An explosive decompression occurs within how many seconds?

1-10 seconds 10 seconds or longer 5 seconds Less than 1 second

Correct Answer:

Less than 1 second

Explanation:

An explosive decompression happens when cabin pressure is lost in effectively an instant—within less than one second. That ultra-rapid drop creates a sudden and large pressure differential, causing immediate effects on people and the aircraft structure, and it requires instant crew action, including donning oxygen and securing oneself. This is what separates explosive decompression from rapid decompression, which occurs more gradually over about one to ten seconds. So, the correct time frame is less than one second; the other options describe slower decompression that doesn’t fit the explosive category.
