*\>NOLITE TO:- See Distribution List FROM: Thomas F. Egan DATE: April 17, 1970 Gentlemen: The attached article is very topical to say the least. This is sent to you for two-fold purposes: First of all, it is important that you be alert to the many changes taking place constantly in the field of direct-to-steel fireproofing. Secondlysince this effects our competitors (sprayed fibers) directly, it is important that you use these facts with architects who have used or are contemplating specifications for sprayed fiber fireproofing. For the present, please sell the inherent advantages of a cemen titious product. This article, having been written by Mr. Rosen, would be an ideal piece to distribute or at least use as a point of reference with all architects and engineering firms. Keep in touch on particulars. Yours truly, TFE/jac Attachment Thomas F. Egan SPECIFICATIONS CLINIC I at -AHOLD J. ftOUN Controlling Construction Pollution c?-; This column concludes llut due to its contribution to air pollution, asbestos-sprayed insulation must be eliminated in future construction.
