(a) Each hose within the marine transfer area for LHG used for the transfer of LHG or its vapors to or from a vessel must--
(1) Be made of materials resistant to each LHG transferred, in both the liquid and vapor state (if wire braid is used for reinforcement, the wire must be of corrosion-resistant material, such as stainless steel);
(2) Be constructed to withstand the temperature and pressure foreseeable during transfer, with a MAWP not less than the maximum pressure to which it may be subjected and at least 1030 kPa gauge (149.4 psig);
(3) Be designed for a minimum bursting pressure of a least five times the MAWP;
(4) Have--
(i) Full-threaded connections;
(ii) Flanges that meet ANSI B16.5; or
(iii) Quick connect couplings that are acceptable to the Commandant;
(5) Be adequately supported against the weight of its constituent parts, the LHG, and any ice formed on it;
(6) Have no kinks, bulges, soft spots, or other defects that will let it leak or burst under normal working pressure; and
(7) Have a permanently attached nameplate that indicates, or otherwise be permanently marked to indicate--
(i) Each LHG for which it is suitable;
(ii) Its MAWP at the corresponding service temperature; and
(iii) If used for service at other than ambient temperature, its minimum service temperature.
(b) Each loading arm used for the transfer of LHG or its vapor must--
(1) Be made of materials resistant to each LHG transferred, in both the liquid and vapor state;
(2) Be constructed to withstand the temperature and pressure foreseeable during transfer;
(3) Be adequately supported against the weight of its constituent parts, the LHG, and any ice formed on it;
(4) Be provided with an alarm to indicate when it is approaching the limits of its extension, unless the examined Operations Manual requires a person to perform the same function; and
(5) Have a permanently attached nameplate that indicates, or otherwise be permanently marked to indicate--
(i) Each LHG it may handle;
(ii) Its MAWP at the corresponding service temperature; and,
(iii) If it is used for service at other than ambient temperature, its minimum service temperature.
