2 Health & Safety warnings
When working on Kelvin Hughes equipment, operators, engineers and agents are expected to work
within the health and safety guidelines noted in the handbook, as issued by their respective employer
or as stated by site regulations, shipyard or vessel owner.
Risk assessments of a working area must be undertaken prior to commencement of any work and
must be regularly reviewed.
2.1 Hazards
ELECTRICAL HAZARDS:
Some equipment does not have safety interlocks fitted.
Lethal single and three phase AC and DC voltages may be present when units are open
and exposed.
Before accessing any internal parts, ALL power sources to the equipment must be fully
isolated; this must include the isolation of all UPS supported supplies to the system.
MAINS VOLTAGES:
All Kelvin Hughes equipment is supplied with mains input voltage set for 220v, 50/60 Hz
ac unless otherwise stated on labels attached to the equipment.
WARNING: Some equipment contains materials which may produce toxic fumes if burnt.
Beryllium warning: The SharpEye
TM
X and S band transceivers mounted within
the SBS-800 series are factory sealed units which contain no field serviceable
parts. The SharpEye
TM
transceivers must not be dismantled in the field as some
components within the factory sealed processor contain Beryllium which is
hazardous to health.
Class 1 laser product: There is a class 1 laser within the sealed SharpEye
transceiver processor which can represent a risk if the processor is
dismantled.
When fitted, the LAN fibre optic cable that connects to the SharpEye
TM
transceiver and the to the MISM type 5 modules within the radar distribution
unit is considered as a class 1 laser.
2.2 Antenna rotation warning
ANTENNA ROTATION SAFETY NOTICE:
When single and three-phase power is connected to the system and switched ON, the
antenna will rotate immediately regardless of the RUN command status.
Use the antenna rotation keyswitch or man aloft safety switches to stop antenna rotation
in an emergency.
