One of the most important field of economy is manufacturing. The highest number of occupational accidents occurs in manufacturing. In Turkey, more than half of these accidents occur in this field (56% in 2012). This study aims to identify the contributory factors of such accidents and examine the relationship between Lost Work Days (LWD), Post-Accident State (PAS) and Type of Accidents (TA) using data mining, correspondence analysis and chi-square test. The analyses have shown the most frequently encountered TA is "pressing of the body or members between two objects" and its predictors are Sector, Size, and Age, Experience, Hours Day. This type of accident is most likely to occur in sector 25 (manufacture of fabricated metal product, except machinery and equipment), with a higher likelihood for the businesses with fewer than 500 employees and in the employees aged less than 40. As a result, the incapability of work is found to be as a period of 30-59 days. Consequently, it is recommended that higher premium ratios should be imposed to urge the businesses to take measures and supervision practices by the social security supervisors should be more frequent.
