The explosive decompression that killed Lieutenant Branson


An airlock on the USS Voyager undergoing explosive decompression

Explosive decompression is a violent, sudden drop in ambient air pressure that occurs within one tenth of a second when in space.

Opening, disabling, or the failure of the containment fields around airlocks and external hatches, such as those found in shuttlebays and cargo bays, or a major hull breach while in any environment of substantially lower pressure, will result in an explosive decompression. Decompressing the main shuttlebay aboard a Galaxy-class starship would cause a reaction sufficient enough to move the ship. (TNG: "Contagion", "Disaster", "Cause and Effect")

In 2154, Enterprise NX-01 lost several crew members, including Jane Taylor, to an explosive decompression during the Battle of Azati Prime. (ENT: "Azati Prime")

In 2233 of the alternate reality, at least one USS Kelvin officer was blown into space through a hull breach during a battle with the Narada. (Star Trek)

In 2259, Montgomery Scott opened an airlock aboard the USS Vengeance to allow access for James T. Kirk and Khan Noonien Singh. A Section 31 security officer was blown into space as a result. (Star Trek Into Darkness)

In 2364, the bridge crew of the SS Tsiolkovsky, suffering from polywater intoxication, opened an emergency hatch and was blown out into space. (TNG: "The Naked Now")

In 2367, the USS Enterprise-D attempted to remove Junior from its dorsal section by depressurizing Shuttlebay 2. The explosive decompression failed to dislodge the alien baby though. (TNG: "Galaxy's Child")

In 2368, the USS Enterprise-D decompressed its main shuttlebay in order to avoid a collision with the USS Bozeman. (TNG: "Cause and Effect")

One of Dukat's duties, when he was a Glinn serving aboard the Cardassian starship Kornaire, was to clean out a compartment where three men had been killed by explosive decompression. In 2374, told Benjamin Sisko that "I didn't sleep for a week after that". (DS9: "Waltz")

In 2372, USS Voyager experienced an explosive decompression on deck 15 which killed Ensign Harry Kim. (VOY: "Deadlock")

While in command of Voyager in 2374, Chakotay ordered an explosive decompression to kill the Borg in Cargo Bay 2. One drone, Seven of Nine, survived. (VOY: "Scorpion, Part II")

During the Battle of the Bassen Rift in 2379, the Reman warbird Scimitar launched a volley of photon torpedoes at the USS Enterprise-E's bridge, resulting in an explosive decompression which killed Lieutenant Branson. (Star Trek Nemesis)
