Background and aims: Academic laboratories are considered as environment for performing various laboratory processes. Physical, chemical, biological and mechanical stressors are common in laboratory environment. The purpose of the study was to provide a comprehensive health, safety and environmental risk assessment in an academic laboratory. Methods: A case study design was conducted. The re...
Background and aimsSafety is a complex concept and multidisciplinary science which is included some difference areas from industrial sectors to urban public arenas. Parks and playgrounds as important public places should be considered in terms of health and safety, especially for kids as prominent social vulnerable citizens. According to CPSC, 147 deaths havebeen reported for under 15 year old ...
Introduction: Safety behavior is actual behaviors that done in accordance with safety instructions and it consists of both safety compliance and safety participant. Safety behavior assessment and identification of its related factors in the local labor communities is an important step in reducing accidents. This study aimed to evaluate the safety behavior and its predictive individual and occup...
Background and Aim: Millions of occupational accidents and disease cases are reported from work places annually causing considerable human and financial damages. Safety training is globally considered the best strategy to mitigate these damages. In this project a safety attitude questionnaire was used to obtain the required information. The questionnaire contained items about 13 relevant varia...
Background and aim: hazardous materials transport is one of the most important problems in developing countries. The accidents involving the fleet of hazardous materials transport can have irreparable consequences. The study was aimed to present safety performance assessment pattern of road trucks with risk assessment approach. Methods: This is a descriptive study. In this study, the Accidents...
-Fuzzy theory is integrated with Artificial Neural Network to create a bridge safety assessment model, through which the Fuzzy-Neural Network is improved in the light of sample data simulation. First, determine network layers interms of the seven critiria for bridge safety assessment. Then enter sample data at the input layer; study sample at the fuzzy reasoning layer by BP calculation method; ...
Safety risk management has a considerable effect on disproportionate injury rate of construction industry, project cost and both labor and public morale. On the other hand time-cost optimization (TCO) may earn a big profit for project stakeholders. This paper has addressed these issues to present a multi-objective optimization model to simultaneously optimize total time, total cost and overall ...
The paper presents the development of an intelligent railway safety risk assessment based support system. The proposed method can evaluate qualitative and quantitative safety risk data and information in a uniform manner for railway safety risk assessment. It permits the safety risk analysts to assess the risks associated with the failure modes directly using linguistic terms, i.e. qualitative ...
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...
