Excerpt from Industrial Poisoning in Making Coal-Tar Dyes and Dye Intermediates In the manufacture of dyes the only cases of benzene poisoning so far reported have been of the acute type, resulting from a single exposure to more or less beav fumes. One instance will be sufficient to illustrate this sort of acci ent, for all the reports read very much alike. A man was sent to the top of the benzene washer to change the piping on the spray nozzle. He was told not to go into the washer, which was empty but had not been cleaned. He ignored this order, took off the manhole cover, placed a ladder down into the washer and went in, one of his helpers following him. The moment he got to the bottom of the ladder he felt that he was going to faint. Started to climb up but would have fallen if two helpers above had not caught him and dragged him out. As they did so they saw the other man fall on the bottom of the washer, but they were obliged to help the pipe fitter down from the washer before they could return for the helper, and by the time they got him out he was dying. In this case no attempt had been made to render the washer safe because the man was not supposed to go in, but there are repeated instances recorded of severe and even fatal poisoning in men who have not been allowed to enter the tank or still until it has been emptied and steamed out repeatedly. Even a helmet of the Draeger type is not always sufficient for protection. Not long ago a man who wore one of these helmets fainted inside the tank and died soon after he was removed. The only explanation that could be offered was that the helmet had not entirely prevented him from breathing through his nose. Several cases on record in Germany show how dangerous mav be the work of cleaning and repairing receptacles that have held ben zene. Lewin5 in 1907 reported a case of fatal poisoning in a work man who had tried to rescue a man overcome with benzene fumes. A benzene kettle had stood empty for 22 hours, then it was washed out three times with cold water and twice with steam and was allowed to stand all night filled with cold water. The man who was sent in to make repairs took with him a pipe through which was blow ing a stron current of compressed air. Nevertheless, he fainted and fell to the iottom of the kettle. Several men tried to get him out. But all grew dizzy and confused and had to give up, when an engi neer, with a diver's helmet succeeded in dragging him out. He was revived, but one of the men who had tried to rescue him died 10 minutes after climbing out of the kettle.
