Hazard and risk analysis in the logistics safety system based on international quality requirements

Publikacja prezentuje analizę zagrożeń i ryzyka w systemie bezpieczeństwa logistycznego prowadzonego na podstawie międzynarodowych wymagań jakościowych. Określono problem badawczy oraz pytania badawcze. Wskazano także cel badań, hipotezy badawcze, przedmiot i obszar badań oraz określono próbę badawczą. Przedstawione zostały definicje zagrożenia i ryzyka oraz metodyka analizy i procesu zarządzania nimi w przedsiębiorstwie. W dalszej części artykułu zaprezentowano miejsce analizy zagrożeń i ryzyka w międzynarodowych standardach jakościowych. Przybliżono mechanizm analizy ryzyka jako narzędzia zapewnienia jakości w brytyjskich, amerykańskich i polskich procedurach obronnych. Na koniec przedstawiono przykład wdrażania wymagań systemu zarządzania jakością dla przemysłu lotniczego, kosmicznego i obronnego w polskim przedsiębiorstwie. Analiza zagrożeń i ryzyka z nimi związanego na przykładzie i w oparciu o standardy międzynarodowe ma na celu uzasadnienie postawionych hipotez dotyczących wpływu analizy ryzyka na procesy decyzyjne w przedsiębiorstwie. Metody badawcze zastosowane to analiza przyczynowo - skutkowa, synteza informacji z zastosowaniem kojarzenia numerycznego i logicznego celem zebrania uporządkowanego materiału dowodowego. Rezultatem badań jest potwierdzenie postawionych hipotez dla procesu zarządzania ryzykiem. Proces zarządzania ryzykiem jest procesem ciągłym i wpływa na osiąganie celów strategicznych przedsiębiorstwa. Kluczowym czynnikiem dla faktycznego wdrożenia analizy zagrożeń i ryzyka w przedsiębiorstwie jest przeszkolony personel stosownie do zajmowanych stanowisk. Dodatkowym czynnikiem jest sposób zrozumienie i wdrożenie procesu zarządzania ryzykiem w przedsiębiorstwie.

Seismic Hazard and Risk Analysis

Seismic hazard and risk analyses underpin the loadings prescribed by engineering design codes, the decisions by asset owners to retrofit structures, the pricing of insurance policies, and many other activities. This is a comprehensive overview of the principles and procedures behind seismic hazard and risk analysis. It enables readers to understand best practises and future research directions. Early chapters cover the essential elements and concepts of seismic hazard and risk analysis, while later chapters shift focus to more advanced topics. Each chapter includes worked examples and problem sets for which full solutions are provided online. Appendices provide relevant background in probability and statistics. Computer codes are also available online to help replicate specific calculations and demonstrate the implementation of various methods. This is a valuable reference for upper level students and practitioners in civil engineering, and earth scientists interested in engineering seismology.

Elevated LNG Vapour Dispersion—Effects of Topography, Obstruction and Phase Change

The dispersion of vapour of liquefied natural gas (LNG) is generally assumed to be from a liquid spill on the ground in hazard and risk analysis. However, this cold vapour could be discharged at height through cold venting. While there is similarity to the situation where a heavier-than-air gas, e.g., CO2, is discharged through tall vent stacks, LNG vapour is cold and induces phase change of ambient moisture leading to changes in the thermodynamics as the vapour disperses. A recent unplanned cold venting of LNG vapour event due to failure of a pilot, provided valuable data for further analysis. This event was studied using CFD under steady-state conditions and incorporating the effect of thermodynamics due to phase change of atmospheric moisture. As the vast majority of processing plants do not reside on flat planes, the effect of surrounding topography was also investigated. This case study highlighted that integral dispersion model was not applicable as key assumptions used to derive the models were violated and suggested guidance and methodologies appropriate for modelling cold vent and flame out situations for elevated vents.

Probabilistic Tsunami Hazard and Risk Analysis: A Review of Research Gaps

Tsunamis are unpredictable and infrequent but potentially large impact natural disasters. To prepare, mitigate and prevent losses from tsunamis, probabilistic hazard and risk analysis methods have been developed and have proved useful. However, large gaps and uncertainties still exist and many steps in the assessment methods lack information, theoretical foundation, or commonly accepted methods. Moreover, applied methods have very different levels of maturity, from already advanced probabilistic tsunami hazard analysis for earthquake sources, to less mature probabilistic risk analysis. In this review we give an overview of the current state of probabilistic tsunami hazard and risk analysis. Identifying research gaps, we offer suggestions for future research directions. An extensive literature list allows for branching into diverse aspects of this scientific approach.

Design Cost Control in Risk Management with the Expected Money Value (Emv) and Hirarc Method at Pt Xyz Jawa Timur Surabaya

This Operation of production area A6 workshop in PT XYZ can protecally lead to risk of accidents due to contact between worker with machines that operate like geka machine. The accidents caused by companies not yet know how the potentially dangerous and risks of working in the garage area lathe, as well as the lack of good implementation of procedures before entering the work area. From the accident required a determinan of hazard and risk analysis on production A6 workshop conducted by using HIRARC (Hazard Identification and Risk Assessment Control) and conduct a risk assessment to provide an assessment of the result of multiplication Severity and Likelihood that refers to the Department of Ocupational Safety and Health Ministry Guidlines of Human Resources Malaysia
