In-Depth Survey Report: Occupational Hazard Control Options for Chemical Process Unit Operations at U.S. Steel Corporation, USS Chemicals Division Site, Haverhill, Ohio

摘要

A survey of control technology of chemical process unit operations at US Steel Corporation (SIC-2865), Haverhill, Ohio was conducted in June, 1984. The installation manufactured a variety of chemicals using widely dispersed open air, chemical processing facilities. The main elements of engineering control were isolation and automation of all processes. Venturi blowers on loading platforms were used to augment existing wind currents during bulk loading of product tank cars and tank trucks. Where possible, material substitution was employed, For example, aniline (62533) was produced by the high pressure reaction of phenol (108952) with ammonia (7664417) rather than the usual benzene (71432) reaction with nitric-acid (7697372), followed by hydrogenation to aniline.
