Abstract
El presente trabajo aplicó la metodología bowtie a los riesgos críticos pertenecientes al área de conservación de carreteras de la empresa Autopista del Norte con el fin de reducir el nivel de criticidad de estos; y así mismo disminuir la severidad y/o probabilidad de perdidas en un accidente de trabajo con daños a los materiales, equipos o personas.
De la evaluación inicial de riesgos se identificaron cinco riesgos críticos a los cuales se les aplicó la metodología bowtie, donde se identificaron los peligros, eventos top, causas o amenazas, consecuencias, barreras o controles preventivos, barreras o controles mitigadores, factores de degradación, barreras o dominio de agente de degradación en obstáculo provisorio o atenuantes. Luego de aplicada la metodología se reevaluaron los riesgos iniciales disminuyendo el nivel de criticidad de los mismos.
Luego de aplicada la metodología bowtie a los cinco riesgos críticos, se lograron identificar treinta y un controles adicionales entre preventivos, mitigadores y de degradación; que ingresados a la reevaluación de riesgos disminuyó la severidad y probabilidad obteniendo un nivel final de riesgo de categoría baja.
La metodología bowtie se complementó con la evaluación inicial de la matriz de riesgos haciendo que las probabilidades y severidades disminuyeran desde un nivel de riesgo alto a un nivel de riesgo bajo. Con esto se obtuvo que la gestión de riesgos aplicando la metodología bowtie disminuye la ocurrencia de un accidente o hace que las pérdidas sean menores si este acontece.
This work applied the bowtie methodology to the critical risks belonging to the highway conservation area of the Autopista del Norte company in order to reduce their level of criticality; and also reduce the severity and/or probability of losses in a work accident with damage to materials, equipment or people. From the initial risk assessment, five critical risks were identified to which the bowtie methodology was applied, where the hazards, top events, causes or threats, consequences, barriers or preventive controls, barriers or mitigating controls, degradation factors, barriers or domain of degradation agent in temporary or mitigating obstacle. After applying the methodology, the initial risks were re-evaluated, reducing their level of criticality. After applying the bowtie methodology to the five critical risks, thirty-one additional controls were identified, including preventive, mitigating and degradation controls; who entered the risk reassessment, the severity and probability decreased, obtaining a final risk level of low category. The bowtie methodology was complemented with the initial evaluation of the risk matrix by decreasing the probabilities and severities from a high risk level to a low risk level. With this, it is obtained that risk management applying the bowtie methodology reduces the occurrence of an accident or makes the losses smaller if it occurs.
