Abstract: Methods and systems are provided for an alert system for reducing a risk of an adverse health event in a firefighter or first responder. In one example, the alert system may comprise a wearable sensor and an alerting device, where the alerting device may be operable to receive physiological and/or environmental data from the wearable sensor and where the alerting device may be further operable to issue an alert based on the received physiological and/or environmental data. In some examples, the alert may be a function of one or more personalized thresholds for evaluating a stress level of the firefighter or first responder. In some examples, the alert may be issued via multiple communication channels.
