The Emergency Position Indicating Radio Beacon (EPIRB) is a crucial piece of safety equipment for vessels, transmitting distress signals in the event of an emergency. Regular testing of the EPIRB ensures that it functions correctly and is able to send distress signals in the event of a disaster. Testing includes checking the battery, antenna, and signal strength. Regular EPIRB testing is vital to ensure that the vessel complies with SOLAS requirements and can effectively communicate distress messages to rescue teams, increasing the chances of timely assistance during emergencies.
