Personal exposure of workers to respirable silica dust of high silica content was determined in 2 steel fabrication yards, by means of MSA Gravimetric Respirable Dust Samplers, in an attempt to establish the reasons for the increase in the incidence of silicosis among sandblasters and associated workers. Free silica concentrations were determined either by colorimetry or by X-ray diffraction. Although wearing respiratory protective hoods, most sandblasters were exposed to excessive levels of silica dust several times greater than the threshold limit value. Other workers in the yards who did not wear any protective devices were also exposed to excessive levels of silica dust.
