Análisis y evaluación de riesgos de laborales del Proyecto de Soterramiento de Cables (Primarios 8A y 8B) de la EEQ, San Blas

Abstract

Abstract: This research project was prompted by the constant exposure of workers during the underground cable burial undertaken in the Proyecto de Construcción de los Primarios 8A y 8B de la Empresa Eléctrica Quito . In Ecuador, scarce local studies and lax preventive routines magnify personnel vulnerability. The study aimed to conduct a comprehensive risk assessment to build an evidence base for control measures capable of transforming the jobsite into a safer, more humane environment. The NTP 330 matrix ranked safety risks systematically, while the REBA survey quantified postural stress among laborers, bricklayers and foremen. Findings flagged trench collapses and run-overs as Intolerable , mandating immediate safeguards, and disclosed Medium musculoskeletal loads across key trades. The resulting roadmap couples engineered barricades, proximity alarms, supervisory lock-outs and postural-hygiene coaching, embedding worker dignity at the core of infrastructure advancemen.
