Risk assessment is of paramount important in industrial plants due to the nature of work. There are many risk assessment methods used in industrial plants. However, it does not suggest a specific approach on how to assess the risks. Therefore, the purpose of this cross-sectional study was to integrate the event tree analysis (ETA) and analytic hierarchy process for assessing the risk of formaldehyde exposure in the process of grinding wheel. A cross-sectional study was conducted in June - August, 2020. An analytic hierarchy process by Expert Choice V.11 was used a tool for determining relative weight of probability of measures to prevent exposure to formaldehyde concentration in the air. RAM Commander V.8.6 was then used to assess risk from event tree structure with consideration of the probability and impact of the risks. The findings revealed that improper working layout in combination with inappropriate wearing respiratory protective devices to reduce exposure to formaldehyde were a high level of risk and improper general exhaust ventilation, improper working layout in combination with inappropriate wearing respiratory protective devices to reduce exposure to formaldehyde were a moderate risk. The company board and management should include potential failures of measures to prevent exposure to formaldehyde and actions to be taken to prevent exposure to formaldehyde in order to efficiently address the risks that are likely to arise from routine operational procedures.
