redningsfløyter
Redningsfløyter are compact signaling devices used to attract attention in emergencies at sea or on land. They are commonly fitted to life jackets, lifeboats, rafts, and other safety gear, and may also be carried separately by walkers, hikers and climbers. The primary purpose is to produce a loud, piercing sound that can be heard over wind, waves, and background noise, enabling responders to locate a person in distress or to alert nearby vessels.
Most rescue whistles are pea whistles, which use a small ball (the pea) to create a trill
Usage and signaling patterns: A whistle is typically blown by short bursts or notes to maximize distance
Regulatory and practical notes: In many countries, a whistle is a recommended or required item on personal
Maintenance and care: Keep the whistle dry and free of obstructions; rinse salt after exposure and inspect
