ABSTRACT
In the insured of the agricultural cooperative life insurance program (12, 156, 022 cases), 12, 588 persons were involved in accidents in 1973 fiscal year. The following analysis was conducted on these 12, 588 persons with special reference to the 2, 218 persons who were involved in farm machine accidents.<BR>1. There were 3, 945 cases of traffic accidents. Of them, there were 2, 499 deaths and the fatality ratio stood at as high as 63.3%. There were 57 cases of traffic accidents involving farm machines. Of them, there were 42 deaths and the fatality rate was evidently high with 73.6%<BR>2. There were 54 deaths caused by farm machines excluding those caused by traffic accidents. Of them, 45 were caused by cultivators. The ratio was extremely high with 83.3%.<BR>3. Of the 45 deaths caused by cultivators, 26 were the cases in which the operators were pressed by fallen cultivators. In 13 cases, the operators were caught in between the machine and tree or building.<BR>4. There were the other 2, 164 cases of farm machine accidents in which the patients were later seized with sequelae. Of these cases, 564 cases (26.0%) were caused by cultivators, 379 cases (17.5%) by thrashing machines and 316 cases (14.6%) by reapers. The accidents caused by these three types of machines accounted for 1, 259 cases (58.1%).<BR>5. In the overwhelmingly large portion of the cases of accidents, sequelae broke out in fingers. Thus, 89.6% of those who were involved in machine accidents suffered from sequelae in fingers.<BR>6. There were 1, 939 cases of finger accidents, of which 1, 032 accidents were caused by machine belts and 441 by machine blades. The accidents caused by these two items accounted for 75.9%.<BR>7. From the statistical analysis, it might be said that the correlation coefficients between the number of farm machines available in a given area and that of accidents are less significant for cultivators and reapers, and that the environmental and working conditions are just as important elements as the number of machines.
