Abstract One of the key concepts in matters of flight safety is that of special (abnormal) situations, with airworthiness regulation and certification of aviation equipment being based on this concept. At the same time, one is forced to admit that today there is no explicit interpretation of the standardized traits of special situations, nor are they not fully elucidated in the scientific literature. In this article we propose a pyramid-based approach to interpreting special (abnormal) in-flight situations, which allows for risk assessment not using risk matrices, but instead relying only on the probabilistic characteristics of the occurrence of events. Using the presence of a causal relationship between the layers of the pyramid, we propose an algorithm for the transition of varying degrees of danger of special situations. This algorithm can be used to develop an on-board device that informs the pilot about the dynamics of transitions from one situation to another, representing each emergency situation in a certain color.

Introduction: Emergency ward nurses are exposed to occupational hazards. Job Safety Analysis (JSA) is a way to identify and assess job-related risks and provide control strategies to reduce risks. The purpose of this study was to evaluate Job Safety Analysis and compare the efficacy of control (engineering and administrative) interventions in emergency nursing. Materials and Methods: This was an interventional study performed to assess the risk by Job Safety Analysis (JSA) in three groups of nurses working in emergrncy ward of Shahid Rahnemoon hospital in 2019. First, the initial risk assessment code (pre-intervention) estimated, then the engineering and administrative controls were implemented and the secondary risk assessment code (after intervention) was calculated after three months. Results: According to the results of the study، risk of musculoskeletal disorders with risk score of 20, was identified as the highest risk in all three emergency nursing groups, also mean risk assessment code for the occupational hazards in nurses was calculated which was in the unacceptable risk range and reached an acceptable level after performing administrative and engineering interventions. Conclusion: Results of this study showed that the implementation of engineering and administrative interventions had a positive effect on reducing the mean risk assessment code, also risk assessment code for occupational hazards reduced to almost the same amount with the implementation of each engineering and administrative intervention. This indicates similar role for these interventions in reducing the risk level.
