Abstract

An investigation of the negative effects in the health of workers of a metallic industry located in Mexicali city was made in which they suffered daily, of discomfort in the head, neck, back, and spine. This occurred when people of the manufacturing area of the industry that was evaluated developing operations that required great physical effort without adequate equipment and the industrial operations were repetitive. The analysis was made in 100 workers (30% women and 70% men) and were evaluated in the morning and evening shifts, which performed functions of lifting, loading, and gluing pieces of window frames for homes made of aluminum material. The aluminum frames had a weight of 20 kilograms with repetitive operations of until 50 lift for each eight-hour shift, generating the discomfort and pain. The study was from 2017 to 2019, and more than 50% of the workers in the manufacturing areas, in the two shifts of the company, suffered from discomfort and pain in the mentioned body areas, which caused the concern of management and supervision personnel.

Introduction

An evaluation was made, at the time it was detected a risk situation of workers which operated in the area of cut and gluing aluminum materials was made, which is used especially in houses of social interest in the Mexicali city, where are required thousands of frames to the construction activities (CEC, 2006). These industrial processes are high risk when they do not have the appropriate equipment and tools, with operations repetitively, and in addition to not elaborate these industrial activities. Other factor was the elaboration of the industrial processes without an ergonomic method and with inappropriate posture, which initiated a small nuisance in the aforementioned body areas previously (G. Wallace, 2011). Of the 100 workers evaluated, at least five of each turn of each day, and this is 45%, were missing from one to two days, due to inconvenience, which resulted in staff turnover of the same company or hiring of new workers (Houshang Alamdari, 2017; Robson LS et al, 2011). The management and supervisory personnel were concerned that this caused errors by new personnel in this area and those were not trained were susceptible to suffering from a health symptom mentioned above. This contributed to delays in the fabrication in any area of this industry and in to the customer, and the customer requesting financial compensation for the delay of the finished product.

Occupational Health vs Industrial Operations

Industrial operations of a manufacturing area were evaluated, with rigid activities and with a high risk to suffer discomfort and pain in dorsal parts mentioned above of the body of workers. When analyzing the lift, charge and sustain metallic pieces used to fabricate the frames of windows, was observed that this industrial operation not was made with an ergonomic manner required, which generated that the employees suffered a negative effect on their health with discomfort and pain essentially head, neck, back and spine (Leticia Arenas-Ortiz et al, 2013). Even when the employees of the company were constantly trained, the lack of awareness of the personnel to elaborate the operations in an adequate way, caused that the workers continued to suffer from discomfort and pain in the mentioned areas of the body, and it was necessary generate the staff rotation continuously (Sierra OA et al, 2010) . According to the General Mexican Health Institution, about 15,000 workers suffer from dorsal diseases a year (IMSS, 2018). The constant repetitiveness of movements of lift, charge and sustain the metallic pieces, originated inadequate postures of workers in the welding process, and this increased up to 75% the number of employees in this area, with visits to the doctor of the company where the investigation was made, and visits to the Mexican hospitals located in the city of Mexicali. In addition, it caused that some people failed to his job for a few days, and in certain employees not work and need visit the Mexican health institutions. This caused extra costs to the company due to this situation, and originating a rotation of personnel in manufacturing area evaluated, generating errors, which caused concern in the supervisory staff and managers of this evaluated industrial plant (Joan Burton, 2010). The concern was greater when certain aluminum frames arrived at the places where were used in the private residential with dimensions uneven, and it was a problem in the construction of homes. The health symptoms in workers caused two concerned diseases as cervicalgia and epicondylitis that generated an inability of workers, being a high risk in the workers of the manufacturing area analyzed. The information of the industry, and was correlated with information of data from visits to the medical institutions and records of health institutions in Mexicali.
