Compliance %

MIE (Minimum Ignition Energy)

Minimum energy to ignite a dust cloud. If MIE < 25 mJ, static dissipative measures are required.

K_st Value

Dust deflagration index — measure of explosion severity. Higher K_st = more severe potential.

DHA (Dust Hazard Analysis)

Systematic review per NFPA 652 to identify combustible dust fire, flash fire, and explosion hazards.

Zone Classification (ATEX)

Zone 20: continuous dust atmosphere. Zone 21: likely. Zone 22: possible but unlikely.

Explosion Venting

Passive device relieving explosion pressure through a designed vent area to prevent structural damage.

Dust Explosion Pentagon

Five required elements: combustible dust + oxygen + ignition source + dispersion + confinement.
