Explosion Pentagon

Explosion Pentagon

Just like the fire triangle, which represents the flammability conditions (and of consequent explosion), for liquid and gaseous combustibles, it is common to refer to “the explosion pentagon” when it comes to dust as well as gases, vapours and mists.

The five conditions represented in the pentagon of the explosions, and necessary to create the conditions for an explosion are:

1. PRESENT OF COMBUSTIBLE DUST

2. PRESENCE OF A COMBUSTION AGENT IN THE ENVIRONMENT

3. PRESENCE OF AN IGNITION SOURCE

4. DELIMITED ENVIRONMENT

5. MIXING OF REAGENTS
