Comparative Evaluation of the Environmental Ergonomics Factors in Indoors of the Electronics Industry in Arid and Marine Environments of the Northwest of Mexico

Abstract

An investigation was made to evaluate the environmental ergonomics factors that had an effect on the operative yielding of workers of manufacturing areas of the electronics industry in two cities in the Baja California State of the Mexican Republic, such as the cities of Mexicali and Tijuana, located in the northwest of Mexico. These two cities represented in this scientific study two type of regions: arid in Mexicali and marine in Tijuana, and with this was made a comparative analysis, including the principal factors of the environmental ergonomics such as climate parameters (relative humidity and temperature), noise and vibrations of industrial machinery, level of luminosity in indoors of the ten industrial plants of the industrial electronics, which were evaluated .Also was analyzed presence of bad odors and inorganic air pollutants (derived from sulfur, nitrogen and carbon) and organic pollutants as microorganisms, provided from the enormous vehicular traffic and large number of industries in both cities. The presence of air pollutants mentioned above, caused the generation of Acute Respiratory Infection (ARI) in workers of the manufacturing areas and with this the productivity and quality levels decreased, due to the absence of experienced workers, and need use inexpert people that was making errors and with this, defective products manufactured. This investigation was made from 2018 to 2020, where in 2020 was made with a strict regulation by the presence of the Covid 19 pandemic.
