The aim of this study was to evaluate workloads as perceived by the operators of an oil distribution company in Southern Brazil. Workload levels were measured by a questionnaire adapted from the NASA-TLX, and the factors that impact on the workload were identified by interviews and questionnaire. The results showed that the workload level is high, mainly due to technical constraints (such as equipment and computational problems). Performance is the component which most influences workload. According to the results, it is necessary to improve the technical and organizational subsystems of the oil distribution company in order to improve human performance as well as the health and safety of the operators.
