I m sorry t.o '..rouble you age in but three points c*rnt up at ft recent Technical Committee meeting on which I have beer, asked to obtain vour comments. (1; Sylphon Seel - Is it still being uanl at E*ton Houg-e end is it cons tiered satisfactory? I did make an enquiry on this in my letter of tine lof'n i'ftl r'Prv, 1948, (2) The form, type and construction of the activated carbon air filter place! on the air inlet of the compressor. (3) A section of the Wnngeraent here is pressing for the removal of still looths. Another section, including myself, want to retain' them, as there have been- a number of leaks recently and one spill, and the booths at ', least keep these isolated. I understood from you that in one building at'' baton Houge the still booths h>-d been removed. This made cleaning and the operation much easier, , and, moreover, there has been no appreciable' -increase? in tbs load absorption and excretion of the men employed in'this particular building as compared with those buildings in which booths were still installed. Has t'\i: picture changed since Baton Rouge has been on the reduced .cycle sndt heavier charge? '"as anyndditionnl ventilation or redesign required for the* still floor without booths? . ,\ *"' ' l'rofeasor Pavlovsky of Buenos Aires is in this country t the moment and irofessor Dodds is throwing a luncheon party for him tomorrow at the Dorchester, n t .which I shall be present. I am bringing him bcfc>.here tomorrow evening, and showing' him eround the plant on Friday. From .present knowledge he looks after twelve plants in the Buenos Aires area. He has' been asked by Risso-uill to advise on the ap^ ointments of 'consultants at s.ix' projected plant' ir; other parts of .Argentina , discussion. I will let you know the" outcome '-.of our nowhere. doing `.V. i y`ri reft'rird3 this | lent at present, I am sorry to say wo are getting v T'rve got. it sin erf icial-ly clean, < r,! have a gang going- abound detailed cleaning in addition to that already done by the process A. Lchoe, Cincinnati. 2nd une, 194C. Da t e .................. workers. As result of our combined American experiences, some seventy-five modifications end improvements proposed are in abeyance owing to shortage of materials and men, end I cannot see *ny hope of a significant improvement in the degree of exposure here until these ere completed. In some places there is ' no ho^e of improvement; for example, there is not sufficient power in the exhaust motor in the furnace building to permit the installation of a jacket around the dry sludge chute and torque motor. V-'e have had some pretty bad spills here recently, including an over flew of a blending tank, which contaminated about 100 square feet of the floor and upset a test I was running. "'e had one volunteer to do a week on packing drums, blending, stencilling and bung cleaning, who let us have all samples passed here and at home. He was supposed to be on 0 52 hour week, with one dv off in every seven, but, unfortunately, one week he was permitted to go up to 70 homos. It is known trial if workers in this particular building do 70 hours without a break, they almost invariably show very high figures, and re iUire to come out of the building. I tried to fix a 40 hour limit, with one day off in seven, but this had to be modified to 52 hours to suit working coalitions. The type of work had no bearing on the excretions, which, with the exception of two samples, were above normal but within safe limits, strangely enough the excess of spillage did not show up in the lead excretion of urine, and the excretion on the day off was not significantly lov/er. There was a tendency, however, for the excretion to be lower on the dry following the day off when the individual had returned to work. It is appreciated that some costamina tiori of these samples is inevitable. We arc proj using to run a further test on this man for three months in the Autumn. I will naturally let you have the results. Last month we did a series of tests on dust masks issued to workmen in 1 he furnace and alloy buildings. All had been in use for approximately the same length of time. The load content of the -e masks was in inverse proportion to the amount of lead found in the faeces. L'e have since learned that we may have been unkind to some of the individuals concerned, as the face-pieces did not fit, and we are now endeavouring to ensure that the^e will be more than one type of face-piece so that each individual can ber issued with reasonable protec lion. V.'ith kindest personal regards, Tours very sincerely, 1 I * Davison RE 0013 3 GO
