Niveles de exposición de ruido laboral en el área de calderas de la primera fábrica de balanceado para camarón de origen china en el Ecuador.

Abstract

This study analyzes noise exposure levels in the boiler area of the first Chinese-made shrimp feed mill in Ecuador. The research aims to evaluate the impact of noise on workers' occupational health and propose mitigation strategies to reduce associated risks. The population consists of workers in the boiler area, who are constantly exposed to high noise levels. A quantitative methodological approach was used, with a descriptive design and probability sampling. Measurements were taken with sound level meters at different strategic points in the plant, following Ecuadorian regulations and international standards. The results show that six of the eight areas evaluated exceed the 85 dBA limit, established as a safety criterion. The pre-milling area recorded the highest level at 106.7 dBA, representing a significant risk of hearing loss. In addition, improper use of hearing protectors and deficiencies in hearing safety training were identified. It is concluded that it is essential to implement control measures such as the installation of acoustic booths, improvements in machinery maintenance, and strengthening staff training. The implementation of these strategies will reduce noise exposure and improve the safety and health of factory workers.
