MIL-HDBK-1130
Fire Protection and Alarm Systems Inactivation
2.2.13
Fire Extinguishers. At least two ordinary pump tank fire
2.2.13.1
extinguishers should be winterized and placed at the exterior of main
entrances to the building or in groups within reasonable distances of smaller
buildings. These extinguishers require periodic inspection at the same
frequencies required for active buildings.
Automatic Sprinklers. Dry-pipe sprinkler systems should be kept in
2.2.13.2
service at all times, and deluge valves and other motivating elements should
be kept well above freezing temperatures, in heated locations, or in dry-pipe
valve cabinets. Wet-pipe systems should also be kept in service at all times,
if economic studies determine that during periods of potential freezing
temperatures, the structures should be kept heated to at least 40 degrees F to
aid in preserving the building and equipment. In all cases, wet systems
should remain active during warm and temperate seasons. This requires proper
drainage and protection against freezing during cold seasons or periods.
Electric strip heaters may be provided for valve enclosures, pits, pumprooms,
etc. where electric service is available. Exceptional conditions may require
conversion of wet-pipe to dry-pipe operation. If water tanks are used as the
primary or reserve supply for fire protection or hydrant systems, suitable
heating facilities for maintaining the water above 40 degrees F should be
provided.
2.2.13.3
Alarm Systems. Automatic fire alarm systems should be kept in
service; in some instances, minor changes may be necessary in the provisions
for receiving alarms from such systems. Manual alarm systems of both the
combination watch-and-fire alarm and the single fire alarm type should also be
kept in service. No changes should be made in the fire alarm box circuits or
box locations when reasonable security and supervision are provided.
Fire Reporting Telephones. Keep systems in service to meet fire
2.2.13.4
alarm transmission requirements. When the administrative switchboard of a
station is disconnected and when the fire-reporting telephone lines terminate
in this switchboard, these lines should be re-terminated in the firehouse
designated for that purpose. Consider providing an extension for
communication to the administrative building. Also, consider combining fire-
and guard-reporting telephones into one system, provided that both systems
have compatible circuit features and are supervised electronically.
2.2.14
Fire Protection and Alarm Systems Reactivation
2.2.14.1
Fire Extinguishers. All fire extinguishers in use should be
inspected, tested, recharged/refilled, or replaced if necessary. Additional
extinguishers of the appropriate type for the location prescribed should be
provided when necessary. See MIL-HDBK-1008A, Fire Protection for Facilities
Engineering, Design, and Construction, for further details.
