Of the three men, was the foreman, would appear to have been in the tank the most (and the evidence is fairly clear on this presumption) was effected the least, ^ ^ ^ w h o would appear to have had intermediate time of exposure of the three men, was moderately ill. Anna continued to have symptoms for considerably longer than would have been expected. It is of interest that the urine lead levels on this man continued to be high for much longer than would be expected. The evidence is fairly clear that spent the least time within the tank and he is the one of the three who was most severely ill and succumbed. No respiratory protection was used excepting a canister mask used by but this was used only the afternoon of the third day. The concentration of lead in the urines o f V M ^ B t n d and in the tissues of !was sufficiently elevated to confirm the diagnosis of lead intoxication. This is clearly another instance of failure to use respiratory protection in a tank which was undoubtedly extremely dangerous. Although the writer is not impressed with the reliability of sludge analytical methods nor the necessary correlation between percentage lead in sludge and that in air it nonetheless should be mentioned that the organic lead concentration in sludge was quite high (before cleaning started sample showed 0.13% lead and the day after cleaning 0.23% lead). There is reason to believe that tanks which remain idle some time 10-27-1963 - LWS H E 0017582
