UNLOADING HOSES FOR STORAGE
Section 1. UNLOADING HOSES
10.1.1 REMOVAL FOR THE TRANSPORT VEHICLE. This chapter deals with removing
sewage hoses from the transport vehicle upon return to the storage area.
The hoses should have been cleaned by salt water flushing as part of the
disconnection procedure. BUMED policy states that the salt water flushing
is adequate for cleaning the interior of the hoses. To date this has been
confirmed by the testing done in San Diego. Therefore, hoses normally will
be unloaded from the transport vehicle and placed directly into storage.
Sewage hoses are cleaned and disinfected upon return to the washing/
storage area when it is believed that salt water flushing at the pier may
not have been effective. Hoses that are found to have a strong sewage odor
or those coated with grease on the inside would require additional cleansing
steps. For proper disinfection/decreasing procedures, see Appendix A.
As hoses are returned to the washing/storage facility, they may be
unloaded from the transport vehicle either manually or with the assistance
of powered machinery. Identical procedures are used for unloading both col-
lapsible and noncollapsible rubber hoses.
a. Collapsible and Noncollapsible Rubber Hoses To Be Washed. The steps
given below are followed for manual unloading of sewage hoses brought to the
yard in tight, 50-foot coils on the transport vehicle:
(1) The transport vehicle carrying the coils of rubber hose is
parked as close to the wash rack or apron as possible.
(2) Both members of the two-man shore crew grasp a single 50-foot
coil of rubber hose near the tailgate of the vehicle, lift it together, and
carefully place it on the ground at the end of the wash rack or apron; coils
of hose must not be dropped from the bed of the vehicle to the ground, as
this will damage hose fittings.
(3) One man unrolls the coil of rubber hose into a straight line
adjacent to the wash rack or on the washing apron;
(4) The operation is repeated until all coiled lengths of hose in
the transport vehicle are unrolled in straight lines on the ground adjacent
to the wash rack or on the washing apron;
(5) When the unloading operation is complete, all of the hoses
will be lined up with their female couplings aligned toward the truck.
b. Power-assisted Unloading of Hoses To Be Washed. Unloading of sewage
hoses with assistance from power equipment will occur mainly when the hose
is carried on a trailer-mounted powered hose reel. The steps for unloading
used hose from a powered hose reel are as follows:
(1) The vehicle transporting the trailer-mounted, powered hose
reel is parked as close as possible to one end of the hose washing rack or
