  • The History of Quarrying Disease of the Lungs from Dust

    Further, when slate miners and quarriers were distinguished from slate masons (millmen), higher mortalities were found to be exhibited by the group which was more exposed to dust (i.e. the masons). Penrhyn slate, worked by these men, was found to contain from 25 to 42 per cent. of quartz; while dust arising therefrom contained from 50 to 80 per cent. of fine quartz.

  • What is the best way to cut slate tiles safely?

    Respirable crystalline silica (RCS) may be generated when these materials are fractured through cutting, mining, blasting, drilling and polishing. How is RCS released during slate and tile cutting? High levels of crystalline silica dust are released when cut-off saws are used to cut roof slate and tiles, and this applies regardless of the size of the material or the length of time that it is
