The person in charge of cargo transfer may not approve or continue cargo transfer unless the following conditions are met:
- (a) No fires or open flames are on deck or in compartments near the hose connections when Table 1 requires the cargo's containment system to have a fire protection system.
- (b) Any electrical bonding of the tankship to the transfer facility is made before the cargo transfer piping is joined.
- (c) Any supplemental inert gas supply necessary to maintain the 3.5 kPa gauge (approx. 0.5 psig) pressure in the tank during offloading (see § 153.500) is connected to the inert gas pressure control system.
- (d) The transfer connections have enough slack to allow for vessel movement.
- (e) The transfer connections are supported by tackles.
- (f) The cargo high level alarms, tank overflow alarms and overflow control systems are functioning correctly when the cargo is loaded.
- (g) Joints and couplings are gasketed and mated tightly.
- (h) Flanges are bolted tightly.
- (i) No repair work is underway in areas where cargo or cargo vapors may collect.
- (j) Cargo and sea valves are properly set, with those sea valves connected to cargo piping lashed or sealed shut.
- (k) Venting system bypass valves are set for cargo transfer and are operating properly.
- (l) All scuppers are plugged.
- (m) Smoking is limited to safe places.
- (n) Fire fighting and safety equipment is ready.
- (o) He is in effective communication with the transfer terminal.
- (p) The person in charge of the transfer terminal has acknowledged that he is ready to transfer.
- (q) Pressures within the cargo transfer and containment systems do not exceed the pressure ranges for which the transfer hose and containment systems are designed.
- (r) No vessels that would hazard cargo transfer are alongside the tankship.
