The paper presents an experimental system enabling a laboratory simulation of several types of critical situations and aggravating
circumstances (sources of smoke, fog, rain, heat) using a thermovision equipment. The critical situations taken into consideration
are those caused by human negligence or natural disasters such as earthquakes. Aggravating circumstances are those considered as
being limit. The proposed thermovision equipment with appropriate accessories must highlight and determine the measures useful
in the such situations of risk. The acquired images are transmitted in real time and require using of special equipment which is
presented in the work, to observe the occurred phenomena. It is also analyzed in the paper the calibration of that equipment to allow
the selection of features and possibilities for adjusting of this thermovision system, to ensure optimum detection, warning,
management and the intervention as a risk event. The presented experimental results show the performance of the proposed system
and its possible future developments.
