Kehoe Dear Dr. Kehoe: Our safety engineers have recently supervised the cleaning or repairing of tanks having floating roofs in which a question arises upon which I should like to have your opinion. These tanks are customarily cleaned with the roof in a down position, that is from 4 to 6' off the "bottom. Workers congrjyayy|upon the roof and open manheads for ventilation or remove the natenl|lpi&:idh plates and work of similar nature. I feel sure that when sudS^gggpRik is gassy, a fire and explosion hazard exists around such openings. But the particular question I should like to ask you is whether or not, if such a tank contains significant amounts of organic lead, workmen operat ing as they customarily do without masks of any kind would he exposed to a lead hazard? Very truly yours, n. n W:GCL 0022569
