Noise and silica exposures are presented by quarry type in Table 2. For basalt excavation and portable crusher plants, mean noise exposures exceeded the hearing protection program level, indicating a need for a plant-wide hearing protection program. For sand and gravel operations, full shift exposures measured with the PEL and hearing protection

Silica Sand is quartz that over time, through the work of water and wind, has been broken down into tiny granules. Silica sand deposits are most commonly surface-mined in open pit operations, but dredging and underground mining are also employed. Extracted ore undergoes considerable processing to increase the silica content by reducing impurities.
