ABSTRACT
Introduction: The effects of accidents vary from minor injuries to fatalities and from insignificant damage to very severe damage to the environment and property
In order to prevent accidents in the work place, the root causes of and events should be identified using a systematic method and the results should be published. The current study aims to investigate the given causes of an accident in order to implement preventive actions in accidents and similar organizations
Methods: In this case study, after choosing the main event; to analyze the accidents, at first a set of questions in MORT were answered. By answering the questions, the final events, and the inappropriate management risks [color-coded red] followed by the leading causes of the accident were identified
Results: After analyzing the given accident, 22 inappropriate final events [color-coded red] and 4 assumed risks were identified. Of the total 12 identified basic causes, about 75% were classified as the management policies and decision makings group, 17% as the individual factors, and 18 % as the environmental factors group
Conclusion: The analysis using MORT method helped the organization with learning lessons from the accident especially at the management level. In order to prevent the similar and dissimilar accidents, the inappropriate informational network within the organization, inappropriate operational readiness, lack of proper implementation of work permit, the inappropriate and lack of updated technical information systems regarding equipments and working process, and the inappropriate barriers should be considered in a special way
ABSTRACT
Introduction: Primary schools are children's first social environments. Other people's attitudes towards environmental hazards play a key role in developing children's personality. This study aimed to identify and assess the environmental risks [such as emission of pollutants into the air, discharge of pollutants into water and soil, energy consumption, etc.] in Shohadaye Kork girl primary school in Kashan, Iran, and investigating the role of environmental education in the promotion of students' environmental knowledge
Methods: In this quasi-experimental study, at first environmental hazards were identified by a checklist through field visits and observing students' activities, and then they were assessed through Preliminary Hazard Analysis [PHA] method. After that, the Risk Assessment Code 1 [RAC1] was calculated. By Considering the hazards involved, environmental education was presented and then RAC2 was calculated. Environmental awareness of 172 students was investigated by a questionnaire. SPSS v.19 was used for statistical analysis
Results: 26 environmental hazards were identified, including 22 acceptable and 4 unacceptable [critical] hazards; 21 could be directly resolved by proper education
The mean scores of students' environmental tests were respectively 5 and 18.21 before and after the education
After taking control of measures all hazards were placed within the acceptable range
Conclusions: Schools environmental management plays so important role in preparing students for environmental education that the results of this study showed a significant relationship between education and promotion of students' environmental awareness
