Title Case study - Comparison of occupational exposures among painters using three alternative blasting abrasives
Bibliographic information Sep. 2006, Vol.3, No.9, p.D80-D84. 11 ref.
Abstract This article presents the results of a comparison between specular hematite and other commonly-used blasting abrasives used by painters, namely coal slag and steel grit. Worker exposure monitoring was carried out over three consecutive summers on footbridge repainting projects in New Jersey. Personal breathing air samples were taken during blasting operations and analysed. All methods performed well in the removal of paint. All three abrasives created elevated exposures to lead, respirable silica and cadmium. Of particular concern is the presence of beryllium associated with the use of coal slag. Other findings are discussed. Specular hematite was found to be associated with lower concentrations of silica and heavy metals when compared to sand and metal abrasives, respectively. However, engineering controls such as local exhaust ventilation and hygiene measures such as showers are recommended in all cases.
