Loss Prevention Advice

A guidance regarding the registration of distress alert devices and the procedures for cancelling false distress alerts.

As explained by the US Coast Guard, accurate registration and prompt cancellation of false distress alerts are crucial for maintaining maritime safety, ensuring search and rescue resources are used efficiently, and preventing unnecessary disruptions. According to National Oceanic and Atmospheric Administration’s Incident History Database (IHDB), the chart below depicts the number of distress alerts vs. false alerts that occurred from 2020-2024 from distress alert devices: 

Registration of distress alert devices

Distress alert devices, such as EPIRBs (406 MHz satellite Emergency Position-Indicating Radio Beacon), PLBs (Personal Locator Beacons), SARTs (Search and Rescue Transponders), Digital Selective Calling (DSC) with a Maritime Mobile Service Identity (MMSI) number for marine radios, and Inmarsat ship earth stations are essential tools for distress signalling.

The registration of these devices is a critical step to ensure effective and rapid rescue in an emergency. It is essential to keep registration details current, especially if your vessel changes ownership or your emergency contact details change. The below links provide additional information about registering distress alert devices:

• EPIRB, PLB & SART Registration: US Beacon Registration
• For MMSI on Marine Radios & Inmarsat: MMSI | Federal Communications Commission

For MMSI registration, it is highly encouraged to have a licensed FCC technician program the MMSI on your marine radios and Inmarsat, as these devices do not allow for correction to accidental entries. Remember that registration information should be available for verification by the Coast Guard Boarding Officers and Marine Inspectors and updated promptly after any major changes. Proper registration of your EPIRB is intended to save your life and is mandated by Federal Communications Commission (FCC) regulations. The Coast Guard is continuing to enforce the FCC registration rule.

Cancelling false distress alerts

False distress alerts, whether accidental or deliberate, can result in unnecessary deployments of search and rescue resources, potentially diverting attention from real emergencies. The main reasons for false alerts include beacon mishandling or malfunction, mounting failures, environmental conditions, improper disposal, or accidentally pressing the DSC button on your marine radio or Inmarsat. While not all false alerts can be prevented, it is critically important to cancel an alert if you know it is accidental or unintentional. The procedures for cancelling false distress alerts are found in the Federal Communications Commission regulations (Title 47 Code of Federal Regulations 80.335). The following link will take you to this regulation, which gives step-by-step instructions on what to do for the distress alert devices listed above:

In the event of an accidental distress alert, it is vital to ensure that contact information in the distress device registration is up to date. If a Rescue Coordination Center is unable to reach a representative for the vessel, it will result in the unnecessary launching of resources, whether federal, state, or local.

If your company or vessel utilizes a Safety Management System or a Towing Safety Management System, it is highly encouraged to incorporate these procedures to ensure compliance with the regulations.
