Evaluate the Effects of Establishing Occupational Health and Safety Management Standards and Environmental Management on Environmental Factors and Employee Satisfaction

This study aimed to investigate the status of the establishment of occupational safety and health management system and environmental management system on environmental factors and employee satisfaction. This paper was a quasi-experimental study of before and after type that was conducted in 2012 in Milad Industrial Complex based on the results of measuring occupational and environmental pollutants. Data collection was structured through a form and a questionnaire. The validity of the questionnaire was confirmed by content validity and reliability by Cronbach's alpha (r = 81%). The statistical population of the study using Cochran's formula (α = 95%) consisted of 100 employees by random sampling method. After the installation of the systems, the average sound intensity decreased from 54.79 dB to 72.51 dB, the percentage of stations with the allowable light intensity increased from 8.30% to 4.70% and the number of gases and vapors Decreased from 14.2 to 11.4 mg/m3. In the evaluation of the number of suspended particles, carbon monoxide was reduced from 0.143 to 0.062, and carbon dioxide from 0.28 to 7.49 and was within the standard range. Employees' satisfaction analysis of the environmental conditions showed that the majority of employees in the statistical community (88.7%) are satisfied. The simulation results show that with the establishment of occupational safety and health management systems, environmental factors in the organization are controlled and with the improvement of environmental conditions, employee satisfaction increases and individual and organizational performance improves.
