Fig. 6: Airborne fiber concentrations recorded at Gary Works from 1994 to 2006.
From: Occupational exposure to asbestos in the steel industry (1972–2006)

Scatterplot of individual data points (representative workday samples are blue circles; task samples are gray triangles) from 1994 to 2006 across each department for which asbestos air samples were recorded at the Gary Works facility. This was the only facility in which data were available during this time period. One (in the Boiler House) of the 63 total samples during this time period exceeded the contemporaneous PEL (red dotted line) of 0.1 f/cc.
