B.16 An air operated hose-banding machine bands hoses to fittings more
securely than a hand operated machine.
B.17 Two bands rather than three can band hoses and fittings securely.
B.18 For storage of coiled sewage hoses on shelves, the shelves should have
a minimum 12-inch clearance for their entire depth.
B.19 Locating a hose washing trough immediately in front of a hose storage
rack should be avoided, as it can lead to accidents and injury.  Where this
has already been done at San Diego, no more than two hose lengths should be
washed in the trough at a time, to minimize the risk of accident.
B.20 It was observed in some ship-to-shore sewage connections that large
accumulations of residual water were present in the hoses, such as in a
catenary between a ship and the pier, or when a ship's deck riser was lower
than the pier riser to which the ship was connected.  Purging of the water
by compressed air was accomplished by installing a half-inch, valved nipple
in the female hose coupling that connects to the ship sewage deck riser.
The ship riser valve was closed and the air pressure applied to hoses for 30
seconds. The compressed air purged the hose almost totally. This technique
is used regularly where a ship-to-shore connection could result in a drain
back spill on a ship's deck during a disconnection operation.
B.21 In passing sewage hoses to submarines that are outboard in nested
berths, be sure that a metal cap is in place in the hose being passed. This
permits flotation of the total hose and makes for an easier hose transfer
operation.
