Respiratory issues associated with limestone extraction and processing are among the oldest recognized workplace safety hazards. Modern limestone handlers often take a number of safety measures, including masks, respirators, enclosed processing systems, sprinklers, hoses and/or frequent cleaning schedules.

Beyond potentially increasing the cost of operation, cumbersome equipment and unpleasant cleaning procedures all add to processing costs and can take a toll on staff morale.
