What Is A Floating Smoke Signal?

The floating smoke signal is a kind of signal equipment used to call for help at sea. It is able to float on the surface of the water and continuously emit a prominent plume of smoke for passing ships or aircraft to spot and provide assistance.

A floating smoke signal usually consists of a metal or plastic cylinder containing the aerosol with an ignition device inside that can ignite the aerosol by pulling a pull ring or other means. Once ignited, the aerosol burns quickly and releases dense smoke, usually orange or white, which is very striking and can spread far over the sea.

The use of floating smoke signals is as simple as throwing them onto the surface of the sea. Because it can float on the water, it can keep the signal continuous even in the case of large winds and waves.

Floating smoke signals are also often equipped with self-lighting or other visual signaling devices to provide better warning at night or in poor visibility.
