Ba fait that tha answer oontoinad la this report aa to tha uaa of red load painto on thipa was wars or laaa final, is a re*ult, It would sens thet aoat of tha yards hesitate to uaa rad load baoansa of its toxicity which aaaat aa increase in eqidfncct if it were to ba used as a protective ooatlng.

Ha works wary closely with dr. D. F. Orahan and Kr. K. V. Tanfttsn. All three are quite wall satisfied with the perferannee of fomula 116. Clair difficulties aaaa to 11a prinerlly with tha use cf rad lead by tha favy personnel, khr. Oaaaow did adait that tbs rad lead fonauls 116 was not as objectionable aa the straight lead as tbs saount of rad lead por gallon was greatly reduoed and this would reduce the health hazard. At tha present tlse it would seat that because of this raport referred to above dated March 21, 1956 frea the Bevy yards that, owing to the health hasard alms, a straight zinc chrowate fomulatlen Is preferred by tha TUnry pore'mol. It sccs th.it .tr. Oocecv 1, governed acre by tha wishes of tho various Havy afclRnrds than by the ptrforaaoce of Forsula 116 as eenpered to fib. After lasvlng Hr. Qetsow, 1 dropped in on Hr.

It seaos that ease of thaw have obtained concentrations of rad lead In tha air greater than tha allowable concentration, Upon questioning Ur, Qrahaa and Mr. VanEtten, Z found that they did not know oa what conditions these o<-aplalnta wara based. It doas saaw that with a sraaller ooooentretice of rad lead In the vinyl rad lead pricers that they would have to be In a vary confined, ncu-wntilated anvlronwent to have concentrations of lead above tha allowable aacunt. Tba next tlas these people are interviewed lVwsuld ba wall to get aore details. Having a foe adnutes before mj train left for Mow fork Z want bo tha Bureau of Standards and called on Hr, Howard. Ha stated that Specification TT-J<46(a) which had been reported as being soeawhat unsatisfactory by Australian users evidently had been orrreeted by tha work of tha eoenittee through tha National lead Ocrpory lnborntuAta. They tv.vo hod no further oasplalnts of paints.in of? of tbtoe ftmletlofti in tT-A-ft6(a). X asked if there wore any rthar problsws oonoarnlng rad lead or rad lead pigaenta that bad ocas to Ms attention. Ha said there were none in regard to red lead and the only ooaplalnt in regard to the lead pigaents was ths staining of tha lead paints whan applied over ooppar. Him not Mistaken, all tha paints which ha Mentioned contained aino oxide. I believe tha obvious answvr to this would bo tho raeeval of tho sine cxldo sad so increase in tha white lead oontent. * N2793.01 Red Lead Technical Cowdttee 211 Meeting MiflOtea DKP^nVEVT ur THE NAVI ficH&o tr sxzn 0 VASHSiOlua 2S, D.
