How to escape from capsize
|
Activate PML
Remove pfd temporoary escape toward bow order of escape, best, worst better use line to guide others out |
|
PFD Only temps
|
Air + 60, water + 50
Otherwise anti exposure suits, or dry suits and layer 1+2 |

Transmitting a spoken voice Pan-pan, or a Mayday message by radio over very high frequency (shorter range VHF) channel 16 (156.8 MHz) and/or high frequency (longer range HF) on 2182 kHz
Transmitting a digital distress signal by activating (or pressing) the distress button (or key) on a marine radio equipped with Digital Selective Calling (DSC) over the VHF (channel 70) and/or HF frequency bands. Transmitting a digital distress signal by activating (or pressing) the distress button (or key) on a Inmarsat-C satellite internet device Sending the Morse code group SOS by light flashes or sounds Burning a red flare (either hand-held or aerial parachute flare) Emitting orange smoke from a canister Showing flames on the vessel (as from a burning tar barrel, oil barrel, etc.) Raising and lowering slowly and repeatedly both arms outstretched to each side Making a continuous sound with any fog-signalling apparatus Firing a gun or other explosive signal at intervals of about a minute Flying the international maritime signal flags NC Displaying a visual signal consisting of a square flag having above or below it a ball or anything resembling a ball (round or circular in appearance) Launching distress rockets |
