A maximum of 72 hours will be allowed for manual tests while repairs are under
way. If more than 72 hours pass, the facilities must be shut down until repairs
are completed.

A log must be kept to detail all maintenance activities, including the following:
• Filter changes including filter housing cleaning and DISINFECTION
(including ppm and contact time).

One test must be conducted at the end of each day for the presence of
Escherichia coli (E. coli) using a test in accordance with the latest edition of

housing, and all associated piping.
• Use an appropriate cleaner on the BABY-ONLY WATER FACILITY,
compensation tank, and filter housing (cartridge filter), then rinse and
disinfect them (chlorine or bromine). DISINFECTION must be
accomplished with a solution of at least 50 MG/L (ppm) for 1 minute, or
the equivalent CT VALUE.
• Conduct follow-up testing. The facility must not be put back in operation
unless follow-up test results are negative for the presence of E. coli.

A record of the test results must be maintained onboard the vessel and must be
available for review during inspections. Retain records for 12 months.

The maintenance logs, records, and charts must be kept for 12 months.
