Title Exposure profiles and source identifications for workers exposed to crystalline silica during a municipal waste incinerator relining period
Bibliographic information June 2008, Vol.154, Nos.1-3, p.469-475. 21 ref.
Abstract In this study, respirable crystalline silica exposures to furnace relining workers were assessed by conducting personal respirable dust sampling. All samples were analyzed for their tridymite, cristobalite and quartz contents using X-ray diffraction. Results show that quartz was the only detectable crystalline silica content. The operations with the highest levels of respirable quartz exposure were different from those for which respirable dust exposure levels were the most important. Nearly all workers' respirable quartz exposures exceeded the TLV-TWA (0.025mg/m3) indicating appropriate control strategies should be taken immediately.
