Quick Answer
A whistle for ocean emergencies is a crucial safety tool that can save lives. It's an inexpensive and lightweight device that can be easily carried in your life jacket or attached to your clothing. In a distress situation, a whistle is one of the most effective ways to signal for help.
Choosing the Right Whistle
When selecting a whistle for ocean emergencies, look for a device that meets international safety standards. The International Organization for Standardization (ISO) has set a standard for whistles used in emergency situations, which is a sound level of at least 104 decibels. A whistle that meets this standard can be heard from a distance of up to 1 mile (1.6 kilometers) in calm conditions. Consider a pealess whistle, which is more durable and resistant to corrosion than traditional pea whistles.
Signaling Techniques
To maximize the effectiveness of your whistle, learn the proper signaling techniques. The International Safety at Sea Code recommends using the following signals: three short blasts on the whistle (one second each) to signal “person in distress,” and six blasts to signal “require assistance.” Signal in short bursts, with a 3-5 second interval between each burst. This will help prevent your signal from being mistaken for other sounds, such as seagulls or ship engines.
