explosive decompression

[ik′splō·siv ‚dē·kəm′presh·ən]
(aerospace engineering)
A sudden loss of pressure in a pressurized cabin, cockpit, or the like, so rapid as to be explosive, as when punctured by gunfire.

explosive decompression

A sudden decrease in the cabin pressure, which may be the result of either some component of the aircraft, like door(s), window, or cockpit canopy, etc. giving way or of a rupture taking place in the structure. As soon as this decompression takes place, the equipment and the personnel tend to be sucked out and the personnel may suffer decompression sickness. Similar to but faster than rapid decompression.

The increase in both operating temperature and pressure of the R134A has created problems with the elastomers in both thermal stability and explosive decompression in elastomeric seal boots, orings and hose liners.
Explosive decompression typically occurs when a gas is absorbed by an o-ring while operating in high pressure; the gas is trapped within the o-ring when the system pressure drops, causing the surface of the o-ring to blister and rupture as the trapped gas expands.
With regard to rubber products, there has been a significant amount of work done in the last few years with respect to explosive decompression in products used in the oil field and with improving the life of tank treads.
It is of utmost importance that elastomer formulations be optimized for resistance to explosive decompression.
