W. J. McConnell of Metropolitan Life to O. H. Cilley on Firms for Dust Removal (1936)

A copy of a letter of February 24, 1936, from Dr. W. J. McConnell, assistant medical director of the Metropolitan Life Insurance Company and director of its Industrial Health Section, to O. H. Cilley, assistant general manager of Raybestos-Manhattan's United States Asbestos Division at Manheim, Pennsylvania. Answering Cilley's request to Dr. Lanza for firms experienced in dust removal, McConnell named three represented on the American Standards Association's committee on the design of exhaust systems: the Blaw-Knox Company, B. F. Sturtevant Company and Carrier Engineering Corporation. But he suggested Cilley first visit the North Charleston plant, where "Mr. Jeffords has done an excellent job in controlling dust."

What it shows

After Metropolitan Life's 1935 survey found high dust counts at Manheim, the plant's managers looked for engineering help, and Metropolitan pointed them to their own company's North Charleston, South Carolina, plant as the model. Manheim had already asked North Charleston for its dust control designs in September 1935.
