Abstract Overexposure to airborne respirable silica dust can cause debilitating or fatal respiratory disease. Drillers and operators of mobile excavating equipment such as bulldozers, loaders and trucks at surface mines are frequently overexposed to silica dust. Enclosed cabs with heating, ventilation and air conditioning (HVAC) systems are typically integrated into the mining equipment to protect the operator from the outside environment. The National Institute for Occupational Safety and Health (NIOSH) investigated various cab air filtration systems in the laboratory to evaluate their dust protection performance. Findings are summarized in this leaflet. It was found that air filtration performance depends on the efficiency of the air filters, airflow through the filters, dust loading on the filters, exterior air leakage around the intake filter and wind penetration of outside air into the cab enclosure.
