Evaluación in situ del riesgo toxicológico por inhalación de Butanol, Ciclohexanona y Metilacetato de los trabajadores en el proceso de acabado de productos de un taller de maderas

Abstract

An assessment study of volatile organic compounds (VOC’s) generated in the process of a company's wood products finishing workshop was conducted using the Quality Standard for environments ISO 171330. Cyclohexanone (C6OH10), Methylacetate (C6H12O3) and Butanol (C4H10O) using the UNE 689 Chemical Risk Assessment Standard considering several 983 tests under environmental conditions of: temperature (T) 21 Celsius degrees: 50 percent relative humidity (HR) and atmospheric pressure (Pa) of 1 atm. For concentration measurement, direct measurement equipment with iBRiD MX6 photoionization sensor that meets NIOSH 1300 standards was used. As a result, the most likely value for; cyclohexanone was 21,00 ppm, for methylacetate: 268,74 ppm and for butanol: 311,65 ppm. Exposure rates were: 1.00, 1.34 and 15.58 respectively; determining a value of the total exposure rate of 17.92 that exceeds 1692 percent the Recommended Environmental Limit Value (VLA). To complete the study, an attenuation system was determined by determining a total ventilation flow rate of 18.697 m3 for h; the speed of generation (G) was 0.25 m3 for h, 0.11 m3 for h and 0.14 m3 for h respectively; the total evaporation rate (Et) calculated is 1.9 l for h and the safety factor (K): 1; for this purpose the parameters required by the Institute for Occupational Safety and Hygiene (INSHT) were used.
