Something that all veritable fliers will be intimate with in the pre - flight safety declaration is what to do with the oxygen mask .
" To set off the stream of O pull the mask lightly towards you . "
Sounds nice and simple , unless you ’re attempt to do that while a rapid decompression is taking place at over 30,000 feet in the strain .
A speedy decompression is an unplanned drop in the pressure of a sealed environment and can happen if the carpenter’s plane door is unfold mid - flight , or if a window is smashed . However , asThe Telegraphpoints out , the majority of these uncontrolled decompressions happen due to failures in the plane ’s structural integrity , or poor repairs .
But if the plane door was to open mid - flight , " anyone endure near the exit would be ejected into the sky ; the cabin temperature would quickly plummet to frostbite - inducing tier , and the plane itself might even set out to break apart,“airline pilotPatrick Smith tell The Telegraph .
During a rapid decompression at cruise altitude , most grownup will reportedly have between 15 to 20 second of utilitarian consciousness . That may sound like enough time to pull an oxygen mask towards you and peradventure even to assist the child next to you , but with rapid decompression , you have a great deal more to deal with .
A member of thePPRunE aviation forumnamed Superpilot depict what it is like for a pilot light to go through a rapid decompression : " Your tongue is swallow by your pharynx in a second , your ear begin to ache , and teeth become a hundred time more tender . ”
If you do n’t instantly pass out , one of the biggest risks is hypoxia , where the consistency is impoverish of atomic number 8 and will run to freak out , unconsciousness , lowering kernel rate , and eventually death .
This is why getting your O masquerade party sort as quickly as potential is the most authoritative matter you could do until the buffer is able-bodied to bring the woodworking plane to a breathable altitude .
However , nervous flyer need n’t worry too much .
As Jason Rabinowitz explained toTravel + Leisure , the pressure difference between the outside and inside makes it nigh on " physically impossible " to afford a door mid - flying , althoughthat has n’t stopped some people from tryingin the past times .
Smith says : " At a distinctive cruising EL , up to eight pounds of air pressure are pushing against every square inch of the [ aircraft body ] . "
As for the windows , they are contrive to withstand a monumental stage of pressure from the exterior and could easily outlast a human ’s force . They ’re made using a polycarbonate chemical compound with several stratum .
Ina note emerge by Airbus back in 2007 , the company warn that the air hose industry was unprepared and " untrained " for a decompressing consequence .
" In one cabin decompressing event , a cabin crew penis was saved from ejection out of the aircraft , because a rider was carry on to the cabin crew member ’s mortise joint . "
While these speedy decompression events are passing rare , it is always good to know what to do if one were to happen .
ensure your seat belt is fasten correctly , you know where the oxygen mask is going to dribble from , and where any vulnerable passengers are that may need your assistance once you are safe .
