Air, Surface, and Passive Measurements in a Building During Spray-Buffing of Vinyl-Asbestos Floor Tile

A meta-analysis of airborne asbestos fiber concentrations from work with or around asbestos-containing floor tile

“…The fiber type generally used in VAT was chrysotile such that the fibers were distributed throughout the thickness of the tile [2,7,8]. There is no evidence to suggest that amphiboles ever constituted an ingredient of any VAT formulation, and this is consistent with the fact that many bulk-sampling analyses of VAT products have reported measurable levels of chrysotile but not amphibole [9][10][11][12][13][14][15][16][17]. Some studies have reported the presence of trace levels of amphibole.…”

“…Hundreds of short-term (considered in this study to be generally less than 60 min) and time-weightedaverage (8 h TWA) personal and area airborne asbestos concentrations measured during handling and use of asbestos-containing floor tiles at commercial and industrial sites [2,12,20,30,[33][34][35], in schools [1,8,9,11,[13][14][15][16]19,[36][37][38][39][40][41][42][43][44], in residential settings [34,35,45], and in a simulated exposure environment [10,18,[46][47][48] have been reported in over 30 published and unpublished studies. In general, most of the studies reported measurable asbestos levels with a large degree of heterogeneity.…”
