Background & objectives: Oil well drilling operations are subject to various occupational hazards because of their nature and type of activities, which causes illnesses, loss of workforce as well as a lot of financial losses to the economic system of the community. Therefore, it is essential for all employees to observe safety in order to protect manpower and equipment. The purpose of this study is to assess the occupational hazards of the drilling unit and provide the control measures to reduce the risk level of these hazards.
Methods: To this end, a list of probable safety and health risks was prepared and given to a number of drilling experts to confirm their accuracy. Then, considering the state of the risks, the overall risk options during the exploitation phase of drill rigs 28 and 101 were screened through the HAZAN form.
Results: The results showed that 48% of the total risks were in grade 1 (acceptable), 29% in grade 3, 22% in grade 2 and 2% in unacceptable rating.
Conclusion: The results showed that the acceptable risks were at the highest percentage, pointing the fact that using more engineering controls can lead to risk control, and also, within a reasonable time, the level of risk of 1 and 2 ratings can be reduced to 3 or 4. Furthermore, welding activities, drilling operations and drilling start-up were among the top three priorities of unacceptable risk-taking level which created the most occupational hazards for the industry. |
