You probably have an exhaust ventilation system to clean the air at your plant's bagging operation, but do you know that the bagging operators can still be exposed to unacceptable dust levels? This article addresses some of the less-recognized, secondary dust sources that can cause a bagging operator's exposure to except acceptable limits. Sections describe a US Bureau of Mines study and the secondary dust sources. Although the study described here was conducted in mineral processing plants, the information can be applied to bagging operations in plants handling other dry bulk materials.
