Background and Objectives: Safety climate in a workplace is the results of the values, attitudes, and individual and group interests, competencies and patterns of behavior which determines the commitment to occupational safety and health management in an organization, management practices and its effectiveness. Occupational safety and health management system (OSHMS) is an established system in an organization which has specific function in its subject. This study investigated the relationship between performance evaluations of this system and the results of measuring safety climate in an industry. Methods: The Australian OSHMS audit standard (AS OHS Audit tool) was used for OSHMS performance evaluation. It has 5 sections, 21 elements and 117 criteria each criterion gets score in the range between zero and 5 points. Safety climate was measured by Loughborough University Safety Climate Toolkit in which 17 dimensions are considered. Results: 7 out of 21 elements of OSHMS, did not get minimum score (i.e. score 2) required. Of 17 dimentions considered in safety climate, 9 dimentions did not obtain the minimum required score (i.e. score 6). But, in total the safety climate scores which had normal distribution, were consistent in different dimensions with the OSHMS performance evaluation points. Conclusion: The safety climate in this industry is highly influenced by the performance of OSHMS and can be considered as an indicator of the performance evaluation of this system.
