E. JOHNSON Plant Manaftcr October 2, 1945 Mr. Frederick Laist, Vice President International Smelting and Refining Company Room 1720 - 25 Broadway New York 4, New York Dear Mr. Laist: A recent survey by members of the staff at East Chicago, also by representatives of the State Board of Health, convinces me that we should improve the ventilation to eliminate the dust hazard in the area at the Zinc Oxide Plant where leaded zinc oxide mixing and bagging is carried out. The survey showed that the dust hazard was from ten to twenty times the allowable figure, and both groups recommended that we correct this condition. The enclosed letters by Mr. Bowman, Mr. Knox and Mr. Toney are, I believe, self-explanatory, and outline the need for the proposed equipment. For your consideration, I am enclosing Appropriation Request No. 168 which covers an addition to Oxide Department Drscco Dust Collector in. the amount of $1,800.00, which should properly ventilate this area.
