By its nature quarrying has the potential to create dust ... Drill rigs should be fitted with appropriate and well maintained dust extraction equipment ... Hand drilling dust can also be controlled using dust collection equipment. It is preferable to drill these holes wet ... Hand held powered saws ... should not be used to cut dry.
