This article assesses the likelihood of an emergency during the operation of excessive pressure equipment. Emergency situations were developed and simulated, their consequences were evaluated. Sketch maps for the implementation of events on the terrain with radii of damage to people and infrastructure were plotted. Simulation of the emergency showed that in case of an explosion of a steam boiler, severe structural damage and complete destruction of a mobile steam unit are possible. Based on the simulation results, a technical solution is proposed aimed at preventing the explosion of a steam boiler due to the implementation of an automated shutdown of fuel and water supply by installing a pressure measurement sensor. The technical solution describes the algorithm of the proposed automation process and the operator’s actions in case of failure of safety valves and the operation of the pressure measurement sensor.
