Acceleration associated with mechanical vibrations on drilling rigs during drilling and in similar mining equipment have harmful effects on workers present at their work stations. This adverse condition coexists together with other numerous environmental factors characteristic for the activity of drilling equipment. Drawworks, combustion engines, mud pumps, electrical generators, shale shakers, pneumatic grinders are mechanisms creating different kinds of vibrations during their work. It happens, that vibration amplitude exceeds allowable values of obligatory standards or legal regulations, and puts workers at risk of health loss. In order to determine the magnitude of vibration, measurements and tests are performed periodically mainly at work stations. Whole body vibrations (WBV) (transmitted to the human body through his legs, pelvis, back or shoulders) and hand-arm vibrations (HAV) (acting through hands) have been measured and interpreted. The main parameters characterizing the harmful factors acting on workers, such as: permissible values of vibration acceleration, permissible exposure time have been calculated and compared with measured values. Ratios of measured vibration values to Occupational Exposure Limits (NDN) were evaluated. A comparison of the changes in the NDN index that took place in 2005–2016 at work stations for selected drilling equipment was made. The publication discusses the issue of mechanical vibrations occurring at work stations. Pilot vibration surveys were performed according to the requirements described in Polish regulations and appropriate EU documents. By comparing measured vibration values with OEL, the degree of their harmful effect was determined. In order to facilitate and accelerate calculations, a spreadsheet was prepared. Elaborated measuring and interpretation methods were implemented in the form of a spreadsheet and are currently used to evaluate mechanical vibrations in oil industry plants and in other similar industries.
