13.7.5 Cross-Connections on Vessels

13.7.5.1 List of Connections Requiring Backflow Prevention on Vessels
A log listing of all CROSS-CONNECTIONS on the vessel must be
developed. At a minimum the log should contain the data elements in
numbers 2, 3, 6, 7, and 8. Inclusion of the additional data in numbers 1, 4,
and 5 is recommended.
1. Deck (A, B, C, 1, 2, 3…).
2. Location (of connection and of device, if different).
3. Connection description (e.g., hose, chemical tank, coffee machine,
detergent dispenser).
4. Connection subjected to CONTINUOUS PRESSURE (CP) or
noncontinuous pressure (NCP).
5. Connection subjected to [BACKSIPHONAGE only or
BACKSIPHONAGE and BACKPRESSURE].
6. Protection used (AIR GAP or manufacturer name and designation for
device).
7. Inspection date.
8. Inspection results (passed, replaced, psi results).

13.7.5.2 Specific Backflow Protection Choices on Vessels: Air Gaps
and Backflow Prevention Devices

BACKFLOW PREVENTION DEVICES used on the vessel. For each
device, a copy of the specification sheets or technical sheets as well as the
manufacturer’s installation recommendations should be included in the
program documentation file. Generally these documents are available
online from the websites of each device manufacturer.
