Crystalline silica is in engineered stone, quartz, granite, and other stone products. Cutting, grinding, chipping, sanding, drilling, and polishing these products can release hazardous levels of small silica particles into the air that workers breathe. Engineered stone has the most silica so it can produce higher levels of silica dust. The best way to address and deal with these minor dust sources is to install a total mill ventilation system (TMVS). A TMVS provides a general purging of the plant air to minimize dust throughout the entire mill building, thus lowering respirable dust levels for all workers within

Lead dust can become airborne due to improper air flow or exhaust ventilation, which results in puffing of lead oxide at the mill inlet. Exposure may occur from handling lead pigs while loading the mill pots or the ball mill. Lead oxide dust may spill or leak from trunnion seals, bearing seals, conveying systems, and transfer points. exposure to quartz containing dust from construction sites was observed, after correction for potentially confounding variables. Construction industry workers are known to experience high exposure to quartz containing dust,indicating the potential for silicosis development.12Conrmation of this is provided by registry based studies, which ...
