Explosive Gas (Fallout: New Vegas)

Explosive Gas is a trap

Gameplay
Gas leaks are areas that have filled with natural gases that ignite if any sort of combustion occurs within the area of the leak. They are usually found in tunnels and can be visually detected by noting a wavering distortion in the air.

When a gas leak is ignited, anything in the immediate vicinity takes a small amount of damage, is set on fire, and is knocked down for a few seconds. Some gas leaks can be removed by taking away their source, this is often a leaking valve. Using open flame weapons will also trigger the trap.

Locations
Explosive gas occurs in a number of places like the kitchen of the Cantina Madrid and the suites in the Sierra Madre Casino & Resort in Dead Money and Vault 34 of the Mojave Wasteland.

Related quests
A variation of this type of trap is used as an optional component of the quest There Stands the Grass. In this instance, the Courier is asked to deliberately ignite explosive gas which now fills the entirety of Vault 22.
