Short summary
Tracer gas experiments demonstrate possible pathways of toxic gas propagation, especially in subsurface infrastructures like subway stations. Precise gas sensors are needed to record the concentration levels over time; thereby, a better understanding of how smoke or toxic gas affected evacuation routes can be achieved. The acquired knowledge can be used to optimize evacuation and reaction plans and might reduce the casualties in catastrophic circumstances.
