Slide 1 · MARITIME KNOWLEDGE

MARITIME KNOWLEDGE FOR A SAFER TOMORROW BE PREPARED. BE SAFER AT SEA. GMDSS & SURVIVAL EQUIPMENT DIFFERENT DEVICES. A SAFER TOMORROW. KNOW THEIR ROLE. BE EXAM READY. Same Goal Safer Lives SART SEARCH AND RESCUE TRANSPONDER EPIRB 406 MHz SailR EEBD EEBD ESCAPE IMMERSION SUIT SURVIVE EPIRB ALERT SART LOCATE

Slide 2 · MARITIME KNOWLEDGE

MARITIME KNOWLEDGE FOR A SAFER TOMORROW GMDSS ESSENTIALS EPIRB Emergency Position Indicating Radio Beacon THE DISTRESS ALERT Your primary float free distress alerting device. It transmits a distress alert through the Cospas Sarsat system, even if the bridge is gone. COSPAS SARSAT GLOBAL COVERAGE 406 MHz Distress alert 121.5 MHz Homing signal GNSS Position information (modern units) MEOSAR / RLS Enhanced capability (where supported) EPIRB 406 MHz HOW IT WORKS Transmits on 406 MHz to Cospas Sarsat satellites. Also transmits a 121.5 MHz homing signal for SAR aircraft and rescue units. Modern units may incorporate GNSS for position information. Newer beacon capabilities may include enhanced MEOSAR / Return Link Service functions where supported. SAR EXAM POINTS 48 HOURS Minimum operating duration FLOAT FREE Automatically releases and water activates (Category I) TESTING Routine inspection as per applicable requirements. Annual testing under SOLAS requirements. 5 YEARS Shore based maintenance at intervals not exceeding 5 years (subject to requirements). KEY RULE Once activated, leave it ON until rescued. Small Device Big Difference

Slide 3 · MARITIME KNOWLEDGE

MARITIME KNOWLEDGE FOR A SAFER TOMORROW Be Seen Be Rescued GMDSS ESSENTIALS SART Search and Rescue Transponder THE SEARCH LOCATOR A radar based locating beacon. While the EPIRB tells the world you are in distress, the SART lets a searching ship's or aircraft's radar see you among the waves and clutter. SART SEARCH AND RESCUE TRANSPONDER OPERATES ON 9 GHz (X-BAND) HOW IT WORKS • When interrogated by a searching radar, the SART responds with a distinctive signal on the radar screen. • Signal appearance: 12 DOTS (Far range) 12 ARCS (Closing range) CONCENTRIC CIRCLES (Very close range) RANGE 6 NM RINGS 1 NM X-BAND SART Helps rescuers determine the direction and approximate range to your position. EXAM POINTS FREQUENCY 9 GHz (X-Band radar) RANGE ~ 5 NM (to a ship with 15 m antenna height) ~ 30 NM (to an aircraft under specified conditions) BATTERY CAPABILITY 96 hours standby 8 hours continuous interrogation TESTING Routine testing should follow the applicable Administration, approved servicing requirements and manufacturer's instructions. AIS-SART Broadcasts its distress position information using AIS to suitably equipped receiving stations. Small Device Big Impact

Slide 4 · MARITIME KNOWLEDGE FOR A SAFER TOMORROW

Prepared People Survive SURVIVAL ESSENTIALS SURVIVE THE IMMEDIATE DANGER DIFFERENT THREATS. DIFFERENT PROTECTION. IMMERSION SUIT EEBD PROTECTION FROM HYPOTHERMIA EMERGENCY ESCAPE BREATHING DEVICE Designed to reduce rapid body heat loss in cold water and give you more time for rescue. ESCAPE ONLY Designed for emergency escape from smoke or dangerous atmospheres. Watertight and thermally protective Integral hood, boots and gloves (as applicable) Retro reflective material and whistle Designed for rapid donning Donning within 2 minutes (as per requirements) SailR EEBD Minimum service duration: 10 minutes Hood or suitable face covering arrangement (depending on approved design) Follow the manufacturer's activation and donning procedure. DO NOT USE EEBD FOR Firefighting Re entry into dangerous spaces Tank entry Prolonged rescue or work REMEMBER The immersion suit provides thermal protection. A lifejacket provides buoyancy where required. RIGHT EQUIPMENT. MORE TIME. A SAFER YOU. Same Goal A Safer Tomorrow

Emergency Position Indicating Radio Beacon Primary role Send a distress alert to the world with your position. When it's used Once you have abandoned ship (or mustered at the lifeboat) and are in distress.
