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 female primary sc...

Since the 1985 release of methyl isocyanate in Bhopal, India, which killed thousands, the chemical industry has begun to use process hazard analysis techniques more widely to protect the public from catastrophic chemical releases. These techniques can provide a systematic method for evaluating a system design to ensure that it operates as intended, help identify process areas that may result in...

Research in asteroid detection and orbital characterization has identified a new class of possible natural disaster. Asteroids are the only known type of natural disaster that could potentially destroy civilization. The societal importance of asteroid detection is assumed to be high, given the destructive capacity of Potentially Hazardous Asteroids (PHAs). This paper offers a decision analysis ...

Abstract The evergreen process hazard analysis (PHA) is an essential next step in identification, risk analysis, and safety management. PHA addresses weaknesses practices that allow the facility to degrade become out‐of‐date during periods between 5‐year revalidations. This degradation has potential elevate facility. paper outlines prerequisites initial steps support moving PHA. Initial include...

The purpose of this study was to manage the risks of Paveh Rood Dam at constructional phase by integrating TOPSIS & RAM-D techniques. After investigating the environmental conditions of the study area and the technical specifications of the dam, the risks of the dam construction were listed in a questionnaire. After analyzing the given scores by Preliminary Hazard Analysis (PHA), Technique for ...

Hazard and operability (HAZOP) methodology is a Process Hazard Analysis (PHA) technique used worldwide for studying not only the hazards of a system, but also its operability problems, by exploring the effects of any deviations from design conditions. Our paper is the HAZOP review intended to gather HAZOP-related literature from books, guidelines, standards, major journals, and conference proce...

Unmanned Aerial Vehicles (UAV) technology has found its way into several civilian applications in the last 20 years, predominantly due to lower cost and tangible scientific improvements. In application structural bridge inspection, UAVs provide two main functions. The first, being most common, detect damage through visual sensors. 2 D image data can be used quickly establish a basic knowledge o...

The number of bioprocesses for the circular economy organic waste has grown in recent years. Implementation new processes and technologies should consider occupational health safety issues from initial design stages. Among process hazards analysis techniques, HAZard OPerability (HAZOP) methodology is widely used studying both process’s their operability problems, by exploring effects any deviat...
