Approaches  to  creation  of  gas  safety  systems  for  industrial  and  residential  buildings  are  presented.  The  necessity  of applying the technical means of early detection of natural gas leaks and round-the-clock control of gas contamination of industrial and residential buildings is shown. An example of a pilot project for introduction of a gas monitoring system for methane  is  described,  which  demonstrated  the  possibility  of  providing  highly  effective  protection  of  population  against man-made emergencies caused by accidents in gas supply networks that revealed the technological problem of difficulty of installation of wire lines for distributed gas monitoring system. The ideology, architecture and technical solutions for the scientific and technical problem of creation a wireless gas safety system for territorially distributed industrial and residential facilities are presented on the basis of a unique gas sensor with ultra-low energy consumption based on optoelectronic devices of middle infrared range. The consistency of the approach developed by the authors in creation of wireless gas contamination control systems is proved.
