FIELD: machine engineering.
SUBSTANCE: device comprises a system of sensors and an electric valve, in addition, there is a protected object, which is required to be transferred from normal operation mode to the emergency mode due to hazard of emergency situation development, and which is connected to an actuating device, which is triggered by signal from a control device made in the form of electric valve. The electric valve is connected to a system for probing a hazardous zone, including sensors configured to exceed the maximum permissible concentrations of chemically hazardous substances present in this zone, and a probe tuned to exceed the maximum permissible levels of radioactive substances, the signals from which are fed to a common microprocessor, which processes these signals and gives a control signal to turn on the electric valve. A chemical air-foam fire extinguisher placed on a platform equipped with rotation mechanisms around the axis of the fire extinguisher, and configured for its vertical movement, while the operation of these mechanisms is synchronized with an infrared sensor. The chemical foam generator of the air-foam fire extinguisher contains a hollow body consisting of a cylindrical part with an external thread for connection to the union of the distributing pipeline for liquid supply.
EFFECT: increased efficiency of process equipment protection against emergencies by improved performance and reliability of system activation.
