Every year valuable resources are wasted in locating EPIRBs which have been activated inadvertently. Masters and Officers need to be aware that even a single burst from a 406 MHz EPIRB can be detected instantaneously by the Cospas–Sarsat GEOSAR system which will result in an RCC being alerted. As to US Coast Guard report: 96% 406 MHz EPIRB Alerts are false.
Should it be suspected that an EPIRB has been activated inadvertently, the Master or person responsible for the vessel must immediately advise the MRCC for their area of operation.
