Barth Qjarlcatoa, *** Jq3 The dust survey lnduded la this report is supplementary to the survey aade la January, 1930 and was eoadactad to determine the extant of c. dost moral accomplished by tba installation of now exhaust equipment and redesign of old emhauet aquLpaant. Tba nabtr of buildings, tba processes and arrangement of machinery are tba sane as at tba. tine of tba previous survey* tbs exhaust systems of tba cards have bean redesigned to cover tbs c naehlnas aora coapletaly. In an a^pexlaentd ease one card was covered as eoaplately as possible* This aschina was enclosed la aaslln and an alx sample vae taken tba aaclosure and tso general air sa^las vara taken in the card roan proper at tba saaa tiaa. Tba first set of saaples was taken before tba conveyors from tba preparation rooa began to bring tba fibre to the bins in tba card non* A second sat of air samples was taken after tba conveyors had bean carrying fibre to tba bins for aora than an hour. in axbanst systan and revolving brush are In use for the inspection c of vovan doth in tba weave rooa* Biis work waa formerly dona by band brush ing. U* looaa fibn Is brusbad froa tba doth In ordar that any flaws could ba noticed and Jta ir saiipls tu taken At the table and two general air saaples were taken is the weave rooa at the same tine -- one eet was taken with both the revolving broeb and axhsnst fan running and one eet with the revolving brush operating but without the exhaust fan* One set was taken with the workaan bruahlng the doth by hand, the aathod used before the exhaust aystee and -revolving brush were Installed. The Inspection table was enclosed with beaver board and a aeries of samples was taken both inside the enclosure and outside. The following tables Indicate the analysis of air saaples taken at representative points in the different depextaenta. Attention la called to the feet that the previous survey was aade In January and this survey In July. I Tartlols sine eedeureeente were nada of the dust by a direct projeoasthod. The results ere tabulated and appear in the graphs attached at the rear of the report. It will be aoted that froa 92 to 98.5? of the partlelee ere lees then 10 microns In greatset disaster. A discussion of the disease asbestosis and e correlation of the X-ray flattngs are reserved for the general report. MMIumi BM aapla a*.
