Perhaps you mean explosive depressurization.
No...this time I think he said what he meant:


Uncontrolled decompression is an unplanned drop in the pressure of a sealed system, such as an aircraft cabin, and typically results from human error, material fatigue, engineering failure, or impact, causing a pressure vessel to vent into its lower-pressure surroundings or fail to pressurize at all.
Such decompression may be classed as Explosive, Rapid or Slow:
Explosive decompression (ED) is violent, the decompression being too fast for air to safely escape from the lungs.
Rapid decompression, while still fast, is slow enough to allow the lungs to vent.
Slow or gradual decompression occurs so slowly that it may not be sensed before hypoxia sets in.
The Federal Aviation Administration recognizes three distinct types of decompression events in aircraft:
Explosive decompression

Rapid decompression
Gradual decompression
JNB - I find it very hard to believe that these are really your thoughts and depth of knowledge of the program.
