(3) No cargo but an alkylene oxide is loaded into a containment system which last carried an alkylene oxide unless the containment system has been cleaned of alkylene oxide to the satisfaction of a Coast Guard Marine Inspector or person specifically authorized by the Commandant (CG-ENG) to approve alkylene oxide tank cleaning; and
(4) No hose marked “For Alkylene Oxide Transfer Only” is used for the transfer of a cargo other than an alkylene oxide.
