To evaluate the mortality experience of the Steel Producing Department, they reviewed a previously conducted mortality study of the steel industry and extracted the data for the plant in question. Based on the results of that study, masons are likely to be at increased risk of work-related, non-malignant respiratory disease. Recommendations concerning environmental and medical surveillance are presented in the body of the full report. 收起
