When will a float-free EPIRB be activated after abandoning ship?

The float-free EPIRB (Emergency Position Indicating Radio Beacon) is designed to automatically activate as soon as it becomes free-floating in water. This feature is critical for ensuring timely distress signaling in emergencies when a vessel is abandoned.

The immediate activation upon floating free allows the EPIRB to begin transmitting a distress signal without delay, increasing the chance of a swift response from rescue services. Being ready to send location information as soon as it is released from its mounting system is essential for search and rescue operations, as it aids in locating individuals in distress as quickly as possible.

The other options imply various delays in activation, which are not consistent with the functioning of float-free EPIRBs. By activating immediately upon floating free, these devices fulfill their purpose of enhancing safety during maritime emergencies.
