“…In the next step, to measure the harmful occupational health agents for the different company job groups, the instructions approved by the Ministry of Health and Medical Education (MHME) were used in Table 1 . In the next step, we combined Noise control priority index (NCPI) ( 15 , 16 ) and Comprehensive Occupational Health Risk Assessment (COHRA) ( 7 ) with two purposes and provided the Harmful Agent Risk Priority Index (HARPI). 1) Using COHRA to determine each harmful agent’s weight factor and eliminate their unit (dimension) to compare all agents’ priorities ( Table 2 ) 2) Using NCPI to consider the parameters of exposure time and the number of workers exposed to pollutants ( Table 3 ).…”

“…They have led to serious concerns for the ILO and related organizations ( 6 ). One of the most important factors influencing the improvement of health and safety management is developing and implementing risk assessment methods to ensure the achievement of health and safety programs 7 ).Risk management is legally required in some countries, such as the United Kingdom and Singapore ( 8 ). To minimize the potential conflict between work and family, implementing effective safety and health management systems, focusing on improving workplace occupational health, can be beneficial ( 9 ) .…”

Background: Considering the necessity of health risk management, the present study conducted to provide a comprehensive model for identifying, evaluating, and prioritizing occupational health risks in an oilfield. Methods: We conducted this descriptive-analytical cross-sectional study in 2022 at the North-Azadegan oil field in Iran. The occupational health risk was assessed using the "Harmful Agents Risk Priority Index" (HARPI) method. Results: Among the employees for the office section in all job groups, ergonomic risks due to people's posture while working has the highest risk score and is the most critical risk for implementing corrective actions. In the operational section, for the HSE group, benzene, the production group, Electromagnetic Fields (EMFs), and other groups, undesirable lighting has the highest risk score, and exposure to Toluene, Ethylbenzene, Xylenes (TEX) has the lowest risk score. In this oil field, controlling exposure to benzene, correcting ergonomic conditions, and controlling noise exposure, with scores of 81.3,74.85 and 71.36, have the highest priority, respectively. Sequentially, Toluene, Xylene, and ethylbenzene, with scores of 10.25,11.61, and 11.61, have the lowest control priority. Conclusion: The proposed model can prioritize the workplaces' harmful agents based on the HARPI score due to exposure to chemicals, physical factors, and analysis posture.

Background: Despite huge advances in science, technology, and medical equipment, numerous concerns grow over healthcare workers (HCWs) since they are exposed to a wide range of biological hazards due to the nature of their work. Objectives: The current study aimed at developing and validating an index to assess the risk of occupational safety and health (OSH) in hospitals and healthcare settings. Methods: In the current cross-sectional study, an index called the hospital occupational safety, and health risk assessment (HOSHRA) was developed and validated through the face and content validity as well as internal consistency and inter-rater reliability. Ultimately, the developed index was utilized to assess OSH risks in 36 teaching hospitals affiliated to Shiraz University of Medical Sciences, Shiraz, Iran. Results: The mean score of the HOSHRA index among the selected hospitals was 71.53 ± 5.93, indicating that the OSH risks were at a moderate level. According to the HOSHRA action levels, OSH risk level for ergonomic hazards was high, but it was moderate for physical, chemical, ergonomic, and psychological ones. In terms of physical hazard subcategories, the risk of electrical hazard, as well as fire and explosion, was high, but it was moderate for fall and slip, and radiation. Conclusions: The developed observation-based method showed an acceptable content validity and reliability for OSH risk assessment of hospitals. The HOSHRA index could also be used for hospitals as an applicable measure to improve their OSH.

“…Li et al (17) proposed a new method of occupational health risk assessment based on Set Pair Analysis, which could assess the comprehensive risk of welding workshops. Jahangiri et al (18) used a comprehensive occupational health risk assessment model to prioritize occupational health hazards in petrochemical companies and to determine resource allocation and required control measures. Ji et al (19) in New Zealand revised the conventional risk assessment approach to a comprehensive risk assessment method that considered both safety accidents and chronic health issues, providing a way to incorporate longterm health outcomes into occupational health risk accessment.…”

BackgroundOccupational hazards such as solvents and noise in the electronics industry are serious. Although various occupational health risk assessment models have been applied in the electronics industry, they have only been used to assess the risks of individual job positions. Few existing studies have focused on the total risk level of critical risk factors in enterprises.MethodsTen electronics enterprises were selected for this study. Information, air samples and physical factor measurements were collected from the selected enterprises through on-site investigation, and then the data were collated and samples were tested according to the requirements of Chinese standards. The Occupational Health Risk Classification and Assessment Model (referred to as the Classification Model), the Occupational Health Risk Grading and Assessment Model (referred to as the Grading Model), and the Occupational Disease Hazard Evaluation Model were used to assess the risks of the enterprises. The correlations and differences between the three models were analyzed, and the results of the models were validated by the average risk level of all of the hazard factors.ResultsHazards with concentrations exceeding the Chinese occupational exposure limits (OELs) were methylene chloride, 1,2-dichloroethane, and noise. The exposure time of workers ranged from 1 to 11 h per day and the frequency of exposure ranged from 5 to 6 times per week. The risk ratios (RRs) of the Classification Model, the Grading Model and the Occupational Disease Hazard Evaluation Model were 0.70 ± 0.10, 0.34 ± 0.13, and 0.65 ± 0.21, respectively. The RRs for the three risk assessment models were statistically different (P < 0.001), and there were no correlations between them (P > 0.05). The average risk level of all of the hazard factors was 0.38 ± 0.18, which did not differ from the RRs of the Grading Model (P > 0.05).ConclusionsThe hazards of organic solvents and noise in the electronics industry are not negligible. The Grading Model offers a good reflection of the actual risk level of the electronics industry and has strong practicability.
