depressurize
Let air escape
To depressurize is to release or reduce pressure in an enclosed space.
Aircraft cabins depressurize when seals fail at high altitude—a dangerous emergency.
Divers must depressurize gradually when ascending to avoid decompression sickness.
The term applies to any sealed system: The technician depressurized the tank before opening it.
