METHOD AND DEVICE INDOORS LIVE-SAVING IN OUTDOOR AIR POLLUTION Russian patent published in 2010 - IPC A62B11/00 A62B13/00 

FIELD: medicine, fire fighting equipment.

SUBSTANCE: method of indoors live-saving in outdoor air pollution consists in enabling a starting device and feeding excess pressure pure air in a premise through a feed line. Before feeding, pure air is pre-charged in a high pressure tank. A device comprises an excess pressure pure air source connected with the premise through the feed line provided with the starting device. The feed line is equipped by a throttle; the air feed starting device represents a starting valve. The excess pressure pure air source consists of a main and at least one auxiliary part each of which presents at least one pre-charged high-pressure tank with a charging crane. The main part is connected with a feed line in front of the starting valve and the throttle. The auxiliary part is connected with a feed line before a throttle through its own starting valve. The life-saving device comprises a distributor to enable the starting valve of the auxiliary part of the pressure source after reducing air consumption in the premise to admissible value.

EFFECT: reduced time required to enable pure air feeding in the premise, and eliminated effect on increasing preparation time for wind intensity and direction feeding.
