background: an important factor in the prevention of industrial accidents is the ability of employees to maintain awareness of the work situation, understand the information it holds, and predict how situations will develop. in the present study, we examined the role of fatalistic beliefs and safety climate in predicting occupational situation awareness (sa) among workers.   materials and metho...

Stability of reinforced slopes is almost always carried out using limit equilibrium methods and controlled by the shear strengths of the slope materials and the extension force of reinforcements. According to limit equilibrium methods, the stability of slopes is assessed by dividing the whole failure wedge into several vertical elements. In order to determine the safety factor of the reinforce...

With the rapid development of natural gas pipeline, the safety of natural gas pipeline is paid more and more attention to. This paper presents a new safety assessment model based on fault tree and fuzzy neural network. Firstly, in the light of fault tree theory, fault tree analytical figure is established for buried natural gas pipeline system and the index system is established about buried na...

In the current practice, to determine the safety factor of a slope with two-dimensional circular potential failure surface, one of the searching methods for the critical slip surface is Genetic Algorithm (GA), while the method to calculate the slope safety factor is Fellenius' slices method. However GA needs to be validated with more numeric tests, while Fellenius' slices method is just an appr...

This white paper lays out some foundational information about different approaches to safety: how various industries differ in their approaches to safety engineering, and a comparison of three general approaches to safety (system safety, industrial safety engineering, and reliability engineering). An attempt is made to lay out the properties of industries and systems that make one approach more...
