Carbon monoxide contamination by wood harvesting and processing

Abstract

Analysis of work environment contamination with carbon oxide by harvesting and wood processing with using of motomanually technology – one-man chainsaw is presented in this paper. This activity belongs to categories of heavy up to very heavy works according to power consumption. Due to psychophysiological load is considered as dynamic work, combined with neuropsychical load by decisions about assortments and safe motion during harvesting and manipulation process.Risk of carbon monoxide (CO) intoxication is inflicted his strong affinity to haemoglobin (Hb). Carbon monoxide produce with haemoglobin karboxyhemoglobin (COHb), whereby disable transmission of oxygen in form oxyhaemoglogin (OHb) from lungs to tissues. Binding of oxide carbon on haemoglobin is approximately two-hundred times stronger as with oxygen.The measures was made with use of multichannel detector of gas and exhalation Drager X-am 7000 (Germany). Data about contamination was recording in one second intervals, with precision on 1 ppm. By harvesting and too by wood processing were realized three independent observation. Data were processing with standard mathematical-statistic methods – sorting and ranking, regression analysis, test of average deuces and evaluation of frequency in classes.
