strong> Examination of Firefighting Equipment<br />
All firefighting equipment shall be maintained in a usable <strong>and</strong><br />
operative condition. Rock dust shall be dry, water cars shall be<br />
kept filled <strong>and</strong> operative, water containers <strong>and</strong> pails shall be in<br />
usable condition, <strong>and</strong> chemical extinguishers shall be examined<br />
every 6 months. The inspection of chemical extinguishers should<br />
determine that:<br />
1. The extinguisher is in its designated place.<br />
2. Access <strong>and</strong> visibility to the extinguisher are not<br />
obstructed.<br />
3. Seals should not be broken. This is an indication that<br />
the extinguisher may not be full. Some extinguishers have<br />
to be lifted slightly to determine if they are full.<br />
4. The extinguisher has not been physically damaged or have<br />
any obvious defects (clogged nozzle, corrosion, leakage,<br />
damaged hose, etc.).<br />
5. The examination record on the tag is up-to-date. This<br />
section is interpreted to mean that water shall be kept<br />
constantly in the waterlines in sufficient amounts to meet<br />
the requirements of Section 75.1100-1(a). The phrase "50<br />
gallons of water per minute," as used in Section 75.1100-<br />
1(a), does not mean for only 1 minute.<br />
In those instances where there is danger of freezing <strong>and</strong> bursting<br />
the waterlines if water is kept in the lines, the mine operator<br />
should consider a pressurized system, or should file a petition<br />
for modification under the provisions of Section 101(c) of the<br />
Act.<br />
75.1101 Deluge-Type Water Sprays, Foam Generators; Main <strong>and</strong><br />
Secondary Belt-Conveyor Drives<br />
In requiring fire suppression systems for belt conveyor drives,<br />
apply the same rule used in Section 75.603 <strong>and</strong> in Section 75.1103,<br />
which permit the use of belt conveyor drives without a fire<br />
suppression system for 24 production shift hours after they have<br />
been installed before a citation is issued.<br />
