What are the explosion risks in industrial dryers and how are they mitigated?

Explosion risks arise when flammable vapors or dust reach explosive concentrations in the presence of ignition sources. Conditions: solvent evaporation exceeding LEL, dust accumulation within explosible range. Mitigation strategies: inert gas blanketing (N2, CO2) to keep O2 below limiting concentration (LOC), maintaining solvent below LEL with adequate airflow, explosion venting (rupture panels), suppression systems, grounding/bonding to prevent static ignition, temperature monitoring to prevent hot spots, and avoiding mechanical friction sources.
