I* 2* ' 4y 23, 1966 Kennetn E. Keuper C. A. Park3 of Construction will investigate possible candidates for asbestos cloth substitutes. When a satis factory material is approved, we suggest it be considered as a substitute for asbestos cloth. Regarding the application of Limpet, it should not be sprayed indoors and only in roped off areas v/ith all personnel in area to wear cartridge respirator in addition to all other safety equipment. Finish to be applied before pipe or equipment sprayed Limpet is placed. The respiratory disease problem is an occupational hazard and if safety precautions are used both in our shops and in field application, we can reduce the hazards to the minimum. DESIGN DIVISION CUy?
