    1.°.) POTABLE WATER SYSTEM 1.11) GENERAL The term potable water. as used herein means water meeting the require- ments of the United States Public Health Service Drinking Water Stand- ards. One water system supplying potable water for drinking, cooking, dish- washing, ablutionary, hospital and laundering purposes should be in- stalled when practicable. If dual Systems are installed, potable water should be piped to outlets which may be used for drinking, cooking, dish- washing and medical care purposes (exclusive of hydrotherapy in those spaces), but it need not be piped to slop sinks, lavatories, laundry facilities, bath tubs, showers, water closets, and bibb connections used for deck flushing purposes. It is preferable from a public health standpoint that water for potable water purposes be secured from approved shore supplies. When that is done, the responsibility for water purification rests upon a trained, professional waterworks operator who has laboratory facilities, equipment, supplies, and expert advisory service available when needed. When purification on board becomes necessary, the method selected for use should bethat best suited to the water to be treated and most easily understood by the operating officers and seamen. 1.2 LOADING FACILITIES 1,219!) Hose. A Separate hose should be provided for loading potable water from shore sources. The hose should be durable, have a smooth im- pervious lining, and be equipped with the necessary fittings for fasten- ing it to the filling line and the hydrant. It is preferable that the fittings be different from those on other hoses on the vessel and that Suitable adapters be stowed for connecting them to hydrants. Potable water loading hose should be provided on the vessel unless hoses are maintained by the vessel operating company at all piers of ports of call Where potable water is loaded. If the specific needs of the vessel are not known, at least two 50-foot sections should be provided. 1,22 Hose Stowage. The potable water loading hose and such hydrant. adapters as are required should be stowed near the vessel’s filling line connection unless the operator elects to provide stowage facilities at all piers where potable water is to be loaded. They should be stowed in a closed cabinet, on a rack or reel, or they should be placed under a deckhead or on the upper part of a bulkhead of an interior passageway. The cabinet, rack, or reel should be at least 18. above the déck and a (1) A whole figure designates a Part; a figure with one decimal, a Subpart; one with two decimals, a Section.
