MIL-HDBK-1032/2
6.2.10
Sealants, Fasteners, and Adhesives. Sealants, fasteners, and
adhesives used for installing insulation shall not impair the integrity of the
vapor barrier system. Metal skewers shall not be used as fasteners. Adhesive
and sealants shall not be used in multilayer construction in a manner that
will create restrictive vapor dams which may cause internal condensation and
possible frost formation. Fasteners and adhesives shall be applied only to
reasonably smooth surfaces.
6.2.11
Built-up Roofing Over Deck Insulation. The extreme conditions under
which a built-up roofing system must operate when over a cold storage facility
increases the possibility of failure. -Installation of built-up roofing over
cold storage areas shall be incorporated as part of the cold room insulation
work to permit a more forceful coordination and inspection of the roofing that
is applied over the insulation.
6.2.12
Doors. Door heaters shall be included when needed to prevent frost
and moisture accumulation on door gaskets. Also reconsider recirculating air
curtains on both sides of all doors between areas of differing temperature.
6.2.13
Refrigeration Systems. Refer to NAVFAC DM-3.04 for guidance on the
selection of refrigeration systems for cold storage warehouses.
Special Equipment Ratings. Cold storage equipment conditioning
6.2.14
includes hydraulic, mechanical, and electrical modifications for trucks which
will be used in cold storage applications. Class I conditioning, consisting
of special condensation protection, shall be applied to trucks operating in an
environment where temperatures fluctuate from normal warehouse ambient
temperature to 32F (0C). Class II conditioning, consisting of battery
heaters, hydraulic system modifications, and condensation protection, shall be
applied to trucks operating in an environment where temperatures fluctuate
from normal warehouse ambient temperature to -40F (-40C) or where
continuous operation at temperatures of 32F to -20F (0C to -29C)
is expected.
6.2.15
Alarms. Cold storage facilities shall be equipped with safety,
security, and high temperature alarms.
6.2.15.1 Safety Alarm. Each room shall have a pushbutton wired to an alarm
bell outside the room and to a location manned or monitored on a 24-hour basis
so that any person locked inside the room can call for help.
6.2.15.2 Security Alarm. When a security system is present, alarms shall be
installed to indicate unauthorized entry to the building or individual storage
rooms.
6.2.15.3 High Temperature Alarm. Alarms to indicate compressor faults or
excessive temperature in cold storage spaces shall be located both locally and
in the office or other supervisory area. Panel-mounted alarm lights with
audible alarms and manual silencing switches shall be provided for each room
and for each compressor.
