VSP 2018 Operations Manual

The UV DISINFECTION system must be maintained and operated in
accordance with the manufacturer’s recommendation. At least one spare
UV lamp must be available.

13.8.3.7 System Shutdown
An automatic shutdown must be maintained whereby any failure in
maintaining the required free residual HALOGEN level, pH level, or UV
lamp intensity must cause the water to completely divert from the BABY-
ONLY WATER FACILITY and instead loop back to the compensation
tank. Additionally, this system must be equipped with an audible alarm
that sounds in a continuously manned space, such as the bridge or engine
control room.

13.8.3.8 Shutdown and Alarm Testing
The emergency shutdown and alarms systems must be tested monthly.
Testing procedures and results must be recorded.

13.8.4 System Cleaning and Disinfection

13.8.4.1 Daily Cleaning of Spray Pad Surface
Every 24 hours, the SPRAY PAD surface and any associated features
must be cleaned with an appropriate cleaner. The surface must be rinsed
and disinfected at 50-ppm free residual HALOGEN for 1 minute, or the
equivalent CT VALUE. Ensure that the liquid waste from this process is
not directed to the compensation tank.

At least every 72 hours, the facility must be shut down and these
procedures must be followed:
1. The entire volume of water within the system must be discharged.
This includes the BABY-ONLY WATER FACILITY,
compensation tank, filter housing, and all associated piping.

2. The BABY-ONLY WATER FACILITY, compensation tank, and
filter housing (cartridge filter) must be cleaned with an appropriate
cleanser, rinsed, and disinfected (chlorine or bromine).
DISINFECTION must be accomplished with a solution of at least
50 MG/L (ppm) free residual HALOGEN for 1 minute, or the
equivalent CT VALUE.

13.8.5 Monitoring and Record Keeping
An automated analyzer-chart recorder capable of recording free residual
HALOGEN levels in MG/L (ppm) and pH levels must be installed.

The system must be checked for calibration before opening the facility for use,
and then every 3 hours thereafter with a test kit accurate to within 0.2 MG/L
