Timeline of Physics at Work

1 – 25 ms

Pressure rise from a deflagration opens the explosion vent allowing the dust and flame to enter the flameless vent

2 – 90 ms

The flame from the deflagration makes contact with the flameless vent mesh and the quenching process begins

3 – 200 ms

The deflagration is fully quenched and begins to contract as pressure is relieved and flame is retained

4 – 500 ms

As the hot gases cool the flameless vent allows cool air to flow and the explosion is mitigated safely
