OFFICE MEMO TO: C. L. Crane H. C. Dodd FROM: L. A. Ashley SUBJECT: Asbestos - Cadwelding DATE: June 17, 1977 I talked with Jaaes Barry, Chief Engineer of Erico, concerning his testing of refrasll rope for eadvelds. One of your projects furnished his a 10 ft. sample. He told ae that they had satisfactory results with the refrasil but were concerned with the release of flourocarbons since the material was Teflon coated. Be is going to send ae a letter to this effect, In addition, beginning August 1, 1977 Erico will no longer furnish asbestos rope but a ceramic type rope, 1 requested that they send each of you 20 ft. prior to August in order that you might run some tests yourselves. 1 think ve previously tried this material unsatsifactorily but I'm not sure. In the meantime we will continue to use the asbestos rope. As soon as you can Inform ae of the results of your testing of the ceramic rope; at the same time I will ask our Industrial hygenlst to look into the potential flourocsrbon problem. ?cc: t. D. Pyeatt Bert Hale Carl Richardson L. A, Ashley
