Effect of Occupational Health and Safety Management Standards and Environmental Management on Environmental Factors and Employees Satisfaction at MILAD Industrial Complex - Before and After Study

Defense organizations increasingly interested to achieving of the occupational health and safety performance through controlling the risks goals and safety policy. This study aimed to effects of the establishment of occupational health and safety management systems on the environmental factors and employees satisfaction. This study was quasi-experimental and type of before and after approach. This study was performed in the MILAD industry complex in year of 2012. Data collection used by data collection form and the structured questionnaire and validity and its reliability were confirmed (α =%81). The study population using Cochran''s formula included 100 of employees which were formed by random sampling. The results showed that the mean level of sound intensity of 54/79 dB 51/72 dB were reduced، intensity stations in the limit of (8/30% to 4/70%)) increased، chemical agents from 2/14 to 4/11 mg/m3 is reduced، mainly gaseous CO (from 143/0 to 062/0) input CO (from 28/9 to 49/7). The effect of these systems on heterogeneous، there are some environmental factors so that the positive effect of sound intensity at four plants in one of the factories had no effect.
