Younc Purchas ing Agent Bethlehem Steel Corporation Bethlehem, Pa. 16016 Subject: Health Hazards from Profax Premix" Gentlemen: Thank you for your letter relative to the possible problems associated with Asbestos in the Premix. Asbestos levels are at 3.5% in the. mixture as currently supplied. We believe that this will be acceptable to the O.H.S.A. providing that the pulper man wears the correct form..of dust mask while charging. No problems are likely to exist once the product has been wet with water as there will be no dust during the forming operation. 3 The finished (dried pieces) do not, we believe, constitute a hazard as once the top has been heated, to about 2000P, by the steel the fibrous nature orthe Asbestos is destroyed and no special health problem is likely to exist. . ' Even though, as stated, we do not expect the Asbestos contained in Premix to cause difficulties in your plant, we obviously are continuing our efforts to improve all our products and are actively seeking alternative materials to Asbestos. At this point, we have not located any materials which will provide the combination heat resistance, insulation low cost and forming characteris:ics that i possible from the existing formulation. However, indications arc that at a increase in raw material cost, a satisfactory product containing less than 1-1/2% Asbestos may be possible in both Premix and prefabricated Profax products. if you are interested, we will be glad to arrange production tests.
