Jackson 1, The research proposal ceceived from Saranac Laboratory pertaining to tha relationship of pulmonary car-ccr to as'oestasis was reviewed in detail. Share is increasing publicity bate in the professional arc. popular literature concerning the relationship of ascestasis to cancer. Several articles tying the tws isgsihar wer; cited by the ccrssittae. For exac-ple, in the Consumers1 F.eports, a popular publication of national distribution, one of the ceraer car.paai.as reported that the;* current!;-' have a workmen's ecaaer.. saiion caso clairing that pulmonary cancer was caused by ' exposure to asbastesis. It is obvious free the Saranac proposal that research into this field is exceedingly ccaplex; that tho techniques ar? difficult; and that a considerable length of tine and a largo ir-nasr of croerineatal aninsls are required, ^he Saranac proposal covered a three year period. It vtas tha consensus of the ccnrittet' that an additisnal proposal be obtained frees another research agency and ' reviewed before caking a definite rsconmer.daticn to the Doard of Governors, It was also suggested that whan our thinking became crystallised, other asbestos industries, such as the -asbestos ceneat, tha insulation and asphalt ' tila -groupi, to appreashad to ccopara'ce in the financing 9 of the re, search 2. It was recalled that in Dr, Scherers1 visit to the ccmittse, mention had been nan* of tha carcir.cgeric properties of cercain oils and lubricating products that sight ba involved in the fibre conditioners. P-ecorrsendation was undo that further information concerning this potential haaard be obtained and forwarded to. each ccersittee ostbsr.

Tha Comal*tea reviewed the practices and methods of maint-2r.ar.ee and' opera tion of dust control systems. Since tha standard dust survey methods arc Inng'chy and costly proccd".rcs, it '..`as the consensus that assurance of th* uffectivo operation of a ventilation control system could be obtained. i through frequent and regular checks of air flew and pressures.
