Abstract: Fire hazard is a physical hazard in industries that are taking lives more than ever because of the lack of Fire Alert and Rescue Navigation systems (FARNS). Fire disasters are becoming more and more troublesome day by day in industries. People are dying in high-storied buildings and industry sectors due to fire hazards. IoT and OpenCV can bring new aspects to Fire Alert and Rescue Navigation systems. The OpenCV-Based Fire Rescue Navigator System can be used to locate the location of the fire hazard and deliver emergency fire alerts via online and offline channels. Contrary to expectations, firefighters can quickly and easily reach the affected area and save lives. A reliable fire rescue navigation system and monitoring solution are essential to our industry. Our system presented an insurmountable way to rescue fire occupants utilizing an OpenCV-based Fire rescue navigation system which can also overcome internet and power outages in devastating fire hazard situations.
