Riesgo toxicológico del monóxido de carbono en el ambiente laboral de la Empresa Consorcio revisión vehicular Danton-Cuenca

Abstract

In this work the toxicological risk for workers of the company CONSORCIO REVISION VEHICULAR DANTON due to CO from vehicles in the workplace was established since the levels of carboxyhemoglobin (% COHb) start and end of day with the reference values compared to Cuenca, CO profiles defined in the emission during the workday and its correlation with% COHb final, personal characteristics were analyzed and safety of workers thus establishing preventive measures. For the determination of % COHb the microdiffusionFeldestein - Klejdenshop and spectrophotometry method was used at the beginning and end of the workday in three monitoring; CEA in the University of Cuenca conducted monitoring CO in air for 9 hours in the work in the same days of monitoring COHb % by survey and personal safety of each worker characteristics was assessed with reference data of CO EPA / IRIS and 95 % percentile values workplace air CO both CRV. Toxicological risk was calculated. The results had significant differences between% COHb start and end p ˂ 0.05, in the COHb % final, there were significant differences among personnel exposed and not exposed; the occupational air monitoring CO Mayancela exceeded the limits, CP = 1, FE = 0.86, Capulispamba values were below the limits, CP = 0.73, FE=1.3; It has been recommended frequent use of protection mechanisms, establish ventilation and air renewal of labor in the two CRV.
