| Production process in The National Iranian Drilling Company like other industrial environments is associated with various safety, health, hygiene and ecosystems risks due to the nature and type of such activities. As a result, there is the Possibility of harm to humans, equipment and the environment. Therefore, the current study was done on evaluation of risk, safety, health and environmental management to identify possible hazards, risk rate, control and reduce the level of risk and in line with health maintenance personnel, equipment, capital and environment. In this study “William Fine” method was used in which the organized and systematic risk assessment techniques in recognition of the potential hazards and estimate the level of risk in order to manage risk was used. For this purpose, after identifying the activities and processes of the company, risks and potential damage was identified and then depending on the severity of the impact, the probability and its possible implications for human exposure, environment and, assessment on the risk was performed and classified. : Level of safety hazards for health in warehousing activities in pressure cylinders was the highest risk level with a score of 400. The lowest risk level was associated with safety in handling operations and delivering well in the courtyard. The highest and lowest rate risk on the Environmental aspects is respectively related to the supplementary operations with the score of 384 and establishing drilling machine with the score was 24. Due to the high probability of occurrence, the severity of the effect and exposure and, therefore, high risks, it is essential that special attention is paid to the industrial unit to prevent the risk and predict the necessary facilities. |
