Dust Hazards

Most solid materials that can be ignited can form an explosive dust cloud if the particle size of the solid is small enough. Special attention should be pay to identification of accumulation of dust and powders in plants and to specified safe operating procedures for handling powders and dusts.

Practical Issues with Marginally Explosible Dusts - Evaluating the Real Hazard
