Background: Chemical contaminants present in the work environments include gases, vapors, and solid and liquid suspended particles. The number of factories producing chemicals has increased significantly. Each year, new products are introduced into the market. Consequently, the number of employees at risk of exposure to these materials is increased. Hazardous chemicals are used in the petrochemical industry that is one of the major industries in the country's economic development. Therefore, the aim of this study was a semi-quantitative risk assessment of health exposure to hazardous chemical agents in a petrochemical plant.

Materials and Methods: This was a descriptive analytical study for assessing the sanitary risks of hazardous chemical factors in the work environment through a risk assessment method provided by the Occupational Health Department of Singapore. Thus, initially, occupational tasks and processes were determined. Subsequently, all hazardous chemical factors were detected, and then, the degree of risk, the degree of exposure, and risk rating were determined.

Results: In total, 24 tasks were examined and risk assessment was performed for 19 hazardous chemical substances in this study. Among these materials, benzene and xylene had the highest risks and were used in various occupations. In this study, mean and standard deviation of age and experience of participants were 30.28 ± 7.87 and 5.98 ± 5.66, respectively. Moreover, 25.3% of participants in this study were single and 74.7% were married.

Conclusions: It can be concluded that 81% of chemicals used in this industry are rated at moderate and high risk. In order to control the identified risks, this study recommended programs and control measures based on the hierarchy of elimination, substitution, engineering controls, administrative controls, and use of personal protective equipment.
