FILE NAME: WR Grace (WRG) DATE: November 14, 1968 DOC#: WRG345 DOCUMENT DESCRIPTION: 1968 Letter from HF Bushnell regarding harmful effects of asbestos. E.O. Ladd, A.L. Seines. L.T. Held Centimes: ' .. . ` . Attached ie a copy of a clipping taken from the Movenher 7th, 1968 Wall Street Journal about the harmful effects of asbestos. One American architect, vho has a large steel fraae building under construction, has already reacted to this article and has varaed the owner that additional pre caution should be taken to protect the oeeupants free dusting and fallout after ceopletlon. I have a copy of that letter if ve should need to produce it in a critical situation. I don't expect that should ever be necessary. The product being applied is Cafco and the architect reeamends covering the whole applicatio with a glase coat. .* 1 - * ** . Also attached is a copy of the Boyle Engineering Report on the "Effect of High Velocity Air Upon the Surface of Mono-Kota Material". . The eoBblnation of these two it-ens should persuade architects that Mono-Kote is a sueh safer product to use than sprayed fibre whenever fire protection is used,, It should also stop the use of sprayed asbestos fibre as an acoustical material,, You can aea it is dangerous. Ve aren't entirely "out of the woods" on this one ourselves. Ve require all caapl nixing and ^eggirg our nixed products to wear respirators and therefore they have no danger trm asbestos exposure. If any plants need replacement warning algna, let ne know. It it vital that our rule be enforced. * .* .-- The potential problem with Mono-Kote is-mt the plaster mixer'. There la sufrides asbestos in Mono-Xote to be hamful to nlxemen. Once it la vetted there la no problem, so people at the nozzles are safe. Whenever you have a sizeable Moao-Ko Job you should insist that the people at the nixing station ear respirators. 3M * have a lightweight disposable mask that la readily svallabla. , .
