HOLEMAKING IDEAS FOR KEY Deita, , On June 7 1972 stringent Federal regulations went into effect on the commercial use of asbestos. We at Montello determined to ascertain how our unique, wet-refined Super Visbestos would perform, in the context of these O SHA regulations, under the w idely varying conditions found on drilling rigs. . MEN Four on-site tests and their evaluation have now been completed. Three different forms of our asbestos were checked to determine the effects of fine grinding, coarse grinding ( i . e . crushing) and granulating, on air-entrained dust concentrations. Below is a recap of the more important points from this study. Feel free to contact our Sand Springs office for a complimentary copy of the complete report. * 1. A ll tests were performed using M ontello's exclusive wet processed asbestos products. The findings cannot be safely applied to any of the several dry ground products on the market. 2 . Fiber counts were highest on fine ground material and lowest on granular m aterial, with coarsely ground (crushed) materia! falling between these two. 3 . Crushed Super Visbestos, which has been used ?n the field for sev eral years, consistently fell well below the O SH A regulations as to maximum ceilin g lim it and 8 hour, time weighted average, (TWA), 4 . New Granular Super Visbestos, now available in the field at no extra cost, proved to be from 20% to 50% cleaner than Crushed Super Visbestos. 5 . Neither form of Super Visbestos exceeded even the much mare stringent TWA level which w ill become effective in 1976. 6 . Based on this test series, Super Visbestos in either form offers a safety margin of 5 to 1 or more, in complying with the limits set by the regulations. Therefore, we believe there is no reasonable expectation of exceeding the legal lim its, when using Crushed or New Granular Super Visbestos. (See other side for corroborating data) P.O. BOX 130.

Drilled cuttings must be flushed from the hole!
