    The main objective of this research work is the development of the ergonomic study of Lighting and Noise levels in the company CNT E.P. matrix Ambato Sur; this due to the relocation of jobs as a result of the appearance of the global pandemic caused by COVID 19 and the renovation of the electric generator that supplies electricity in case of emergency to the main building; The research modality used is of an applied type and includes the measurements in the 62 fixed posts, in addition to the 4 common areas and in the generator room; different methodologies are used in the study; To identify the initial situation of the company, Check Lists are prepared for the collection of information, based on the “Questionnaire for Evaluation and Conditioning of Lighting in Workplaces, for the lighting section; and for noise the: “Questionnaire: Noise: Ergonomic Evaluation and Conditioning”; obtaining that 12 jobs were relocated, in which no previous measurements have been made; For the different data collections, the methodology suggested by NTP 211 is used for measurements of lighting in workplaces, and the methodology suggested by the Superintendence of Occupational Risks, for measurements in common areas; and for the noise section, the methodology of NTP 270 is taken as a reference; With the help of a Super-Scientific 850007 luxmeter and a Cirrus CR:C162 sound level meter, the measurements are taken; the values are compared with the standard present in Decree 2393; giving as a result that 17.91% of the workstations present risk: 9 workstations are above 800 luxes and 3 workstations are below 300 luxes; for the noise part, no values are found that exceed the maximum levels; With the help of the hierarchical structure present in ISO 45001 and based on the document "Assessment and conditioning of lighting in Workplaces", the analysis of the positions that present inconveniences is carried out and solutions are proposed to mitigate the risk; minimal adjustments are made in the workstations; thus eliminating the irrigation present in said posts; this being a study of great contribution to the ergonomics of the company.
