Buoyant Smoke Orange The orange buoyant smoke is a daylight signal flare that can be used on ships, lifeboats and life rafts. This smoke signal emits a dense orange smoke visible from boats several kilometres away. It also provides a great visibility for search and rescue helicopters and airplanes. The case is made of corrosion-resistant steel and carries clear and simple instructions, making the emergency signal very easy to use. To activate it, simply remove the lid, pull the internal loop and throw it into the water. It will immediately emit emergency smoke to attract attention. The orange buoyant smoke signal has been approved globally and meets the latest SOLAS regulations.
