Abstract: A system for use with a gunite rig to capture airborne gunite type materials, particularly those containing silica, during the preparation of the gunite. In one respect, as the bags of silica-containing material are placed in the mixing section of the gunite rig and ripped open, airborne gunite dust is captured by a hood and suction system positioned above the mixer. Further, the mitigation system includes a plenum box and suction system positioned adjacent the mouth of a gunite pot to capture gunite dust generated as the mixed gunite material falls from a hopper into the gunite pot.
