METHOD FOR ENVIRONMENTAL MONITORING OF CHEMICALLY HAZARDOUS OBJECTS Russian patent published in 2009 - IPC G01W1/00 

FIELD: physics; measurement.

SUBSTANCE: invention relates to environmental monitoring and may be used to monitor chemically hazardous objects. Concentrations of hazardous substances are determined in the working area, in sanitary-protection zone, in protective action zone and hazard zone of environment. The results obtained are compared with threshold limit values. If the results exceed the limit values, contamination area and destructive effects area are predicted according to meteorological conditions and volume of substance released. In case of threatening contingency forecast, mobile test laboratories, lidars, stationary control stations are adaptively engaged in real time in the said areas according to predicted hazard effect development for contingency decision making. Stationary control stations are arranged in triangular pattern and promptly determine coordinates of possible release of hazardous substances by cross-correlation of parameters (registration of contaminated cloud and blast shock wave) according to time of signal arrival at the control station. Possible release of hazardous substances is verified by registration of emergency measuring signals by all three stations.

EFFECT: improved efficiency of contingency location due to shorter time of contingency decision making in case of explosion at a chemically hazardous object.
