Abstract
The Scott Emergency Escape Breathing Device (EEBD) was evaluated for use in CF transport/passenger aircraft in providing smoke prevention during emergency situations and in preventing hypoxia in the event of a cabin decompression at high altitude. The device was tested initially in the laboratory to assess oxygen production in both ambient and high temperature environments. It was then evaluated, using human subjects for its ability to resist in-leakage of a challenge gas (e.g. smoke), and for its ability to provide a suitable atmosphere to sustain a human at altitude. Test results indicate that there was very little in-leakage provided that the neck seal was maintained; however, one subject with a very small neck experienced considerable in-leakage. The EEBD produced approximately 200 liters of oxygen during its 15 to 17 minutes of operation and maintained a 97% oxygen atmosphere inside the hood on a human subject performing moderate exercise.
