The safety culture that prevails within an organization and the way in which the latter addresses and manages safety problems has a significant influence on the safety-related behavior of people in the workplace. For that reason, it is essential that every organization is able to identify and objectively evaluate the factors that influence safety culture. This research paper seeks to identify the factors that affect safety culture and establish a qualitative rating scale for each. Consequently, the appropriate knowledge of each of these factors suggests more objective, accurate and effective safety actions. The review of prior objective European research led to the development of a proprietary methodology in order to design a tool that is applicable to the local environment that currently lacks one. The end result achieved was a questionnaire addressed to the workforce, which evaluated 3...

La Cultura de Seguridad que prevalece dentro de una organización, la forma en que esta aborda y gestiona los problemas de seguridad, es una influencia importante en el comportamiento que tiene relación con la seguridad de las personas en el trabajo. Por ese motivo, es esencial que cada organización pueda identificar los factores que inciden en ella, y que además los evalúen objetivamente. El presente trabajo de investigación propone identificar los factores que inciden en la Cultura de Seguridad y la posibilidad de establecer una escala de calificación cualitativa para cada uno de ellos. Así, del conocimiento adecuado de cada uno de estos factores se sugieren acciones en seguridad más objetivas, certeras y efectivas. La revisión de trabajos europeos previos, orientada a lo objetivo, dio lugar al desarrollo de una metodología propia para diseñar una herramienta aplicable al me...

The research, conducted on a microtextile manufacturing workshop allowed the approach of university life with the reality of micro enterprises in the Northern Cone of Lima. First diagnosis microenterprise is made, both in terms of production process and commercial. A workshop was found whose operations are conducted in a relatively small space, without corresponding data sheets. The implementation of 5S had the active participation of the owner and staff of the micro enterprise, the same that had the most runtime in the first three S (select, seiri, organize, seiton; and clean, seiso). The central finding of the research is positive and significant change in the perceived quality of the staff of the micro enterprise, realizing the importance of the implementation of this tool.

The objective of this applied research is to demonstrate the decrease in environmental pollution and occupational exposure by systematizing the iron ore dust control process at the San Nicolás benefit concession crushing plant of mining company Shougang Hierro Perú S. A. A. The causal relationship between environmental pollution and occupational exposure was established via the measurement of particulate matter. Perception of environmental pollution reduction was measured using a quantitative approach in a sample of 15 workers and data processing by means of descriptive and inferential statistical methods. The results show that the average level of influence of the iron ore dust control system is significant, at a confidence level of 95% and significance level of 5%. Therefore, the system efficiently reduces air pollutant values. Prior to implementation, the air pollutant value was 500...

Chromium salts are chemical reagents widely used in the tannery industry because they are efficient for tanning animal skin, however, these salts are not completely fixed, so their remnants go to their effluents, seriously impacting the environment. The objective of this study was to remove chromium (VI) and total chromium from a tannery effluent using electrodialysis, for this purpose, a sample of an effluent from a tannery pilot plant was characterized and then a synthetic solution was prepared based on this, using an industrial grade chrome salt for tannery, then the limiting current was determined and electrodialysis tests were carried out with the 80, 100 and 120% of the limiting current. The results showed that the highest percentage of extraction and the lowest electricity consumption was 80% of the limiting current.

Applies philosophical pragmatism current combining Sustainable Development Objectives Competences: Self-awareness of environmental value in order to contribute with NFU Reuse forms integrated to collaborative work in (PEI) Institutional Educational Project Land of Children and Adolescents (TINI); as a curricular requirement in medium-level educational units in Ecuador contributing to the improvement of the environment. The Tire Reuse Program of the Ministry of Industries and Productivity Ecuador, estimated that 300 thousand tires are destined to dumps or other sites and after the execution of the TINI recovered approximately 2% serving the ornament of the units under investigation. Bartlett's test was applied, whose significance is (P <0.01), which allowed rejecting the null hypothesis that the correlation matrix is ​​equal to the identity matrix, and it is concluded that there is...

Las sales de cromo son reactivos químicos muy utilizados en la industria de curtiembre porque son eficientes para curtir la piel animal, sin embargo, estas sales no se fijan totalmente, por lo que, sus remanentes van a parar a los efluentes, impactando gravemente al medioambiente. El objetivo de este estudio fue remover el cromo (VI) y cromo total de un efluente de curtiembre utilizando electrodiálisis, para ello, se caracterizó una muestra de un efluente de una planta piloto de curtiembre y se preparó una solución sintética en base a ésta, utilizando una sal de cromo para curtiembres de grado industrial, luego, se determinó la corriente límite y se realizó pruebas de electrodiálisis con el 80, 100 y 120% de la corriente límite. Los resultados demostraron que el mayor porcentaje de extracción y el menor consumo de energía eléctrica fue al 80% de la corriente límite.
