Useful insights

All instantaneous gas releases are always accompanied by a Gas Blast, which is an overpressure effect occurring regardless of ignition or confinement.

Fireball occurs only when instantaneously released gas is directly ignited.

If the flammable cloud first disperses but can ignite later, a Flash Fire might occur.

Every time flammable mass is confined, a Vapour Cloud Explosion (VCE) may occur.

Jet fire needs momentum and, therefore only results from the direct ignition of continuous releases.
