| Popis: | The article summarizes the data obtained in long-term research on working conditions estimates and studying damages to hearing organs in workers employed at petrochemical plants. We chose workers employed at five basic organic synthesis productions as an object of our study; these productions include ethylene-propylene, ethylbenzene-styrene, organic alcohols production (butanol and 2-ethylhexanol), phthalic anhydride. We detected that heating furnaces, compressors, and pumps were the main noise sources at the examined productions. Our research revealed that noise levels at the examined productions varied from 60 to 99 decibel, and calculated equivalent noise levels reached the 3 hazard class with 1st and 2nd hazard degree. Audiometric research showed that signs of impacts exerted by noise on hearing organs of workers belonging to basic occupational groups (processing machine operators and pumps and compressor operators) occurred authentically more frequently than in case of control equipment mechanics and automatic equipment operators (comparison group) ( |
