Abstract:

PT. X works in the automotive manufacturing industry. There are various departments in the corporate structure, one of which is K3 (Occupational Health and Safety). This department is an important part of a company. Bearing in mind that all machines and equipment used have potential hazards. Therefore, the purpose of this research is to examine the risk of work accidents that endanger the safety and health of employees. To control the potential for work accidents, the HAZOP method was chosen. The HAZOP approach was used to conduct this research. Hazard and Operability Studies (HAZOP) was found

Em função das catástrofes em barragens de rejeito alteadas a montante no Brasil e consequente necessidade de descontinuidade destas instalações, as Estações de Tratamento de Efluentes Industriais (ETEIs) revelaram-se como substitutas viáveis para empresas dependentes deste processo. A implementação adequada de uma ETEI deve envolver uma avaliação detalhada de riscos, uma vez que o acometimento de falhas pode paralisar toda a operação de uma planta. O objetivo deste artigo é aplicar o HAZOP em um projeto de uma ETEI, em uma mineradora de grande porte, de forma a avaliar a contribuição na reduçã

Abstract:

The HAZOP procedure is a common brainstorming method used to identify deviations in the operation of potentially hazardous equipment, their causes and consequences. As a result of the HAZOP session, the possibility of an emergency depressurization of the equipment can be es-tablished. Despite the thoroughness and consistency of the HAZOP study, it is still a common practice to qualitatively assess the impact of deviations on subsequent processes in emergency equipment. This approach is the main reason for the high probability of errors, especially when studying complex technological systems. M

Abstract:

Hazard and Operability (HAZOP) is the most widely used safety evaluation method because it systematically reviews the causes and results of all abnormal deviations in chemical plant facilities. However, fires and explosions caused by human error occur frequently. This study combined HAZOP and JSA, a chemical plant risk assessment technique, to determine the effectiveness of preventing significant industrial accidents whereby fires and explosions injure workers. The effectiveness of the 96-step distillation container cleaning process was assessed by identifying risk factors, using three differe

In production systems, HAZOP is an example of such approaches that were suggested to identify, analyze, assess and control industrial risks. Unfortunately, HAZOP is not supported by methodological guidelines to implement it. Also, HAZOP does not rely on core concepts that allow the design of computerized toolkits that could be integrated within enterprise information systems to store and reuse knowledge stemming from the implementation of HAZOP projects. In this paper, we suggest an artificial immune based methodology to assist experts in implementing HAZOP projects. Through a case study, we s

Abstract:

Traditional hazard and operability analysis (HAZOP) is one of the most widely applied methods for process safety management in process enterprises. Due to its principles based on the conservative and qualitative judgment, it often leads to too conservative risk identification results for the fluorine chemical industry usually with high-risk processes to keep the continuity of production. Most of improved quantitative and semi-quantitative methods are based on the layer of protection analysis (LOPA) to resolve the over-conservative problem of traditional HAZOP with the database of LOPA.

Abstract:

HAZOP hazard identification method, which considers the parts of a system individually, has disadvantages that limit its application to structurally complex technological systems. In these cases, the simplified risk analysis methods such as FMEA, FMECA, etc. cannot be correct. To assess the risk of complex systems, it is recommended to conduct additional studies using the methods such as FTA and ETA, and other more rigorous methods. Additional studies require a significant investment of time, which is often limited by design time. Limitations can be overcome by using the information technology

Abstract:

Increasing automation is a major trend in container terminals. In automated container handling systems, safety has been previously ensured by segregating the automated machinery from other traffic and workers moving on foot. Currently, further increases in flexibility are sought by developing autonomous systems that are capable of mixed-traffic operations without the need for separate operating areas. This increases the complexity of the systems and introduces new safety hazards. In addition to traditional hazard analysis methods, new approaches are needed to address the emergent risks related

Abstract:

This study explores using HAZOP analysis to assess risks in emergency logistics during epidemics. It highlights the importance of various aspects like personnel training and material management in different stages (preparation, rescue, and recovery) of emergency logistics. The study identifies critical risks through HAZOP analysis and proposes countermeasures like improved training and optimized resource allocation to mitigate these risks and improve overall efficiency. This research provides valuable guidance for building more robust emergency logistics systems to better respond to future out

Abstract:

Many companies follow very systematic methodology for carrying out execution of Mega projects. Project risks are identified, analyzed and proposed mitigation actions are identified and agreed upon. This activity is carried out in Project Risk Workshop. While SIL and HAZOP workshops are broadly related to the process design. HAZOP technique is a highly disciplined and systematic in nature; it attempts to identify how a process may deviate from the design intent. The emphasis in the HAZOP study is on identifying potential problems, not necessarily solving them. SIL studies is a specialized area

Abstract:

The purpose of this work is the risk assessment of a stabilizer reflux drum using HAZOP - Fault tree - Event tree approach. This risk assessment approach aims first of all to identify potential accident scenarios using Hazard an Operability study (HAZOP), these scenarios need more detailed frequencies estimation, it is performed thanks to fault tree analysis. Then, to analyze events issuing after success or fail of safety barriers, the event tree is used. Finally, in order to better appreciate accident scenarios, ALOHA is utilized to simulate them.

Abstract:

In the field of chemical safety, a named entity recognition (NER) model based on deep learning can mine valuable information from hazard and operability analysis (HAZOP) text, which can guide experts to carry out a new round of HAZOP analysis, help practitioners optimize the hidden dangers in the system, and be of great significance to improve the safety of the whole chemical system. However, due to the standardization and professionalism of chemical safety analysis text, it is difficult to improve the performance of traditional models. To solve this problem, in this study, an improved method

Abstract:

Introduction: The article addressed the integration between process simulation and HAZOP studies as a tool for risk analysis in the chemical industry. It was identified that, despite the effectiveness of traditional HAZOP, its qualitative nature and dependence on expert judgment limited its scope in complex systems. In response, it was proposed to review the use of simulation - in steady state and dynamic - as a support to improve the identification and evaluation of deviations in industrial processes, especially in CSTR type reactors.Development: The principles of chemical process simulation

Abstract:

Hazard and operability study (HAZOP), which is applied to identify the hazards of a system and its operability, finds application in identifying unsafe behaviors of operators after redefining the “guide words” and “process requirements”. In this paper, unsafe behaviors of lifting workers on the construction site and the risk they brought were identified using the redefined HAZOP. Then, the causes of these behaviors were revealed after sorting and analysing these behaviors.. Finally, based on these causes, appropriate management measures were developed for effectively reducing accidents in lift
