What does the international distress frequency of 2182 kHz signify?

The international distress frequency of 2182 kHz is designated as a mandatory frequency for distress communication on medium frequency. This frequency is crucial for maritime safety as it is specifically reserved for distress calls, emergency communications, and urgent safety information.

Maritime regulations, established by the International Telecommunication Union (ITU) and the International Maritime Organization (IMO), dictate that all ships at sea must monitor this frequency, ensuring that any distress signal can be communicated effectively and responded to swiftly. The use of 2182 kHz allows for clear and reliable communication in emergencies, making it essential for safety at sea.

While other options may describe different uses of maritime communication frequencies, none match the dedicated purpose of 2182 kHz for distress signals, which is vital in emergency situations.
