(2) SAFETY ADVICE
S2 Keep out of reach of children.
S8 Keep container dry.
S26 In case of contact with eyes, rinse immediately with plenty of water and seek medical advice.
S43 In case of fire, use D type extinguishers. Never use water.
S45 In case of accident or if you feel unwell, seek medical advice immediately (show the label
where possible).
(3) FIRST AID MEASURES
In case of contact of cell contents with eyes, flush immediately with water for 15 min. With skin, wash
with plenty of water and take off contaminated clothes. If inhaled, remove from exposure, give oxygen,
and seek medical advice.
(4) FIRE-FIGHTING MEASURES
Extinguishing media
Suitable: Type D fire extinguishers
Not to be used: Water - CO2 - Halon, dry chemical or foam extinguishers
Special exposure hazards
Generation of chlorine, sulphur dioxide, disulphur dichloride during
thermal decomposition.
Special protective equipment
Use protective working boots, rubber apron and safety glasses with side shields.

INSTRUCTIONS FOR KEEPING THE RADIO LOG AND THE RADIO OPERATORS
OBLIGATION ACCORDING TO NATIONAL AND INTERNATIONAL REGULATION.
1. The radio log shall be kept in accordance with requirements in the Radio Regulations, SOLAS
Convention, national regulations regarding radio installations and the STCW Convention (STCW 95
including the STCW Code) including the relevant regulation regarding watch keeping on board
passenger and cargo ships.
2. Unauthorized transmissions and incidents of harmful interference should, if possible, be identified,
recorded in the radio log and brought to the attention of the Administration in compliance with the Radio
Regulations, together with an appropriate extract from the radio log. (STCW Code B-VIII/2 No.32)
TEST OF RADIO EQUIPMENT AND RESERVE SOURCE OF ENERGY
Weekly:
GMDSS handheld VHF transceivers to be tested without using the mandatory required emergency
batteries.
Monthly:
Float-free and manual EPIRBs to be checked using the means provided for testing on the equipment.
Check data for periodical maintenance requirement for float-free EPIRB search and rescue radar
transponders (SART) to be checked against 9 GHz radar.
False alerts transmitted by EPIRB
False alerts are a serious problem for the rescue service. Nearly 90% of EPIRB initiated distress alerts
turn out to be false alarms.
If for any reason, your EPIRB should cause a false alarm, it is most important that you contact the nearest search and
rescue authority and tell them it was a false alarm. They can then stand down any rescue service (coast radio station or
appropriate CES or RCC). Use any means at your disposal to make contact. Switch off the distress alarm by de-
activating your EPIRB, as soon as possible.

1GENERAL DESCRIPTION
Tron SART is emergency equipment consisting of:
1.Tron SART radar transponder.
3. Mounting rope for life rafts / life boats.
The 9 GHz radar transponder type Tron SART is developed by Jotron AS to meet the regulations and rules
for use on vessels and life rafts in the maritime service.
Tron SART meets the specifications for 9 GHz radar transponders for use in search and rescue operations
at sea.
The operating range of the Tron SART is up to 30 nautical miles, depending on the height of the electronic
unit and the radar height of the search and rescue unit (sea or airborne).
With a radar height of 20m and the Tron SART placed at 1m above sea level, the range will be up to 10
nautical miles.
Tron SART is buoyant, however to obtain maximum performance the transponder should be placed in a
vertical position and as high up as possible in order to achieve maximum coverage.
Several mounting brackets and mounting aids are developed to ease a correct mounting and use of the
radar transponder.
The purpose of the Tron SART is to perform a secondary alarm when search and rescue units are searching
for a life raft / lifeboat in distress. The Tron SART will help the units to pinpoint exactly where the
distressed boat is located in a larger area. This is done with the help of the radar on the searching ship or
helicopter.
When the Tron SART is interrogated (hit) by a radar signal, it will immediately start to transmit a number
of sweeps covering the complete maritime 3 cm radar band.
These sweeps are detected on the radar screen and are used to navigate directly towards the distressed life
raft, for details on radar display see chapter 5.3.
Maximum distance to a ship will normally be about 10 nm and approximately 30nm to a helicopter,
dependent on the helicopters altitude. The transponder will not give any alarms further away than this.
The primary alarm will usually be an Emergency Position Indicating Radio Beacon (EPIRB) or distress
call on VHF / HF - manual or via digital selcall.
The Tron SART should be activated immediately after the EPIRB has been started or by instructions from
the rescue control centre.
The batteries of the Tron SART will last at least 96 hours in standby after activation and then minimum
8 hours of continuous operation.
