 SECTION 3.
HOSE SUPPORT FACILITIES
3.3.1 LOCATION. Sewage hoses should not be stored on piers, even when stored
near the berthing spaces they serve. First, there is usually a shortage of
space on piers, making it impractical to consider storing additional gear under
crowded conditions. Second, the probability of damage to the hoses is in-
creased if they are left unattended on piers, where there is continuous move-
ment of machinery and materials. Finally, adding to pier clutter by leaving
coils or lengths of 4-inch diameter hose laying around increases safety hazards
to personnel.
3.3.2 HOSE STORAGE AND CLEANING. Consolidated hose storage offers an economic
advantage. Central sewage hose storage on large stations reduces the number
of hoses required per station. Deployment of hoses to match the number of
ships needing service at any particular time calls for less hoses than keeping
an adequate number of hoses in storage at each pier riser.
A central hose cleaning/storage yard should be sized for convenient load-
ing and unloading of 50-foot lengths of hose from the transport vehicle. A
minimum installation would cover an area of about 50 feet by 80 feet, and would
accommodate the repair, maintenance, and storage of sewage transfer hoses.
All hose handling and storage facilities are required to incorporate the fol-
lowing design features to preclude the occurrence of conditions which could
promote accidents or communicable diseases:
a. Racks and Tables. Racks and tables used for the handling and storage
of sewage transfer hoses shall be constructed of metal or other impervious
material. Wooden racks and tables are prohibited.
b. Screening. All windows and doors which open to the outside shall be
screened adequately to prevent the entry of flying insects.
c. Back Syphonage Devices. These devices must be installed on all pota-
ble water lines used for flushing and cleaning sewage transfer hoses.
d. Lavatories and Showers. These facilities should be provided and
equipped with hot and cold running water, dispensable soap, and single use
towels shall be provided.
e. Ventilation.
Sufficient ventilation shall be provided in all indoor
work spaces.
f. Safety Precautions. Incandescent and fluorescent lights shall be
protected from breakage. Non-slip surfaces shall be installed on the decks in
the hose washing areas.
g. Hose Cleaning. Sewage transfer hose disinfection normally is not
required; however, the hose handling facility should have the capability to
disinfect them in the event the need arises. One or more small tanks of
chlorine solution should be located near the manifold. An eductor will be
used to draw the detergent solution from the tank(s) while the hoses are being
filled with fresh or salt water.
