Abstract
An occupational health and safety management system (OHSMS) demonstrates an organization's commitment to employee welfare and safety, benefiting the organization and employees for cost savings and reduced work accidents. The OHSMS is suitable for all types of organizations, but there are still many business establishments that do not yet have measures to practice and manage occupational health and safety. Therefore, this study aimed to determine the prioritization from OHSMS requirements including setting new optional requirements for use as OHSMS guideline based on the application of Analytic Hierarchy Process (AHP) and Fuzzy Analytic Hierarchy Process (FAHP). The study was conducted from August and December 2023. Data collection involved using standardized questionnaires, related to ISO45001:2018 requirements and additional requirements based on expert’s opinions. Delphi technique, Analytic Hierarchy Process (AHP) and Fuzzy Analytic Hierarchy Process (FAHP) were used for data analysis. The findings revealed that the leadership and worker participation were the highest of important weights, while the performance evaluation and improvement indicated the lowest of important weights. In addition, the new optional requirement apart from ISO45001 indicated that there were nine essential requirements of significance. These requirements included business competition in the market, product safety development, product pricing cost, modern machinery and equipment used for production processes, work experience, budget allocation for safety control and system supervisor, operations, compliance with laws and regulations, safety recommendations and hazard. Prioritization ISO45001:2018 requirements could use the implementation guidelines effectively. In addition, the inclusion of relevant new requirements also increased confidence in protecting the safety of employees.
