What is an "Explosive Atmosphere"?
Classification of powders according to established parameters
Explosive powders are divided into 4 classes according to their Kst values. The explosion categories of powders according to their kst values are given in the table below.
| Explosion Class | Kst [ bar*m/s ] | Explosion Type | |
| St0 | 0 | No | |
| St1 | 0< | 200< | Slim |
| St2 | 200< | 300< | Strong |
| St3 | 300< | Very powerful | |
Classification of Explosive Zones
| Danger Zone | Gases, Vapors, Mists (G) | Powders (D) |
| The zone where the explosive gas mixture is constantly present | ZONE0 | ZONE 20 |
| Zone where explosive gas mixture is likely to occur | ZONE 1 | ZONE 21 |
| An area where there is normally no explosive gas mixture, but if there is, it will not remain for a long time | ZONE2 | ZONE 22 |
