The incident commander needs live information from all BA wearers at all entry points and to know they are accounted for in any scenario.
The FireGround App as part of FireGround Accountability system accomplishes this in a rapidly deployable mode and minimises the need for voice communication via radio.

Minimum effort for firefighters on scene, the system automatically informs the monitoring person of any alerts or important changes.
System supports Motionless Alerts (Automatic Distress signal), manual distress alerts and more.
App users can send evacuation alarms to all BA wearers, in case a dangerous situation arises.
Reduces the need for verbal status updates as the continuous data exchange between SCBA and FireGround keeps everything updated.
