The at least one fall detect node is to be implemented as part of a fall protection system. The at least one fall detect node includes at least one detection element and a node transmitter. The at least one detection element is to generate an activation signal upon a condition that indicates a fall event has occurred. The node transmitter is to transmit at least one fall detect signal upon receiving the activation signal from the at least one detection element. The personal communication application is stored in a personal communication device. The personal communication application is to cause the personal communication device to monitor for the fall detect signal and cause the personal communication device to communicate with a remote communication device upon determination that a fall event has occurred. ## Claims ### Claim 1 A system comprising: a fall protection harness configured with a fall detect node, wherein the fall protection harness is configured to be worn by a worker and arrest a fall of the worker during a fall event, and wherein the fall detect node is configured to transmit a first, fall detect signal in response to the fall of the worker;
