ETHYL CORPORATION lOO PARK AVENUE BUILDING AT 41s t STREET NEW YORK 17, N. Y. April 26, 1957 Dr. Robert A. Kehoe Kettering Laboratory College of Medicine University of Cincinnati Cincinnati 19, Ohio Dear Bob Subject: Lead Warning Signs This will confirm our conversation in your office recently regarding the use of decals for lead warning signs in lieu of enamel metal. A survey was made throughout the country in 1950 on lead warning decals as compared to plastic signs. After twelve months it was found that the decals were unchanged while the plastic signs discolored considerably. Recently we have learned that the decals have been used by Shell in Canada with considerable success. In addition, our Canadian people advise that Shell in the United States is also using this decal. In view of the fact that the decal cost is approxi mately three cents as against twenty cents for the enamel sign, a considerable savings can be effected by the customer. As a matter of background, we are sending you some informa tion on the survey made in 195O. Your opinion on this would be appreciated. HKBrems Attach.
