Estudo de conformidade da iluminação de salas elétricas industriais

Abstract

Inadequate lighting in industrial electrical rooms poses a direct risk to worker safety and the operational efficiency of facilities. This paper aims to conduct a compliance study of the lighting system in the electrical room of a Wastewater Treatment Plant (WWTP) operated by a private company, using the ABNT NBR ISO/CIE 8995-1:2013 standard as reference. The methodology adopted a quali-quantitative approach, combining employees’ responses to a visual perception assessment form with the analysis of results from computer-assisted lighting simulation using DIALux evo software. The diagnostic evaluation of the current scenario was carried out through a three-dimensional simulation of the environment and its lighting systems, which revealed three non-conformities: illuminance levels below the normative minimum, uniformity ratio lower than 0.60, and glare values (UGR) above the permissible limit. Workers’ perception corroborated the results of the technical computational studies, indicating dissatisfaction with the quality of the existing lighting, particularly in tasks involving cable and tag identification, which required the use of personal flashlights. The proposed lighting retrofit using Philips Pacific LED Gen5 luminaires (WT490C Series), with stratification of Narrow Beam and Wide Beam optics, demonstrated full compliance with normative requirements. The results highlight the potential for improving working conditions in the studied facility and serve as a reference for diagnostic studies and lighting retrofit projects in similar industrial sanitation installations.
