Análisis comparativo entre la metodología NTP 330 Y WILLIAM FINE para la gestión de riesgos mecánicos en el área de producción de la Empresa INOX Industrial

Abstract

A comparative analysis between the methodology NTP 330 and William Fine was made in this study to evaluate the existing mechanical risks in the production area and to present a proposal of risk in INOX Industrial Company. The levels of exposure (NE), Probability (NP) and consequence (NC) were considered for the evaluation of mechanical hazards to determine the level of risk (NR), existing in each of the activities involved in the different jobs. The factors of mechanical risks of higher incidence considered as critical situation were the following: In the position of Machines and tools the risks of entrapment by or between objects, projection of fragments or particles and collision with moving objects obtained a NR de 1440 (5.781%) in the NTP 330 and 900 (2.051%) in William Fine; in the position of metallic sheets the risk of indirect electrical contacts obtained a NR of 2400 (9.635%) in the NTP 330 and of 1500 (3.418 %) in William Fine. Making a comparison of the methodologies NTP 330 and William Fine, there is a clear difference in the results of the risk level, due to its rating scale, using the Pareto diagram for the comparison. Found the results of the evaluation, a risk management plan consisting of procedures directed to the different activities of the production area, in order to mitigate or reduce the risk was performed.
