Crook Persoonel Header Cfcens-Cornicg Fiberglees Corp. iCaylo Division Berlin, tie* Jersey Beer it, Crooks: Ob Uareh 24, 1960, personnel from this Program collected eteospberie dust sample* io your plant* The resulting dust counts are reported in table 2, Is general, these shorn a lev dust count, hemeter, several results also indicate that the dust eoaoeatretions may approach or soaaihet exceed the threshold Halt of five million* of part teles per cubic foot of air* This iioit is recogoixed for asbestos coatiiciog airborne dusts* The eirborne dust is a composite mixture of particles of asbestos, silica and liae, as sell as the calcium interaction product referred to by the trade aaae ef kaylo. Is order to reduce the inplant airborne ccnceatretioa of this dust* the follosing recoonendatlons re vade: 1* Scaerpl ventilation - Improve the general rest nation of the build lag to augment the local exhaust ventilation as already installed at many locations along the production machinery* 2. ExitUa* ,xhat jmllitlnx sistea - Serrie* tbe existlng system sith respect to enclosure devices, dust loading, and general repair in order to secure the full efficleaey ef the iaeerporated desiga features to collect the dust at local sources of emission* Note: In a prel ini nary tour of the plant it was noted that considerable dust escaped at a isi in the flatvarc finishing liae* This condition however vas corrected at the time ef the above study* 42 008 0384 V WV-1040 OMos-Coraiog Fiberglass Corp.

This refers to several lfiter&ittent opera tions such as loading or unloading, and charging the asteriels fro* cars, lifts, end into aixing hoppers. Thank you for your attention to this natter.
