 h. Health and Safety Requirements. The sewage hose handling and stor-
age facility shall be constructed, equipped, and operated in conformance
with appropriate health and safety requirements promulgated by the Occupa-
tional Safety and Health Administration (OSHA).
3.3.3 HOSE STORAGE METHODS. After they have been cleaned, sewage hoses are
placed in storage. The use of special storage racks is optional. More
storage space is afforded with a rack than with storing hoses on the ground.
a. Ground Storage. The simplest method of hose storage is to place
them on the ground in coils or in straight lines.
(1) Coiled Hose Storage. Coiled 50-foot lengths of hose can be
placed neatly upon a paved surface in the storage yard. Hoses in storage on
the ground are separated by size and type, and may be stacked several coils
high. Protective covers may be required in cold weather climates so that
hoses do not become covered with snow and ice.
(2) Straight Hose Storage. Rubber collapsible and noncollapsible
hoses also may be stored in straight 50-foot lengths on the ground. This
method of storage is particularly convenient when using the powered hose
reel for carrying the hoses to and from the vessels. With this method the
hoses are laid out in straight lines adjacent to one another. As with stor-
ing coiled hoses, the different types of hoses are not mixed, although they
may be placed adjacent to one another. Only a single layer of hoses should
be used when hoses are stored in straight lines. Thus, an area approximately
50 feet long by 25 feet wide can be made to accommodate fifty sewage hoses.
Figure 3-17 shows hose storage on the ground in both coils and straight
lines.
b. Rack Storage. Just as with ground storage, racks allow for storage
of sewage hoses in coils or straight lengths. See Figure 3-18. One type of
storage-rack installed at NAVSTA, San Diego, consists of a series of concrete
shelves, each about 50 feet long and 4 feet deep. The rack is erected at
the edge of a hose washing apron. Spacing between the shelves is about eight
inches, and the top shelf is approximately 6 feet above the ground. Each
shelf can hold four 4-inch wide sewage hoses laid out in straight lines.
The entire rack can accommodate approximately sixteen 50-foot lengths of
sewage hose.
c. Problems Encountered. The concrete hose racks in San Diego were
found to be unsatisfactory for storage of coiled, collapsible rubber sewage
hoses.
(1) Storage Space Problems. The narrow clearance of 8 inches
between the shelves made it difficult to insert and remove the coils of hose.
This problem may be corrected in future designs by spacing shelves farther
apart, with hose coils stored as shown in Figure 3-19.
Trial runs at San Diego also showed that storage shelves much
higher than 5 feet are not likely to be used for hoses in frequent use.
Lifting of hoses above chest level was found to be awkward and tiring, thus
reducing efficiency of operation.
