The next area OSHA plans to check is an open hearth roof. When an open hearth furnace has completed its campaign, the remaining brickwork is knocked in. When the roof is dropped, a large amount of dust is created. OSHA plans to measure this dust for asbestos fiber content since all Homestead roofs contain asbestos. Preliminary discussions with GRC and C.D. Jamison indicates that OSHA will probably find asbestos fibers. Whether the amount they find is within limits, we won't know until the measurements are taken. However, if the amounts found are above acceptable limits, U.S. Steel will be ordered to discontinue this practice. This will mean all U.S. Steel shops."
