Useful insights

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

Fireball occurs only when instantaneously released pressurized liquefied 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.

Due to the two-phase nature of the release, a Pool Fire may arise from the corresponding liquid spill when direct ignition occurs.
