Data were collected through statistical forms and Medical Commissions Comprehensive System, as well as the data recorded in the SSO systems. The collected data were analyzed using descriptive statistics, Excel software, and SPSS 22.

Findings indicated that an average of 115 people (0.59%) die each year from work-related accidents. Occupational accidents also lead to total disability of 176 people (0.91%) and partial disability of 292 people (1.5%) per year. About 5% of the victims (998 people) receive lump sum payments as compensation for permanent impairment and 92% (17665 people) fully recover from job injuries. Work-related accidents impose an average financial burden of about IIR 147 billion annually on SSO as short-term costs, about IIR 247 billion as inpatient and outpatient treatment costs, and about IIR 497 billion as long-term costs.
