Tha fact that only "Ion* fibor" chrysolite asbestos ia uaad at tha 8tratford plant la fortunate, no doubt. Tha duat found In saaplos No. 1 and Ho. 2 was ao Uttla aa to seem non-hatardous ao far aa aabaatoala (aa distinguished froa oanoar produotlon) la oonoarnad. Ohdar tha talcroecope, no fibers war# aaan that had tha oharaotarlatlo appearance of aabeetoa fibers and thla au**aatai (l) tha duat aa all either ocasnt or lineston (both ara added along with asbestos to aake the slurry) or (2) the asbaatoa fibers aero present but ao slender, say O.Ol to 0.1 in disaster, that even fibers 10 to 20 In length could not be eean using the standard Methods of looking at duat with a aloroaeope. The point of this pert of tho discus sion is intendad to suggest that additional staples aust bo eollootod to confuse, if possible, the possibility that few or no significant nuaber of tabestoe fibers gat Into the work trot. Other procedures aay be used, perhaps, to greater advantage for thla purpost. Saaple No. 2 was unuaual because the operator, while per* fomlng the routine operation of filling a conveyance by shov eling into it a proper aaount of ground scrap shingles, caused a high section of tho scrap to caaoado to tho floor generating a brief but heavy cloud of duet. This probably aooounte for the greater aaount of duat found In this staple, since no clailar episode aeooapenied the earlier work oyele during which Saaple No. 1 was collected Ohless there was a significant but unde tested nuaber of aabeetoa fibers in these eeaplee, there need be no great concern about dustiness nesr the slurry tank. RKOMtanmoMi Additicagg eeaplee need to be collected to adequately appraise thejgmsatial dustiness of tho aanufaeturlng prooeases at the Strati*** plant. Noise level aseaursasnte should bo aedo during ecao future visit to tho plant. ward J, Largsnt RMC45000200001942
