NIOSH 1983 May:3 pages
Health hazard control measures, work processes, and existing control technologies were evaluated at Louisville Fire Brick Company (SIC- 3255), Grahn, Kentucky in September, 1982. The company employed 35 workers involved in the manufacture of fire bricks from locally mined flint and flint clays containing silica (14808607), alumina (1344281), iron-oxide (1309371), titania (13463677), lime (1305788), magnesia (1309484), and alkalies. Raw clays and salvaged brick waste were crushed to 12/20 mesh, then blended with 2 to 6 percent water. The blend was fed to a hydraulic press and standard refractory shapes were formed. Oversized and irregular shapes were formed by hand. The shapes were dried and fired for 5.5 days at 2400 degrees-F. A union management committee performed periodic inspections, and health and safety posters were displayed throughout the factory. Hard hats, safety shoes, and eye protectors were provided. No specific engineering controls were employed. The author does not recommend an in depth study of this company since no unique state of the act control technologies are employed.
