Portable Individual Rescue Breathing Gear (PIRBG) forms part of the General-Purpose Individual Rescue Kit (GPIRK).
PIRBG is designed to provide breathing of crew members and passengers during unassisted rescue from a ditched or sunken aircraft.
PIRBG allows breathing under water at a depth of up to 30 metres for 1.5 minutes (submersion – 30 seconds, being at the depth – 20 seconds, surfacing – 40 seconds), with pulmonary ventilation of up to 30 litres per minute. In addition, PIRBG can be used by divers as a spare respiratory apparatus.
The gear consists of:
- breathing valve with a mouthpiece and nose clip;
- compressed-air bottle;
- suspension and fixation system to attach the gear to the user’s body.
