Solid particles generated by mechanical processes such as crushing, sawing, or sanding.

Explanation:
Solid particles produced by mechanical actions are dusts. When you crush, saw, or sand materials, tiny dry solid fragments become airborne. Those particles can vary in composition and size, including respirable fractions that can reach deep into the lungs, which is why dust exposure is a common industrial concern and is addressed with ventilation, dust suppression, and appropriate PPE. Fumes form when vapors condense after volatilization at high temperatures, smoke comes from combustion and contains soot and other combustion particles, and mists are droplets of liquids dispersed in air. The description here clearly matches dusts as the solid particles created by mechanical processing.
