Silica Exposure Safety: Mini-baghouse Systems and Methods for Controlling Particulate Release from Large Sand Transfer Equipment
CDC/NIOSH scientists have developed an effective point-source control for silica-containing dusts that can be generated from machinery on sites where hydraulic fracturing is occurring. The CDC/NIOSH mini-baghouse retrofit assembly is a bolt-on control designed to contain silica-containing respirable dusts generated during refill operations of sand...
