In the early hours of the morning you notice lights out at sea, it must be a ship! What should you do?
Answer Fire off a parachute signal flare from your life raft survival kit.
Red parachute flares are an international distress signal. They can reach up to 1,000ft high in the air and will slowly drift back down to the ground burning for roughly 40 seconds. The reason that this is most effective is that it can be fired in a matter of seconds, you can aim it in the direction of your choosing, and it is visible up to 36 miles away!
