Noise Exposure of Workers on a Land Oil Rig Floor

Background: noise exposure is one of the most important problems in workplaces and general environments. noise exposures can have both auditory and non-auditory health effects.objectives: the aim of this study was to determine the noise exposure levels in oil drilling rig floor and camp facilities in ahvaz, iran. materials and methods: this was a cross-sectional study. environmental and personal noise exposure measurements were carried out by the method established by iso-9612 with a sound level meter and noise level dosimeter. results: all the measurements were performed in two parts of an oil drilling rig: the operation area and the camp area. the noise levels in 100 points in the rig area were between 54 - 110 db. the noise levels were also measured in 38 points in the camp area and ranged between 52 - 100 db.conclusions: our results showed that only 17% of the measured points in the oil drilling rig floor were in safe area; 39% were in caution area and 44% were in danger area. in the camp facilities area, 51% of the points were in safe area, 38% were in caution area and 11% in danger area. the main sources of noise exposure in the rig floor area were power generators.
