15-20 min depending on the use
page 1.40.8
What is the passenger oxygen system is supplied by ?
individual chemical oxygen generators located at each Passenger Service Unit (PSU)
page 1.40.8

Four continuous flow masks are connected to each generator
page 1.40.8
how many oxygen masks are connected to each generator above each attendant station and in each lavatory ?
2
page 1.40.8
how is the passengers oxygen generator activate ?
by pulling at least of the masks attached to it
page 1.40.9
how long does the oxygen flows from the passengers oxygen generator ? can it be stopped once it start ?
12 min and it can’t be stopped
page 1.40.9
why is it not advised to use passenger oxygen with cabin altitude below 14,000 feet when smoke or an abnormal heat source is present ?
The use of passenger oxygen does not prevent the passengers from inhaling smoke. Air inhaled is a mixture of oxygen and cabin air.
