Riesgo percibido por el personal de fiscalización referente a ruido, iluminación, esfuerzo postural y SARS-COV-2 (COVID-19) en los espacios de trabajo de oficina y obra del proyecto primera línea del metro de Quito

Abstract

Objectives 1.- Evaluate the perceived risk of the inspection personnel related to noise, lighting, postural effort and SARS-CoV-2 (COVID-19) that can cause harm to the workers of the inspection of the first line of the Quito metro project, based on the NTP 578 Perceived Risk survey 2.- Verify the effectiveness and efficiency of the occupational risk control systems according to the way in which the inspection workers perceive the risk at the individual level. 3.- Identify biased perceptions and strategies for better communication about risks. 4.- Establish recommendations based on the results obtained. Risk reduction is a common goal for all working personnel, providing safer and healthier working conditions, but for this the concept of “risk” must be understood equally, that is, what is intended to be reduced. The country, allows the need to evaluate the perceived occupational risk of the inspection personnel related to noise, lighting, postural effort and SARS-CoV-2 (COVID-19) that can cause damage to the workers of the inspection of both the work and the central office of the first line of the Quito metro project. It is investigated what is the perception of these personnel in the face of the risks mentioned in their jobs and how informed they are of the consequences of each of them, including the current biological risk that is affecting the population worldwide as it is SARS-CoV-2 (COVID-19), which represent important reasons for risks to the safety and health of workers. It is established to analyze an important sample of the Quito Metro's inspection staff, identify findings to have a reference and evaluate the results in order to obtain data on the effectiveness and efficiency of the dissemination of information to staff on these risks, and based on This will establish the necessary recommendations to provide a better communication of this information to the personnel, with a view to better care before these types of risk factors. Method: It is a descriptive cross-sectional study based on the Questionnaire of the “NTP 578: Perceived risk: an evaluation procedure” [9] made up of ten questions for each risk factor evaluated, questions that are of interest to obtain information appropriate to the present study, carried out anonymously with the prior consent of the respondent, the survey collects information on risk characteristics examined in the research that comprise available scientific knowledge; knowledge by the exposed subject; novelty / familiarity; delayed effect of consequences; voluntariness of the exhibition; controllability / avoidability; lethality of the consequences; fear that it produces; catastrophic potential. The surveys were conducted in January 2021. Results: 60 workers participated, made up of 46 men and 14 women, the men were distributed in 27 men at the work site and 19 at the office, while the women worked 10 at the office and 4 at the work site. It was found that regarding the perceived risk of noise both in the office and on the construction site, there were responses ranging from moderate to high with an average assessment of the risk of accident or illness associated with this factor of 57.6%. Regarding lighting, the perceived risk both in the office and on the job site, a selected level of workers was observed between moderate to high with an average assessment of the risk of accident or illness associated with this factor of 57.3%. Regarding postural effort, most of the responses both in the office and on the job site by the workers were moderate to very high, with a mean assessment of the risk of accident or illness associated with this factor of 63.1%. A particular case was presented by the workers on the risk factor Sars Cov2 (Covid-19) when results were seen between high and very high with an average assessment of the risk of accident or disease associated with this factor of 82.6%.
