FIELD: construction; fanning.
SUBSTANCE: invention concerns area of premises air fanning with corrosive and an explosive medium at an emergency long absence of the electric power at the object in full isolation from a medium. The ventilating system of a premise with corrosive, explosive and fire hazard medium contains an air pipe and gas ejector, besides a source corrosive and explosive and fire hazard gas, for example, the block of oxygen generators is connected by the pipeline supplied with the cock with gas ejector, executed from an anticorrosive material, to which the collector of a stage of cylinders with the compressed nitrogen is connected by other pipeline, and the exit of ejector is connected by a junction pipe, on which the three-way cock is installed, with a ventilating system air pipe.
EFFECT: creation of a safe ventilating system of a premise with corrosive, explosive and fire hazard medium.
