AUTOMATED SYSTEM OF SAFETY MANAGEMENT WHILE WORKING AT FIRES IN THE ATMOSPHERE UNSUITABLE FOR BREATHING
PURPOSE. The article offers improvement of automated system of firefighters safety management while working at fires in the atmosphere unsuitable for breathing taking into account specific character of digital processing safety management results. METHODS. In order to achieve the assigned goal we have used the risk management theory and the probability model of safety management developed on the basis of this theory. Applying the probability model of safety management in comparison with the deterministic model allows us to vary interval safety criteria values and simultaneously use their normal and actual characteristics. FINDINGS. We have suggested model hierarchy structure of automated management system considering probability structure of the results of direct numerous measurements of absolute pressure values in the breathing apparatus cylinder of a firefighter. There has been conducted a risk analysis of the destructive event occurrence connected with the lack of air in the breathing apparatus cylinder for successful and safe realization of works in the atmosphere unsuitable for breathing. RESEARCH APPLICATION FIELD. The research results are intended for officials of emergency- rescue and fire-rescue teams whose duties include solving the problem of ensuring safety during works in conditions when the atmosphere unsuitable for breathing affects the participants of fire extinguishment process. CONCLUSIONS. We have suggested the structure of the formalized procedure of probability evaluating safety criteria taking into account the realization risk of the considered destructive event. On the basis of theoretical results the automated management system of safety of fire extinguishment participants at works in the atmosphere unsuitable for breathing has been developed.
