(c) Cargo connections have been made as described in § 35.35-15 and cargo valves are set.
(d) All cargo connections have been made to the vessel's pipeline, and not through an open end hose led through a hatch.
(e) In loading Grades A, B, and C cargoes, there are no fires or open flames present on the deck, or in any compartment which is located on, facing, open, and adjacent to that part of the deck on which cargo connections have been made.
(f) The shore terminal or the other tank vessel concerned has reported itself in readiness for transfer of cargo.
(g) All sea valves connected to the cargo piping system are closed.
(h) In loading Grades A, B, and C cargoes, that an inspection has been made to determine whether boiler fires can be maintained with reasonable safety.
(i) In loading Grades A, B, and C cargoes, that an inspection has been made to determine whether galley fires can be maintained with reasonable safety.
(j) In loading Grades A, B, or C cargoes, that an inspection has been made to determine whether smoking may be permitted with reasonable safety in areas other than the weather deck.

(See § 32.20-20 of this subchapter.)
(m) When a transfer operation includes collection of cargo vapor from a vessel's cargo tanks through a vapor control system not located on the vessel:

(9) The oxygen content of the vessel's cargo tanks, if inerted, is at or below 8 percent by volume.
