Buoyant Smoke Flare

A floating pyrotechnic device that emits dense, orange coloured smoke to signal distress or indicate position at sea. 

A buoyant smoke flare is an essential piece of marine safety equipment designed for use in emergency situations. It is typically housed in a waterproof, buoyant casing that allows it to float on the water’s surface while producing a thick, highly visible smoke plume. These flares are commonly used for daytime distress signalling, as the smoke can be seen from a considerable distance, aiding in search and rescue operations. 

Buoyant smoke flares are activated by pulling a tab or removing a cap and igniting the device, which then releases smoke for a specified duration, often between three to five minutes. The smoke is usually orange, as this colour provides high contrast against the sea and sky, making it easily distinguishable. 

These flares are carried on lifeboats, life rafts, and larger vessels as part of their mandatory safety equipment. They are particularly useful in situations where a vessel is disabled or a person is in the water, as they provide a clear visual marker for rescuers. Unlike handheld flares, buoyant smoke flares do not require the user to hold them, allowing them to function effectively even in rough sea conditions.
