Performing a fire and rescue operation in a tunnel or an underground construction represents a challenging task in a complex environment. This paper discusses these challenges from a technology support perspective. The possibilities – and challenges – with new emerging technology is highlighted and discussed. This paper is highlighting the challenges with fire and rescue services moving speed in smoke-filled tunnel environments, with or without the support of new technology as well as how new technologies affect the fire and rescue operation at large. The technology discussed is mainly represented by wearable technology that can be used during a fire and rescue operation in order to increase the moving speed of the BA firefighters, to make the fire and rescue operation safer or technology that supports the task by making the fire and rescue operation more effective. The comparisons regarding the moving speed of the BA firefighters are made based on earlier performed tests both with real fires and tests where the visibility is obstructed by cold smoke. Finally, the paper discusses how these new emerging technologies can support the Incident Commander regarding decision making and surveillance. The paper also highlights the challenges with implementation of such technology and a brief overview of the need of emerging technologies.
