k) Consider all potential exposure problems caused by new
construction or additions. Solutions include blocking windows, water curtains,
or separations.
Coal Facilities. The following items shall be considered in coal
10.13.1
facilities. It should be remembered that the probability of a fire in a coal
facility is dependent on the type of coal used, the method of storage and
conveyance, and the degree to which the coal is crushed and conditioned.
10.13.1.1 Fire Hydrants. Adequate fire hydrant protection shall be provided
for all coal piles. Consideration should be given to the long term methods of
coal pile storage to minimize spontaneous combustion. Fires are generally
extinguished by moving coal and compacting, but hosing smoldering heaps may be
required.
10.13.1.2 Coal Bins. Coal bins or bunkers will require temperature and/or CO
monitoring for hot areas which may be conducive to spontaneous combustion.
10.13.1.3 Conveyers. Conveyer systems shall be of noncombustible
construction and noncombustible conveyor belts should be used. These systems
shall be designed to minimize the chances for the accumulation of coal dust.
10.13.1.4 Feed Systems. The feed systems from storage areas shall be
arranged so that the coal can be used or rotated regularly to decrease the
chances for spontaneous combustion.
10.13.1.5 Emptying Capability. All bins and bunkers shall be capable of
being easily emptied to a remote site in the event of a fire.
10.13.1.6 CO2 Protection. Carbon dioxide protection shall be considered for
all bunkers, bins, and silos.
10.13.1.7 Automatic Extinguishing. Areas requiring automatic, semi-automatic
or manual extinguishing systems include emergency generator areas, coal
unloading, crusher housing, plant control centers, flue gas baghouse and front
areas of oil fired boilers.
10.13.1.8 Operation.
Coal handling procedures shall work on First In First
Out principle.
10.13.1.9 Horizontal Surfaces. To the maximum extent possible, the interior
design of the plant shall minimize horizontal surfaces on which coal dust
might collect.
Electrical Criteria. Electrical service shall be in accordance
10.14
with MIL-HDBK-1004/4, Electrical Utilization Systems. Power and lighting
shall be provided to all structures, stairs, platforms, tunnels, conveyers and
areas of access or requiring maintenance. Lighting shall be provided for
night-time coal yard operations, fuel unloading, handling and storage
operations, parking areas and peripheral security around the outside of the
facility.
