Marine smoke signal is a necessary survival signal in lifeboats and rafts. It can float on the water and emit orange-yellow smoke signal fireworks. This type of product is approved by the Ship Inspection Bureau of the People's Republic of China and meets the requirements of the 1983 amendment to the 1974 Safety of Life at Sea Convention.
The orange-yellow smoke signal is mainly used for visual discovery during the day. When the smoke signal is activated, the strong smoke is convenient for passing aircraft or ships passing by at close range to find people in distress at sea. The signals are marked with instructions for use and concise illustrations, and should be operated in accordance with the specified requirements when using them.
Both sides of the ship's bridge are equipped with life-saving coils with smoke signals and lights. When the ship suddenly falls into the water during the voyage, the bridge-keeper should immediately drop the life-saving coils with smoke and lights on the side of the person falling into the water. Using its smoke and lights is convenient for ship watchers to find targets and search and rescue people overboard.
Finally, a friendly reminder that the performance requirements for smoke signal bombs are as follows:
(1) Evenly spray out bright and easy to see color (usually orange-yellow) smoke, and the duration is not less than 3min.
(2) It will not be submerged in sea waves. After being immersed in 100mm deep water for 10s, it can still emit smoke.
The above is the relevant knowledge of the orange smoke signal for ships compiled for you. I hope to help you understand some small knowledge about ship travel safety.
