“…İmportant measures must be taken to ensure the safety of the boilers. These measures include conducting annual inspections and tests of the boilers by qualified technical personnel, obtaining user manuals from the manufacturer or installer of the boilers, and ensuring that daily operation, maintenance, and inspection instructions are fully implemented by competent personnel (Landi et al, 2022).…”

Failure to implement adequate preventive measures in workplaces leads to the occurrence of occupational diseases and accidents at work. Effectively managing and accurately defining these risks is paramount. Risk assessment begins by assigning scores to identify existing workplace hazards, assess the likelihood of potential risks, determine the level of urgency, and determine the necessary precautions. It is a continuous cycle of implementation, monitoring and review. The aim of this study is the identification of existing or potential hazards and risks in a dairy products factory in Iğdır province, Turkey. The Fine Kinney risk assessment methodology was applied, and the results provided recommendations for mitigating identified risks based on relevant regulations. Initially, brainstorming sessions were held with relevant employees and managers to gain a general overview of the health and safety culture in the work environment. In addition, observational analysis and weekly checklists were used for assessment purposes. When examining the current status and operational procedures of the company in detail, various hazards containing risks that require immediate precautions have been identified. Electric shock (RS: 1440), injuries related to electricity (RS: 720), explosion (RS: 540), and risks associated with poisoning or drowning (RS: 720) have been determined to be present. It has been concluded that most of the environmental risks in the facility arise from factors such as defective or outdated equipment, lack of ergonomic workstations, inadequate training, and insufficient supervision.

“…The study raises the issue that in the analysis of this accident conducted by the Rail Accidents' Investigation Branch, they generally refrained from reviewing their own control actions contributing to the hazard [42]. Using novel approaches, such as CAST, accident analysis carried out by organizational and governmental agencies can reduce the subjectivity in selecting the chaining conditions and provide general recommendations to be absorbed by different levels of the SCS [43].…”

Learning from Incidents in Socio-Technical Systems: A Systems-Theoretic Analysis in the Railway Sector

et al. 2022

Post mortem incident investigations are vital to prevent the occurrence of similar events and improve system safety. The increasing interactions of technical, human and organizational elements in modern systems pose new challenges for safety management, demanding approaches capable of complementing techno-centric investigations with social-oriented analyses. Hence, traditional risk analysis methods rooted in event-chain reactions and looking for individual points of failure are increasingly inadequate to deal with system-wide investigations. They normally focus on an oversimplified analysis of how work was expected to be conducted, rather than exploring what exactly occurred among the involved agents. Therefore, a detailed analysis of incidents beyond the immediate failures extending towards socio-technical threats is necessary. This study adopts the system-theoretic accident model and process (STAMP) and its nested accident analysis technique, i.e., causal analysis based on systems theory (CAST), to propose a causal incident analysis in the railway industry. The study proposes a hierarchical safety control structure, along with system-level safety constraints, and detailed investigations of the system’s components with the purpose of identifying physical and organizational safety requirements and safety recommendations. The analysis is contextualized in the demonstrative use of a railway case. In particular, the analysis is instantiated for a 2011 incident in the United Kingdom (UK) railway system. Hence, the CAST technique requires information regarding incidents, facts and processes. Therefore, the case study under analysis provided the information to analyze the accidents based on system theory, in which the results of the analysis prove the benefits of a CAST application to highlight criticalities at both element- and system-level, spanning from component failure to organizational and maintenance planning, enhancing safety performance in normal work practices.

“…The fourth most crucial barrier determined in this study is 'Inadequate compliance with safety and hazard regulations (B11)'. The practice of conducting regular inspections of the boilers to ensure safety and regulatory compliance is not very common in emerging economies due to various technical, financial, and socio-economic constraints [20,41,63]. But, developed countries always ensure regular inspections by different government and non-government authorities to establish standard operational practices, thus minimizing environmental and safety hazards [64,65].…”

Evaluating barriers to sustainable boiler operation in the apparel manufacturing industry: Implications for mitigating operational hazards in the emerging economies

et al. 2023

The efficiency with which conventional boilers perform, in terms of sustainability, is affected by a variety of factors. Unsustainable boiler operating practices are still surprisingly frequent in developing countries, resulting in environmental liabilities and catastrophic accidents. It is a serious problem in developing countries like Bangladesh, where boilers are utilized extensively in the apparel manufacturing sector. However, no research has yet examined the challenges or barriers associated with sustainable boiler operation in the apparel manufacturing sector. This study, thereby, utilizes an integrated MCDM approach, combining the fuzzy theory and the decision-making trial and evaluation laboratory (DEMATEL) method, to identify, prioritize, and explore the relations among the barriers to sustainable boiler operation in the apparel manufacturing industry, from an emerging economy perspective. The barriers were initially identified from the literature and a visual survey of 127 factories. After expert validation, thirteen barriers were finally selected to be analyzed utilizing the fuzzy DEMATEL method. The study findings revealed that ’Absence of water treatment facilities’, ’Fossil fuel burning and GHG emissions’, and ’Excessive consumption of groundwater’ are the three most prominent barriers to sustainable boiler operation. The cause-effect relations among the barriers suggest that ’Inadequate compliance with safety and hazard regulations’ is the most influential and ’Fossil fuel burning and GHG emissions’ is the most influenced barrier. This study is expected to guide the managers and policymakers of the apparel manufacturing sector in successfully overcoming the barriers to sustainable boiler operation, thus mitigating the operational hazards and achieving the sustainable development goals (SDGs).
