| Abstract |
An industrial hygiene survey was conducted at the Agrico Chemical Company, Pierce, Florida, June 22-26, 1975 to collect environmental data on exposure of personnel to sulfuric acid, phosphoric acid, chromium, uranium, fluorides, and radiation during the cleaning of the phosphoric acid reactor vessels. The process of phosphate fertilizer manufacturing is described, and information is given on the medical, safety and industrial hygiene program at this facility. Concentrations of fluoride, phosphoric acid, cadmium dust, chromium, canadium dust, and sulfuric acid were all below the legal standards. Recommendations are made for improving the safety of the tank cleaning procedure. Agrico's facility is not suitable for epidemiological study because the latency period is too short and also the medical and personnel records were not adequate to perform a retrospective mortality study. Data on uranium and radiation exposure will be included in a separate report. |
