SECTION VI. PREPARATION FOR STORAGE OR SHIPMENT
4-33. Storage Requirements. Because the MK12 SSDS is a life support system, careful handling and storage is
required. Specific storage requirements for certain components are covered by the storage serviceability standards
supply bulletin SB 7402-97-01 for TROSCOM material diving equipment sets ancillary items, life support equipment
ancillary items.
a.
Short Term Storage. Components for the breathing system are packaged individually inside two heat-sealed
bags. These bags maintain the components in a clean condition; the components should not be removed until
installation on the MK12 SSDS. When stored or shipped, components shall be packaged in the MK12 SSDS storage
container.
b.
Long Term Storage. If components are to be stored for more than three months, prepare for storage as
described in the unit operating procedures. Wrapping and packing are not required unless shipment is anticipated.
c.
Storage Precautions. General storage precautions are listed below:
(1)
Components shall not be stored near fire or at temperatures higher than 120°F (48.9°C) or lower than
0°F (-17.80C). The equipment shall not be exposed to direct sunlight for prolonged periods as sunlight has a
deteriorating effect on rubber components such as hoses and cables.
(2)
Components shall be clean and dry with specific parts lightly lubricated as specified for MK12 SSDS,
this prevents damage and deterioration during storage.
(3)
To protect equipment from dust, dirt, and humidity, components shall be sealed in bags with desiccant
packages.
(4)
To prevent damage from pressure and weight, components shall not be stacked unless wrapped and
packed. Care shall be taken to prevent continuous distortion of flexible parts and pressure from heavy parts on fabric or
rubber components during storage. Rubber items shall be stored without folding or creasing to prevent permanent
distortion of the items.
(5)
To prevent damage and deterioration, do not lay components or sealed plastic bags on bare concrete,
masonry, or earth floors for prolonged periods. Storage racks should be at least six inches from the floor. Ensure that
the storage area is well ventilated, and no corrosive or violative fumes or grease are present.
