In response to a request from employees working at the tube mill in Building 41 of the T-L Irrigation Company (SIC-3523), Hastings, Nebraska, an investigation was made into metal fume fever from exposure to the galvanizing process, carbon-monoxide (630080) from a farm tractor used inside the building, and unsafe machinery. The tube mill formed hydraulic tubing from coiled galvanized steel. All seven employees of the tube mill were interviewed. Three of the workers had been employed in this building for 5 or more years. One recalled a past acute illness including headaches, nausea, chills and fever after exposure to fresh zinc-oxide (1314132) fume while working as a scarfer. He was transferred to another task and suffered no more symptoms. The other two reported no symptoms. Metal fume exposures were well below evaluation criteria. Excessive carbon-monoxide exposure was not detected. The authors conclude that the occurrence of metal fume fever or other symptoms related to metal fumes did not appear to be a problem. Exposure to carbon- monoxide did not appear to be a health hazard. The authors recommend that possible noise exposures be studied. A duct velocity of 1400 to 2000 feet per minute was recommended for controlling zinc- oxide fumes.
