Implementación de procedimientos de bloqueo y etiquetado (LOTO) en la zona 300, para el control de energías peligrosas en la Empresa Unión Cementera Nacional UCEM S.A.

Abstract

The objective of this research was the implementation of LOTO lockout and tagout procedures for the control of hazardous energies in zone 300, in the company Unión Cementera Nacional UCEM S.A. First, a diagnosis of zone 300 was conducted, in which very important data was obtained, the information collected was through a survey, where a sample of 57 workers were evaluated, which provides 95% reliability, on the knowledge of safety procedures, what determined that the personnel have no knowledge of these procedures, as a consequence of suffering accidents in maintenance activities. Subsequently, LOTO methodology was implemented, and it is designed to provide lockout and tagout procedures, which are used to ensure that the equipment is turned off and inoperable until maintenance or repair work is completed, thus mitigating the risks present in each operational and maintenance activity, obtaining a decrease from high risks to low risks, either by acting or blocking all sources of hazardous energy. It was concluded that the LOTO blocking and labeling procedure routines control the risk factors identified in each machine and equipment in the area during the execution of technical operations and maintenance, acting directly on the source generating the risk. Based on this, the LOTO lockout and tagout procedures were implemented in zone 300 of Unión Cementera Nacional S.A. It is recommended to improve or replace the procedures every year to avoid problems with the operators.
