We give a model for hazard analysis of user-interaction based on HAZOP. We consider the role of formal speciication and user-interface design in such a hazard analysis. Formal speciications can be used to describe tasks, while the user-interface design describes executions to eeect tasks. We illustrate the user-interface hazard analysis process by considering execution errors for a \data-link" ...

In this paper we present a HAZOP Assistant based on D-higraphs, a functional modeling technique that gathers functional and structural information of the process under study. The Assistant and the methodology are presented and applied to an industrial case: H2S absorption and DEA regeneration. Its results are compared with other existing techniques showing that the Assistant fills the gaps and ...

Hazard and operability analysis (HAZOP) is the paradigm of industrial safety that can reveal hazards process from its node deviations, consequences, causes, measures suggestions, such be considered as hazard events (HaE). The classification research on HaE has much irreplaceable pragmatic values. In this paper, we present a novel deep learning model termed DLF through multifractal to explore wh...

The Pulverize is a major part of the boiler combustion system and an important part in the system of steam power plant (PLTU). Pulverizer plant serves to break chunks of coal into the coal ash was then fed to the burner. Type of feed coal into a pulverize is cleaned with a value product pulverize optimum 30%. The percentage of this value greatly affects the production of steam in the boiler. Th...

The size and complexity of industrial chemical plants, together with the nature of the products handled, means that an analysis and control of the risks involved is required. This paper presents a methodology for risk analysis in chemical and allied industries that is based on a combination of HAZard and OPerability analysis (HAZOP) and a quantitative analysis of the most relevant risks through...

Safety analysis (SA) procedures, such as Hazard and Operability analysis (HazOp) and Failure Mode and Effect Analysis (FMEA) are generally regarded as repetitious, time consuming, costly, and require a lot of human involvement. Previous efforts have targeted automated support for SA at the design stage of system development. However, studies have shown that the cost of correcting a safety error...

BACKGROUND The aim of this study was to identify the hazards, evaluate their risk factors and determine the measure for promotion of the process and reduction of accidents in the chemical unit of the power station. METHODS In this case and qualitative study, HAZOP technique was used to recognize the hazards and problems of operations on the chemical section at power station. Totally, 126 devi...

The safety and environmental aspects of a manufacturing process are important due to increased environmental regulations and life quality. In this paper, the concentration of aerosols in the breathing zone of the operator of Electrical Discharge Machining (EDM), a commonly used non traditional manufacturing process is presented. The pattern of aerosol emissions from this process with varying pr...

Risiko kecelakaan kerja pada proyek konstruksi merupakan risiko yang tinggi, namun terkadang faktor-faktor dapat mengurangi masih kurang mendapatkan perhatian. Menurut Peraturan Menteri Pekerjaan Umum Nomor : 05/PRT/M/2014 Bab 1 Pasal Sitem Manajemen Keselamatan dan Kesehatan Kerja Konstruksi adalah bagian dari sistem manajemen organisasi pelaksanaan pekerjaan dalam rangka pengendalian K3. Pene...
