[Control of human errors and comparison of risk levels after correction action with the SHERPA method in a control room of petrochemical industry]

Human errors in many jobs especially in nuclear, military and chemical industries may bring disaster. Supporting this proposal there are many evidence around the world such Chernobyl disaster in 1986, Three Mile Island accident in 1979 and Flixborough explosion in 1974. Therefore, human errors' identification especially in important and complex systems is necessary and thus predicting control methods are unavoidable. Recent research is a case study performed in Zagros Methanol Company in Asalouye [Southern Pars]. The study tools were observation, interview with experts and control room operators, inspecting available technical documents, and completing systematic Human Error Reductive and Predictive Approach [SHERPA] worksheets. Analysis of SHERPA worksheet indicated that,%71.25 were unacceptable errors,%26.75 undesirable,%2acceptable [with modification],%0 acceptable. Predicted risk assessment after modification was%0, unacceptable errors%0, undesirable errors%4.35, acceptable [with modification in future]%58.55, and acceptable errors%37.1. The study showed that the current implemented method can be used through various industries like to chemical and petroleum. Based on the results of the risk level assessment after modifications, once the system weaknesses were refined or controlled we should expect a decrease in the amount of human errors causing disaster

Study of quality of work life [QWL]

A high quality of work life [QWL] is essential for organizations to continue to attract and retain employees. QWL is a com-prehensive program designated to improve employee satisfaction. This research aimed to provide insights into the positive and negative attitudes of Tehran University of Medical Sciences [TUMS] Hospitals' employees from their quality of life. A cross-sectional, descriptive and analytical study was conducted among 908 TUMS hospitals' employees by questionnaire at 15 studied hospitals. A stratified random sampling technique was used to select respondents as nursing, supportive and paramedical groups. The results showed that the majority of employees were dissatisfied with occupational health and safety, intermediate and senior managers, their income, balance between the time they spent working and with family and also indicated that their work was not interesting and satisfying. TUMS hospitals' employees responding to this survey have a poor quality of work life. We suggest more training and educations for TUMS hospitals' managers on QWL issues are planned
