A safety circuit for a Personal Alert Safety System (PASS) device includes a safety logic circuit and an alarm circuit. The safety logic circuit is communicably coupled to the PASS device. The safety logic circuit includes a timer configured to determine a time elapsed since the timer has been last reset. The safety logic circuit is configured to switch from an off state to an on state upon receiving an activation signal from the PASS device and reset the timer upon switching to the on state, generate a trigger signal in response to the timer exceeding a time threshold, and reset the timer upon receiving a reset signal from the PASS device before the timer exceeds the time threshold. The alarm circuit is communicably coupled to the safety logic circuit and configured to generate an alarm signal upon receiving the trigger signal from the safety logic circuit.

Safety circuit, device and method

A system, wearable device and management device provided for predicting a flashover event. According to one aspect of the disclosure, a wearable device for predicting a flashover event is provided. The wearable device includes at least one thermal sensor configured to generate thermal data associated with an environment, and processing circuitry configured to: determine a risk of ignition of at least one combustible gas in the environment based on the thermal data, and trigger at least one action based on the determined risk of ignition.

System and method for risk classification and warning of flashover events

A monitoring unit for wireless communication with a plurality of self-contained breathing apparatus (SCBA) units configured to form a network is provided. The monitoring unit includes a communication interface and processing circuitry. The processing circuitry is configured to receive, via the communication interface, a plurality of updates from each of the SCBA units where each update includes information indicating at least one communication link quality to at least one other SCBA unit. The processing circuitry is further configured to determine at least one distance from each SCBA unit to at least one other SCBA unit that is one hop away in the network based at least in part on the communication link quality. The processing circuitry is further configured to cause the determined at least one distance to be displayed.
