A New Risk Assessment Criteria in the Process of Fuel Oil Unloading

Abstract

Nowadays fuel oil transportation in Thailand is mainly transported by truck to the gas station, which is a service that affects the environment and the safety of the community. Although, the gas stations are strictly regulated by law. There are also small gas stations that do not have enough operational control measures to cause unexpected and life-threatening events. Therefore, the purpose of this cross-sectional study was to establish the new opportunity criteria and calculation the relative weight of likelihood criteria by using Delphi technique and Analytic Hierarchy Process(AHP) in order to receive the criteria of opportunity with precision and reliability in the process of fuel oil unloading. The findings revealed five criteria consisted of safety devices, work instruction, worker, Equipment of fuel truck, and work environment which values the relative weight according to AHP’s approach were 0.420, 0.281, 0.153, 0.098, and 0.048 respectively. A new risk assessment formulation was constructed to assess the fuel oil transport process in Phichit province. The scores of opportunity and severity criteria were moderate and high level respectively. Therefore, the risk assessment result was high level. Safety measures must be taken to reduce the risk for the process of fuel oil unloading. Limitations and future work of this study were also discussed.
