2 Health & Safety
When working on Kelvin Hughes Ltd equipment, operators, engineers and agents must work within the health and safety
guidelines noted in this handbook and 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.
HAZARDS
The equipment is constructed so that access to high voltages may only be gained after having used a tool, such as a spanner
or screwdriver. Warning labels are prominently displayed both within the equipment and on protective covers.
WARNING: ELECTRICAL HAZARDS
Some equipment does not have safety interlocks fitted.
Lethal single 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 any UPS supported supplies to the system.
WARNING: HIGH VOLTAGES
This product contains high voltages.
Do NOT remove any covers or otherwise attempt to access internal components, unless specifically instructed in this
document.
WARNING: SWITCH OFF POWER SUPPLY
Ensure all power supplies are switched OFF before starting to install this product.
Do NOT connect or disconnect the equipment with the power switched ON, unless instructed in this document.
ANTENNA ROTATION WARNING
WARNING: RADAR SCANNER SAFETY
Before rotating the radar scanner, ensure all personnel are clear.
EQUIPMENT ACCESS
NOTICE: ACCESS TO EQUIPMENT
To meet with electrical safety recommendations, all equipment should be situated in a restricted area where access is only
available to authorised personnel.
Persons entering the restricted area should be aware of the dangers that are present when the system is operational which
include rotating equipment, radiation hazards and where applicable, working at heights
RADIATION HAZARDS
RADHAZ WARNINGS
Avoid exposure to the main beam of a stationary radar antenna.
Avoid standing closer than 2 metres from the central front face of the antenna.
Users of cardiac pacemakers should be aware of the possibility that radio frequency transmissions can damage some devices
or cause irregularities in their operation. Anyone using such devices should understand the risks present before exposure.
The radar scanner transmits electromagnetic energy at microwave frequencies which can be harmful, particularly to the eyes.
Do NOT look at the scanner from close range. Ensure personnel are clear of the scanner when it is powered on.
