What is explosive decompression on a plane?
Explosive decompression (ED) is violent and too fast for air to escape safely from the lungs and other air-filled cavities in the body such as the sinuses and eustachian tubes, typically resulting in severe to fatal barotrauma.
What would cause the aircraft to have a rapid Decompressurization?
If the cause of the decompression is a structural failure, failure of a window for example, there may be a risk of some crew or passengers being buffeted by strong winds, hit by debris, and extreme cold temperatures, or even of being sucked out of the aircraft – another reason for wearing a seat belt or harness …
What is aircraft de compression?
Decompression is defined as the inability of the aircraft’s pressurisation system to maintain its designed pressure schedule. Decompression can be caused by a malfunction of the system itself or by structural damage to the aircraft.
What should be done during decompression in flight?
In the case of decompression the immediate use of oxygen is critical. Therefore, the first actions to be performed by the cabin crew are: Immediately don the nearest oxygen mask • Sit down fasten your seat belt, or grasp a fixed object • Hold on.
What happens if a plane becomes depressurized?
When a cabin depressurizes, the percentage of oxygen in the air stays about the same, but the molecules get further and further apart, Padfield explained. Then the air expands through an expansion turbine that cools air in the same way you can cool air by blowing it out of puckered lips.
How many people have died from explosive decompression?
It was registered in Hamilton, Bermuda. The rig has suffered some serious accidents, most notably an explosive decompression in 1983 that killed four divers and one dive tender, and badly injured another dive tender….Byford Dolphin.

What happen if aircraft pressurization fails?
The reduction in air pressure reduces the flow of oxygen across lung tissue and into the human bloodstream. Above 20,000 ft, lack of oxygen leads to loss of intellectual ability followed by unconsciousness and eventually respiratory and heart failure.
Why do planes depressurize?
A lot of the time when a plane suddenly depressurizes, it’s because some kind of damage has occurred and the airtight seal keeping the pressure inside the aircraft is broken.
What do you do for rapid decompression?
When rapid decompression occurs, your oxygen mask should drop from overhead. Put it over your mouth and nose, slip the straps over your head, then tighten them by pulling their ends. Breathe into the mask normally. The mask’s bag might not inflate, or inflate only while you’re exhaling.
Can you fly with decompression sickness?
Even if you are flying a pressurized aircraft, altitude DCS can occur as a result of sudden loss of cabin pressure (inflight rapid decompression). Following exposure to an inflight rapid decompressions do not fly for at least 24 hrs. Allow at least 24 hrs. to elapse between SCUBA diving and flying.
