摘要

PURPOSE: To supply respiration air for an emergency rescue as quick as possible by shifting from the water supply to the supply of respiration air for an emergency rescue to personnel confined in a burning toxic-gas-filled building and used up the air from their portable respiration source normally being carried around, and by shifting the standard fire extinguishing hoses to such, as easily and quickly as possible. CONSTITUTION: The respiration air supply assembly for an emergency rescue 21 is uniquely designed so that the respiration air is continuously supplied into the fire extinguishing hoses 18 from the air supply tanks 39, 40 and that the check valves 31, 32 are positioned/installed between the entrance of a T-joint 29 and the tank air supply hoses 35, 26 each connected to the air supply tanks 39, 40. For use, the shut valve 43 is opened on the top of the tank 39 to draw the air from the tank into the hose 35, which then passes through the check valve 31 to enter into the hose 28, thus, flowing down into the adjuster 24. There, the air passes through a quick coupler assembly 20 connected to the air for an emergency rescue to enter into the fire extinguishing hose 18, thus, supplying the respiration air for an emergency rescue of personnel confined inside.
