    limestone produces dust which is re-leased into the atmosphere during blast-ing. Quantities of such dust, which is released intermittently, have not been reported. There is little that can be done to confine this dust as long as blasting is the means of shattering the rock loose. Often the noise produced 32 is as objectionable as the dust. For-

    Dust Monitoring OHSA Occupational Health Services

    Dust monitoring programs should ensure a reasonable representation of the dust exposure for given activities and the work site. Programs should be reviewed every two years and appropriate changes made if programs are inadequate for intended purposes. Dust Sampling. Airborne dust samples may be either static or personal.
