A Contribution to Detection of Humans Located in Closed Areas

Abstract:

This paper deals with a detection of persons in closed areas. After a brief overview and providing a background the author focuses on the latest tools, which are available and on two examples explains the use of infrared spectrometry to arrive at the results. He points out the objectivity and rationality of the measuring outcomes as well as its commercial availability, simple control, relatively good price and the weight of the CO₂ measuring instruments. The method described in the article has been neglected and is not used in the present time for a detection of humans located in closed areas although it can be easily used for human detection in the fight against terrorism, organized crime, detection of hidden immigrants but also for searching the involuntarily trapped people (earthquake, avalanche), too. It is necessary to produce the bleeder probe for air taking from the closed space for the implementation of this method to the practice. It is also important to notice, that the closed object air could be polluted by the pollutants from the external environment (e. g. from exhalation from the fossil fuel burning) and from the exhalations, which can transpire from the interior material (e. g. phthalates, formaldehydes) as suggested in the article. That is why the author recommends dealing more with this topic, including a closer co-operation with car makers, research laboratories and medical organizations.
