in flight what is the most dangerous type of decompression
Pressurized Aircraft (Part Three) Decompression. Explosive decompressionâa change in cabin pressure faster than the lungs can decompress, possibly causing lung damage. Normally, the time required to release air from the lungs without restrictions, such as masks, is 0.2 seconds. Most authorities consider any decompression that occurs in less than 0.5 seconds to be explosive and potentially dangerous.
