Rogers, Secretary Gypsum Association Safety Committee 201 North Wells Street Chicago, Illinois 60606 Dear Fred: .w .rr ** We believe the attached is of great importance to the Association , and member companies. You are aware that joint systems contain approximately 5Z asbestos, some mica and the balance is limestone. X. Based on threshhold limits adapted by A.C.G.H., mica (when exceed ing 57* free silica) can be classed as a respiratory irritant. Asbestos is very harmful, however we question whether the percentage used in a formula and after it is mixed in a batch could be considered harmful. We realize that someone will be the whipping boy, also product liability will be stressed. It is our opinion that the entire blame can be placed on the contractor, for not insisting on respirators and dust masks when sanding. We understaqg, that dust samples will be obtained during a sanding operation and .analysis made of the samples. We question this approach, the problem would be the large amount of dust, 10 microns or smaller that is generated by the sanding operation and breathed by the individual. We .will keep you posted of any other problems that may develope. In all probability, U. S. Gypsum and National Gypsum have been alerted end we will bs interested In-their-aesrsneh to minimizing the problem. __ Please send 500 "Watchful Wally" stickers and bill this-office.
