The authors evaluated occupational accidents in Kocaeli, Turkey, using epidemiologic criteria. Data were derived from the registries of the service on Occupational Injuries and Diseases of the Social Insurance Institution's District Authority in Kocaeli. The analysis was based on data from 387 deaths. The rates of occupational injuries and mortality and fatalities from them were 5.1%, 30.6 per 100,000 workers, and 6.0%, respectively, compared with 2.8%, 35.2 per 100.000 workers, and 12.7% in Turkey. Sectors with the highest rates of fatal occupational injuries were construction (30.2%), transportation (13.2%), basic metal industry (9.0%), manufacturing of metal products (5.9%), and heating with electricity, gas, and steam (5.9%). 38.2% of these workers were 25-34 years old. Nearly all were male, most were married, and three fourths had children. Of all deaths due to occupational injuries, 121 (31.3%) were caused by traffic injuries, 93 (24.1%) by falling from high places, and 43 (11.1%) by electrocution; 89% occurred at workplaces, 42% of the workplaces were small, and 45.9% of the deceased workers had been working there for less than three months. Although the situation was better than that in the rest of Turkey in terms of epidemiologic criteria, the death rates, as in other developing countries, are higher than those in the world in general.
