Safety precautions and warnings
To ensure compliance with the IMO standards, installation of the VDR must be performed by
a NetWave Systems approved installation technician. Only a NetWave Systems Certified
Technician should access the interior components of the VDR.
The following precautions and warnings are general safety measures that personnel should
understand and apply during installation, operation and maintenance of all VDR system
equipment.
PERSONAL PROTECTION
Personal protection must be used whenever the possibility of an uncontrolled hazard exists. For
example, a suitable face visor, gloves and a body apron should be worn when handling cathode
ray tubes, as a precaution against injury in the event of breakage.
Some VDR components are heavy; ensure you carry out proper lifting procedures while
changing or transporting components.
LETHAL HIGH VOLTAGES ARE PRESENT IN THE VDR
High voltages are present in the Voyage Data Recorder. Do not open any of the units when
the Voyage Data Recorder is operational unless fully qualified to do so.
Only NetWave Systems Certified Technicians should undertake work on the system.
A current of 100 mA passing through the human body for one second can kill. This can occur at
voltages as low as 35V AC or 50V DC. Some equipment in the system uses electrical power that
can be lethal. Whenever practical, before carrying out installation, maintenance or repair,
personnel involved must:
(1) Isolate the equipment from the electrical supply.
(2) Make tests to verify that the isolation is complete.
(3) Ensure that power cannot be accidentally reconnected.
If it is essential to work on the equipment with power connected, work must only be undertaken
by qualified personnel who are fully aware of the danger involved and who have taken adequate
safety precautions to avoid contact with dangerous voltages.
Wear proper safety attire and use the proper equipment while handling the VDR during transport
and installation.
POWER SUPPLY
Prior to connecting the power supply of the VDR to the ship power, ensure the (emergency) ship
power breaker is switched off. Always shut down the system and turn off the power before
removing or installing any equipment.
