 Textile industries have various types of hazards that cause accidents. One of the ways to prevent workplace accidents is to identify hazards and evaluate them. Therefore, the present study aimed to evaluate the hazards of one of the textile companies using the Failure Mode and Effects Analysis (FMEA) method.

 This was a descriptive-cross-sectional study, and the FMEA method was used to conduct the study. In this study, two dyeing and rolling halls in the textile industry were evaluated. After calculating the Risk Priority Number (RPN), the hazards were ranked, and the necessary corrective actions were proposed. All stages of this research were conducted in accordance with ethical and research standards.

 In this study, 145 root causes of potential hazards were identified, of which 71 were recognized as high-risk hazards. The highest risk score was related to the non-functioning of the emergency stop switch. The lowest risk score was related to the steam leakage from steam pipes. The most hazardous activity was found to be the printing of dyes on the fabric. Events leading to death and amputation had the highest frequency.

 The results showed that after identifying the sources of error, it is possible to prevent the failures and increase the efficiency of the process by preventing damage to materials, operations, and personnel. The present study considers the FMEA method effective in assessing the hazards in the textile company. The results of this method can also be used to reduce the risk level to an acceptable level.

Today, it is essential to pay attention to the opportunities and threats in health services, especially in hospitals, to identify and evaluate the existing risks and manage them in these centers. Hospital risk management is a program to reduce the occurrence and prevalence of preventable accidents and is of great economic, human and moral importance in the hospital environment. This study aimed to evaluate and prioritize the occupational safety and health risks of the staff of Shahid Sadoughi Hospital in Yazd in 2019

The present study is descriptive-cross-sectional. In the first step, the main risks in clinical, laboratory, facilities, radiology, and administrative departments were identified. Based on FMEA logic, three severity, probability, and vulnerability indicators were identified for each risk. Then, prioritization criteria were determined, and ANP prioritized the risks.

According to infectious disease experts with a risk of 0.86 in the clinical ward, inhalation of Barisek chemical vapor 1.17 in the laboratory, radiation of the device with a risk of 0.64 in imaging, infectious disease with a risk of 0.33 and 1.3 in order of priority The first were in the administrative and facilities department.

The  results showed that the hospital  management should adopt special  management  programs to control infectious diseases with a staff  health approach. Control  measures should be set with priority risks. The difference in the obtained  risk numbers  indicated the different  priorities of implementing risk management  programs in each  ward of  Shahid  Sadoughi Hospital.

Safety, raising awareness, and preventing the occurrence of hazards are necessary in order to continue to improve the quality of laboratory activities, which have been recently considered by scientific, research, and industrial communities. Therefore, the present study was conducted to determine the risk factor, potential hazards, and provide practical programs in the laboratories of the Shrimp Research Institute.

Safety hazards of eight laboratories of the National Shrimp Research Institute were evaluated during the intervention study with the Failure Mode and Effects Analysis technique. To this end, in the first phase, the team of safety experts (HSE: Health and Safety Executive), by preparing and completing safety questionnaire forms, identified the current status of safety indicators and danger points of laboratories, assessed the distance with safety indicators, and managed danger points. Based on risk severity, probability of occurrence, and probability of risk detection, the risk priority number (RPN) was calculated, prioritized, and corrective measures were proposed. In the second phase, after corrective measures, the safety questionnaire was completed again and the level of risk severity, probability of occurrence, probability of detection, risk priority number, risk number, and percentage reduction of risk priority number of the studied laboratories were calculated and analyzed.

Thirty-five hazard points were identified in the laboratories. The range of risk priority numbers ranged from RPN = 12 for the Plankton Laboratory to RPN = 210 for the Marine Microbiology Laboratories and Marine Pollutants. After control measures, the risk number of marine microbiology laboratory was reduced to 180 and marine pollutants to 120 (P <0.05).

The results showed that FMEA technique is appropriate in identifying the risk points, evaluating, and classifying the risks of the Iran Shrimp Research Institute laboratories and provide control strategies to eliminate or reduce the risk rate of research environments.

Risk assessment is a systematic and essential procedure to determine the effects, events, and consequences of human activities on perilous systems. This study aimed to identify the hazards and determine the total risk of various units of Ilam Gas Refinery.

This descriptive-inferential study assessed the risks on 18 various units of Ilam Gas Refinery through a combination of Bow-tie and FMEA methods. Initially, the top event, threats, consequences, as well as preventive and recovery measures were identified using the Bow-tie method. Afterward, Risk Priority Number (multiplying severity, occurrence, and detection) was obtained by FMEA. Finally, the risk level was divided into three groups of low, moderate, and high crisis.

Based on Bow-Tie, the release activity of H2S gas was introduced as the top event. Furthermore, tank leakage and burst, corrosion and wear of pipes and fittings, human error, poor operating conditions, and natural factors in the threat role, as well as damages to human and environmental resources and financial losses were identified as consequences. Based on FMEA, the hazard of tank leakage and burst with two effects of human and environmental damages was in the level of high (major) crisis and was recognized as the most important hazard.

Gas refineries are faced with many hazards due to the nature of the work process. The integrated approach of Bow-tie and FMEA is a suitable method for risk assessment in such industries.

The main purpose of this study was to identify and evaluate environmental problems and their ranking and to determine the conceptual model of environmental impact assessment (EIA) in industrial parks. Accordingly.

In this study, environmental infrastructure issues were classified into five sections. The decision-making trial and evaluation laboratory (DEMATEL) technique was also employed to establish the relationships between the criteria. Moreover, the analytic network process (ANP) was utilized to determine their weight.

Examining the internal relationships between the variables correspondingly revealed that cultural and economic criteria were the most influential. On the other hand, the biological criterion was very effective. The ANP results also showed that the “low share of environmental investment” as an indicator was an economic criterion with a normal weight of 0.80, which was of utmost importance among the other defined cases.

It was concluded that the definition of conceptual models in EIA processes can make it possible to examine and analyze the criteria and indicators affecting evaluation processes.

 work-related accidents impose irreparable hurt on the national capital. It is necessary to take a series of preventive measures before the occurrence to preserve and protect the human force and reduce accidents. The current study aimed to check safety contradiction using the FMEA method and determine protection indicators of safety performance in the overhaul project. 

 This study is descriptive-analytical research and an interference method that accomplished 13 jobs in major repairs gas pipeline project. After determining jobs and entering them in the FMEA worksheet, the initial risk score was obtained in this investigation, and after corrective suggestions, the secondary risk priority score was calculated.

 The relationship between RPN1 and RPN2 was examined and determined a significant difference between risk priority score before and after corrective measure, and this indicates that these measures are effective (p<0.0005). Among various jobs and before taking corrective actions, the highest number of accidents was related to excavation activities with 15 accidents, which were reduced to 6 after taking corrective measures. Most days lost from work were related to driving job with 6020 days that reduced to 8 days after taking corrective actions; the highest rate of repeat accidents with 62.5 was related to détente activity reduced to 23.14 after taking corrective measures. The maximum intensity factor with 19444.44 was related to the driving activity reduced to 25.25 after taking corrective actions. The accident frequency - severity rate in driving activity with 15.84 was the most reduced to 0.28 after taking corrective measures. 

 Due to unacceptable risks and the high rate of accidents in the overhaul of the gas pipeline project, appropriate control measures can be used to reach an acceptable level of risk, which represents the usefulness of the FMEA method.

Renewable energies, such as wind and solar energy have attracted the attention of scientific, research, and industrial communities due to its fewer threats to the environment and human health. The purpose of this study was to identify and assess the safety and health risks of the Sun Air research institute of Ferdowsi University of Mashhad.

In this descriptive cross-sectional study, the failure mode and effect analysis (FMEA) technique was used to identify and assess the risks of all Sun Air Research Institute of Ferdowsi University of Mashhad units in the second half of 2019. The HSE management team identified the risks of each unit separately and assessed the risks. All risks were prioritized following identification based on the range of priority numbers (RPN) method resulting from multiplication of the Occupancy, Severity, and Detectability components as well as the control measures.

The RPN ranged from 18 cases related to repetitive work in inspection operations to RPN=180 related to electric current leakage. Among the risks, three potential risks had higher priority, which included electric current leakage (RPN=180), inhalation of toxic substances (RPN=162), and falling from a height (RPN=150). Other risks were ranked next in priority.

The results showed that use of FMEA technique was appropriate to identify and assess occupational risks in research and renewable energy production environments that lead to identification of risks at different levels. This helps the HSE team to eliminate or reduce the level of risks by providing control solutions with the priority of unacceptable risks.

Identifying occupational hazards and managing occupational safety and health risks has been the most important mission and responsibility of the health and safety management system in organizations and adopting coded plans to achieve this is the key to continuously improving this system and promoting it. The aim of the present study was to determine the optimal risk assessment methodology in development projects.

This was a descriptive-analytic research In this research, using previous research studies and collecting expert opinions, the most important criteria for selecting a specific risk assessment methodology, and then using one of the three most-used techniques is an important activity in the steel making industry and risk assessment. Then, the decision matrix is based on the strengths and weaknesses of the models. The prioritization of these three methods is done using the hierarchical analysis decision method.

In this paper, five key factors, the degree of application in identifying hazards, usability in different stages of risk assessment, reliability, ease of use, and training needs and costs, are identified as the most important criteria for choosing a risk assessment technique and the FMEA method was considered as the best  Risk Assessment Method.

FMEA methodhas been introduced with regard to its capabilities as an optimal risk assessment method for contruction projects.

Nowadays with increasing global competition, companies apply several scientific methods to identify, assess and remove potential failures in production process. The main goal of this study was identification and analysis of potential failure modes in a hydraulic pump manufacturing company by using combination of interval valued fuzzy Analytic network process (IVF-ANP), interval valued fuzzy failure mode effect and analysts (IVF-FMEA) and interval valued fuzzy TOPSIS.

First, potential failure modes of production process have been identified by applying opinion of experts. Then, failure modes have been prioritized by proposed method. Proposed approach applies the interval valued fuzzy ANP to determine the weight of each risk assessment factor and a combination of interval valued fuzzy FMEA and interval valued fuzzy TOPSIS for ranking the potential failure modes.

Totally, thirty failures have been identified. The first priority that was specified is inappropriate feed rate with number of 0.83 for relative closeness and the last priority failure is being large bush with number of 0.015 for relative closeness.

The results showed that the proposed approach is applicable for assessing and ranking of failure modes. In addition, consideration of some issues like cost factor, interdependence between risk assessment factors and also modeling the method under condition of interval valued fuzzy uncertainty, affected on the final ranking of failure modes.

Today, the drilling industry is one of the worldchr('39')s most dangerous occupations because of the many accidents it is facing. Therefore, the study and evaluation of the risks of activities and operations in the drilling industry can be helpful in reducing the accident in this industry.

In this research, the safety and health risk assessment of drilling operations was carried out in two drilling rig of No.28 national Iranian drilling companies and NO.101 drilling rig of oil companies using the FMEA method in Southern Yarran Oilfield. To identify unacceptable risks and provide a management solution to reduce the level of these risks

According to the results, 38% of the total risks are related to Lower risk, 33% refers to risks with a moderate level and 29% of the risks are related to the risks with a critical level. At this level, the risk of drilling rig operation with a total of 70 risks, the operation of cutting pipes with a total of 55 risks, and a sort operation with 26 risks, has the highest number of critical risks. Risks Repairs with a total of 127 risks, set up Rig with 100 risks and well scrolling operations with a total of 83 risk they were a part of the risk Count Risks Were high. Also, the highest frequency (L) of risks is related to repairs with a total of 99 risks and a pipe test with a total of 55 risks.

The main cause of these risks is the human error and the inspection of equipment and machinery. By providing control strategies, especially in two parts of the training of personnel, and creating more and more periodic and random inspections, can greatly reduce the level of the critical risks.

The oil and gas industries are considered as the most important industries in Iran, where a significant part of the budget depends on these two areas The significant health and safety implications of these industries on the staff and stakeholders have also been highlighted.

The present study was conducted to identify and assess the safety and health risks of the Fars Mountain Seismology project using HAZAN method in 2016 and 2017.  The hierarchical task analysis  (HTA) was used to analyze the main tasks of the main occupations: digger, surveyor, shooter, drivers, and helicopter pilot . The risk assessment process identified in the HAZAN method was based on the qualitative matrix.  In HAZAN, 50 health and safety risks were identified.

The results showed that eight risk factors (16%) were unacceptable, 25 were unsatisfactory (50%) and 17 (34%) were acceptable.

The results showed that the aviation and land transport processes as well as the traffic on mountain routes were the most expensive activities in the project.  Finally, management solutions were proposed to reduce the risk level related to the most important project activities
