    $a Formation and presence of dust in the timber premises is part of the technology. Dust is generated as a byproduct based on the method of machining. The paper deals with granulometric analysis of selected samples of wood dust sessile oak (Quercus petraea Liebl.) and from deciduous multiple-pore wood there was chosen European beech (Fagus sylvatica L.) and alder (Alnus glutinosa L.) and the mixture taken directly from timber production of grinders SCM SANDYA 300RCS) for the purpose of selecting the percentages of the various fractions (0.032; 0.063; 00:08; 0.125; 0.250; 0.5; 1; 2 mm) of samples of wood dust. Wood dust samples were made using a hand orbital sander BOSCH PSS 200AC and sizing on the automatic mesh vibratory sieve machine Retsch AS 200 control. The most frequent percentages of dust particles (between 50-79 %) in all samples of wood dust there were fractions of 32 and less than 32 mu m (bottom). The most abundant percentage creates conditions of the risk of inhaling and respirable components contained in the fraction over 32 mu m and the potential of formation of a dust-air explosive mixture. Comparison of results granulomertic fractions contribution of wood sanding dust typically processed wood in the furniture industry (beech, oak, spruce, fir, and alder) was significantly confirmed of the particle size.
