About this app

Red Line Safety brings real-time situational awareness to firefighter teams. Monitor your crew, track positions, and recognize risk earlier — so every firefighter goes home.

Built on Red Line Safety's IMSAFE concept of Incident Management Situational Awareness, this app gives incident leaders and crews a live operational picture while they work.

CREW MONITORING
- Live status of every firefighter on scene
- Biometric and motion data from body-worn devices
- Position tracking on incident maps
- Physiological insight into stress, exertion, and recovery

INSTANT ALERTS
- Down-firefighter detection
- Situational awareness across the incident
- Custom alert thresholds for your team

BUILT FOR THE FIRE SERVICE
- Designed alongside working fire departments
- Works with Red Line Safety body-worn and deployable hardware
- Built on the Nexus platform

Biometric monitoring isn't about oversight — it's about empowerment, awareness, and making sure firefighters go home.

DEVICE COMPATIBILITY
Red Line Safety is a companion app for Red Line Safety body-worn and deployable hardware. It requires a paired Red Line Safety device to function and is intended for use by fire departments and authorized Red Line Safety customers. Heart rate, motion, and location data are read from the paired Red Line Safety hardware and from the Android device's built-in GPS and motion sensors. Any Android device running Android 10 or newer with Bluetooth Low Energy (BLE) and GPS is supported. Contact your Red Line Safety representative for hardware and account provisioning.

IMPORTANT — NOT A MEDICAL DEVICE
Red Line Safety is not a medical device. It is an occupational situational-awareness tool for fire service use. It is not intended to diagnose, treat, cure, mitigate, or prevent any disease or medical condition, and it must not be used as a substitute for professional medical advice, diagnosis, or treatment. Heart rate, motion, and location information shown in the app are operational indicators for incident command and crew awareness, not clinical measurements. Always rely on trained medical personnel and established emergency protocols for any medical decision.
