Explosive Gas (Fallout 4)

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.
