(DDT MATCH COMPANY, LIMITED To - Ironchi All Branch Managers Vancouver to Fort Villiaa AH'a. ofi e.G. Ladd, A.L. Seines, L.T. Reid___________ __ Gentleaen: Attached la a copy of a clipping taken front the November 7th, 19&8 Wall Street Journal about the harmful effects of asbestos. One American architect, vho has a large steel frame building under construction has already reacted to this article and has vamed the owner that additional pre caution should be taken to protect the occupants from dusting and fallout after completion. 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 recommends covering the whole applicatlo with a glaze coat. J* Also attached is a copy of the Boyle Engineering Report on the "Effect of High Velocity Air Upon the Surface of Mono-Kote Material". The combination of these two items should persuade architects that Mono-Kote is a much 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 see it is dangerous. Ve aren't entirely "out of the woods" on this one ourselves. Ve require all empl mixing and bagging our mixed products to wear respirators and therefore they have no danger from asbestos exposure. If any plants need replacement warning signs, let me know. It is vital that our rule be enforced. The potential problem with Mono-Kote is-*t the plaster mixer*. There is sufficien asbestos in Mono-Kote to be harmful to mixersen. Once it is wetted there is no problem, so people at the nozzles are safe. Whenever you have a sizeable Mono-Ko Job you should insist that the people at the mixing station wear respirators. 3M ' have a lightweight disposable mask that is readily available.
