Background: The effectiveness and adequacy of occupational health and safety management system should be monitored and evaluated at organization level on a regular basis. Safety audit has a clear role in the development of organizations safety management systems. Internal safety audit is a method to appraise to the management the current status of occupational health and safety at workplace. Se...

Fault Tree Analysis is a traditional deductive safety analysis technique that is applied during the system design stage. However, traditional fault trees often suffer from a lack of formal semantics to check the correctness or consistency of the descriptions. This is especially a problem in safety-critical system analysis. To overcome this limitation, we propose a novel formal fault tree constr...

background: high-risk unsafe behaviors (hrubs) have been known as the main cause of occupational accidents. considering the financial and societal costs of accidents and the limitations of available resources, there is an urgent need for managing unsafe behaviors at workplaces. the aim of the present study was to find strategies for decreasing the rate of hrubs using an integrated approach of s...

Objective: This study aims to develop and create a tool based on factor analysis to assess safety culture in the processing industry. Methods: This study was conducted in the petrochemical industry in 2021. The questionnaires were distributed among 312 employees, supervisors, and managers, and 308 of them were completed. The validity of the questionnaire was assessed by content and construct v...

nuclear cross sections that determine core multiplication strongly depend on core temperature (e.g., the doppler, moderator density effects etc). on the other hand, since this heat is generated by the neutron flux in the reactor core, the temperature distribution in the core will depend heavily on its neutronic behavior. fuel centerline temperature could be the limiting constraint on reactor po...

this study focused on the public transport risk assessment in district one of ​​tehran through fault tree analysis involving the three criteria of human, vehicle and road in haddon matrix. in fact, it examined the factors contributing to the occurrence of road accidents at several urban black spots within district 1. relying on road safety checklists and survey of experts, this study made an ef...

Background & Aims of the Study: To prevent lots of work-related accidents in different industries and workplaces, managers should consider macro-factors such as safety culture and its elements like safety climate as the main subject to reflect attitude toward safety . This study aimed at finding the best work shift group in an Iranian process industry by safety attitude/climate...
