In which locations on the E-190 is chemical oxygen supplied?

• A. Cabin and LAVs
• B. Flight Deck only
• C. Cabin only
• D. LAVs only

Answer: (A)

Oxygen systems on airliners are designed to provide breathable air to occupants during a loss of cabin pressurization. On the E-190, the chemical oxygen generators are installed in two areas that need immediate, self-contained supply for passengers and crew: the cabin and the lavatories. When depressurization occurs, oxygen masks for passengers deploy from overhead panels in the cabin, and those masks are powered by chemical generators located in that area. Lavatories also have their own oxygen supply arrangements to ensure occupants there have access to oxygen as needed. The flight deck has its own dedicated oxygen supply that’s separate from these cabin and lavatory generators. This means the chemical oxygen produced by the generators in the cabin and lavatories is specifically for those spaces, while the pilots’ oxygen comes from a different source. Hence, the locations supplied by chemical oxygen are the cabin and the lavatories.
