Abstract: (15 Views)
Background: Hearing protection programs are implemented to prevent and mitigate the progression of hearing loss resulting from noise exposure among workers. The benefits of implementing such programs directly contribute to maintaining and enhancing productivity levels, increasing work efficiency, reducing work-related accidents, as well as decreasing stress and fatigue associated with noise exposure. Therefore, this study was designed to prioritize and weigh factors affecting the performance of the hearing protection program using the Analytical Hierarchy Method (AHP) in the industry.to prioritize and weight.
Methods: The present study is a cross-sectional, descriptive, and analytical study that was conducted in 2021. It examined 4 criteria, including feasibility, efficiency, cost, and process interference, and 12 options, including environmental noise pressure measurement, sound mapping and iso-sonic with software, calculation of equivalent sound level based on ISO 9612 standard, assessment of workers' noise health risks, engineering control measures, managerial control measures, personal protective equipment control measures, determination of workers' hearing loss through audiometry, determination of changes in standard hearing thresholds, employee training, drafting an industry hearing protection program document, and monitoring the scientific quality of results of employees' hearing loss measurements. Finally, the final prioritization and weighting of criteria and options were done by the AHP method and through Expert Choice, V.11, and Excel software.
Findings: The results of this study indicated that the level of disagreement in all cases was less than 10%, and the compatibility of responses was confirmed. Among the criteria and options, the feasibility criterion with a relative weight of 0.658 had the highest importance, and the process interference criterion with a relative weight of 0.057 had the least importance. Furthermore, among the options, the option of measuring environmental noise pressure level with a final weight of 0.189 had the highest priority, and the option of sound mapping and iso-sonic with software ranked second. The option of assessing workers' noise health risks also obtained the third rank. Monitoring the scientific quality of results of employees' hearing loss measurements with a final weight of 0.017 was the least suitable option.
Conclusion: Nail technicians are exposed to concentrations of toluene and DBP in their workplace, and the risk assessment of dermal exposure to these compounds ranged from moderate to high. Based on the findings, researchers recommend that this group of workers use PPE such as appropriate gloves and masks. Additionally, future research should focus on the design and implementation of ventilation systems to improve safety for this occupational group.
