Subject: Asbestos Substitute Insulation Materials
Per your request, ve have investigated a number of alternate insulation materials which could possibly be substituted for asbestos containing materials presently used throughout the Casting Division.
Asbestos is a proven occupational carcinogen. The toxic effects of asbestos have been evidenced even at extremely low concentrations. In view of this fact, OSHA h3s established a stringent permissible exposure standard for asbestos, and it is expected that this standard could be made considerably stricter within the next few years. Such a standard almost precludes the use of engineering controls for providing a 6afe working environment. Instead, it will require industry to substitute alternate materials for present asbestos usage.
At the present time, there does not appear to be any one material on the market which can readily be substituted for asbestos in all its applications. Because
of its unique physical properties (thermal insulation, fire protection, reinfor cing agent, etc.), asbe6t06 has been widely used for many years. With the increased restrictions on asbestos usage, we expect more manufacturers to produce substitute materials; but, currently there are few such materials available and we have limited experience or knowledge about their uses. Included is information on three manu facturer's products we evaluated as well as some of our preliminary recommendations.
The recent developments in the aBbest06 issue have been a source of grave concern to all processors and users of asbestos containing materials. This may lead to an overreaction to assume that it 16 necessary to Immediately eliminate the use of all asbestos materials. Some operations are isolated or enclosed and the use of asbestos presents little risk of hazard to employes. Plant Engineering Office and the Indus trial Hygiene and Toxicology Department can assist Casting Division m identifying those operations where the continued use of asbestos materials would not cause an
unnecessary health hazard.
Some asbestos containing materials should not be too difficult to replace with substitute insulation materials. Present uses such as asbestos cloth and blanket (used as spark and heat shields), millboard, tape, gloves and mitts are included in this category. In general, where the material does not come into direct contact with extreme temperatures or is not subjected to abuse, then these substitute in
sulation materials should perform satisfactorily.

We have evaluated three manufacturer's products: the Carborundum Company's Fiberfrax ceramic fiber; the W. S. Libbey Company's fabrics based on DuPont Nomex; and Haveg Industries Slltemp. Of the three, Fiberfrax appears to have the most promising application. The chemical composition is primarily AI2O3 and SIO2 with other minerals constituting a small proportion. The material is manufactured in a vide variety of forms such S6: fiber, paper, blankets and felts, boards, and textiles, among others. The manufacturer claims a continuous use limit of 2300*F and excellent stability resisting corrosion. Slltemp, a derivative of S102, Is manufactured primarily as a textile and probably has more limited applications such as welding curtains. Nomex Is an organic polymer and it also ha6 limited applications; however, it does have properties which should warrant evaluation of Its use as personal protective clothing for employes.
As previously mentioned, we have limited experience with asbestos substitute insulation materials and cannot make any specific recommendations at this time. Instead, we recommend that Casting Division conduct 6hop trlalB of the above mentioned three materials to determine the feasibility of substituting these materials for currently used asbestoB materials. Plant Engineering Office could assist Casting Division in conducting these evaluations. Industrial Hygiene should be consulted to ensure that these alternate materials, in themselves, do not present an unreasonable health risk to employes.

SILTEMP* Thermal Barrier Cloth Passes
Welding and Burning Test
isstr:
These photogrophs depict o test similar to one devised by the
U.S. Novy to simulate the performance of thermal barriers to
S determine suitability for use during welding and burning applications. Note thot the molten steel does not penetrate the SIITEMP cloth and that essentially no smoke is generated even under 5 these severe heat conditions. Further, the cut-off section of steel plote is caught by the SIITEMP doth, thus simulating the
. prevention of possible injury to personnel, or damage to valuable equipment--or ignition of flommables Examination of the SIITEMP
pv cloth (final photo) shows the cooled steel lightly adhered to the si cloth. SIITEMP 188CH meets the requirements of Mll-l-24244
