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 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.
