2. Safety
The following safety instructions have to be strictly followed! Otherwise you put yourself
and others in danger.
2.1 General information
Intended use
The SKS 575 searchlight is designed for lighting large and far away objects. The range
of the searchlight is up to 3,460 m.
It is intended in particular for use on ships, especially for transfer through the Suez
Canal and complies with the Arab Republic of Egypt, Suez Canal Authority, Rules of
Navigation, Section II Preparation for Transit, Article 28 Searchlight.
It is suitable for ships over 30,000 SC.G.T.
Because of its intense light power the searchlight may not be used to illuminate persons
in the nearby surroundings.
It is not suitable for illuminating, spaces on the ship or in buildings.
Danger! Unauthorised conversions and changes to the searchlight are not
allowed, since this can endanger persons and may damage the unit. If this is not
followed then the unit’s approval becomes null and void.
Only original spare parts may be used. If this is not followed then the guarantee
rights become null and void.
Risk of getting burned! Never touch the searchlight during operation without
protection. The casing can reach 120 °C. Always allow the searchlight to cool
down before maintenance and repair work. In case of burns cool the injured area
immediately and seek medical help.
Risk of glare! Never look into the light source during operation. This is
dangerous for the eyes. Never point the searchlight directly at anyone.
Risk of crushing! Risk of shearing! Before turning or tilting the searchlight:
Make sure that there is nobody right beside it. A persons limbs can get trapped
between the searchlight and the moving mechanism and sustain serious injured.
2.2 How to handle metal halide lamps
Strictly follow the safety instructions below when handling metal halide lamps:
Transport
Always store and transport metal halide lamps in such a way that the glass
bulb cannot break.
Following the removal of metal halide lamps store them immediately in a safe
place where they cannot be broken. If a lamp breaks proceed as described in
chapter 2.3 Protective measures in case of a broken lamp.

Operation
Never touch the naked lamp bulb with your bare hands. Remove fingerprints
on the lamp before installation with an alcohol solution and a soft lint-free
cloth. When handling it is recommended to use disposable gloves to avoid
fingerprints.
Check the lamp for scratches, cracks or other damage before installation.
Don’t continue using damaged lamps.
Lifetime
Metal halide lamps have an average lifetime of approx. 750 operating hours.
The actual lifetime can deviate in practice and depends on the ratio of switching
on frequency to switching on duration.
Disposal
Metal halide lamps contain environmentally hazardous substances (incl.
mercury), and hence in Europe have to be disposed of as special waste as per
the directive EWC-Code 2001 21* for “Fluorescent tubes and other mercury-
containing waste”. Hence metal halide lamps have to be brought to suitable
disposal sites. In other countries the relevant legislation has to be followed.
Metal halide lamps may not be destroyed under any circumstances during
disposal.
Health risks
Breathing in of mercury or mercury compounds in the form of vapour or dust can
damage your health. Apart from inhaling, mercury can also be absorbed by
penetrating the skin.
2.3 Protective measures in case of a broken lamp
We recommend proceeding as follows, in case of a lamp break or explosion, in
order to eliminate any health risks:
All persons in the close surroundings should evacuate the area immediately,
to avoid inhaling mercury vapour.
Ventilate the area adequately for 20 to 30 minutes.
After the lamp has cooled down and in any case before restarting any
residual mercury is to be thoroughly removed from inside the light using
mechanical means.
Disposable gloves are recommended to avoid skin contact. Liquid mercury can
also be absorbed using a standard absorption agent (based on active carbon).

2.4 Safety devices
Radiation/escape of dangerous particles
Metal halide lamps radiate UV light which is harmful to the eyes. The
special searchlight casing prevents you from looking directly into the arc.
If the metal halide lamp explodes during operation, the casing remains
intact and contains any heated glass splinters, see chapter 2.3 Protective
measures in case of a broken lamp.
2.5 Operating conditions
Installation location of the searchlight
Under normal use conditions the casing surface temperatures can go up to 120 °C. Only
install the searchlight close to heat resistant material. To eliminate any dangers: Never
store any explosive or highly flammable materials right beside the searchlight. These
include petrol, paper and paint for example.
2.6 Maintenance / Cleaning
Before carrying out maintenance or cleaning work:
Set the main switch on the PSUH power supply unit to OFF.
Make sure that the complete electrical system is de-energised.
Wait until the searchlight has cooled down.
