The thesis is focused on wood dust generated during sanding modified beech. The analysis concerns the characteristics and composition of this dust. The thesis addresses also the danger for human health exposed to the wood dust and its impact on the work environment. The theoretical part is focused on properties and biological effects of airborne dust on the human body as well as the thermal modification of wood. The experimental part was carried out on a test stand to simulate standard sanding. For our experiment three samples were selected, namely a modified beech at 180 °C, 200 °C and a native beech. In order to evaluate the incidence of wood dust, a methodology was designed to determine the representation of individual fractions of wood particles. Very fine particles (particles smaller than 100 micrometres) were subjected to microscopic and probabilistic analysis.

The purpose of this dissertation is to examine the issue of a job position as part of the working environment. It defines basic requirements and is based on the current view of the role of man who is the focal point for creating the working environment in manufacturing industries. The dissertation also deals with closely related occupational health and safety. As it primarily concentrates on the wood processing industry, the assessment of the working environment also examines the issues of fire safety and the ubiquitous wood dust. The purpose of the dissertation is also to create a control system for wood processing companies. The suggested control questionnaire follows its theoretical basis in the presented overview. The practical usability of the questionnaire is subsequently tested in an existing wood processing company. Major faults in areas under review can be identified by the evaluation of the questionnaire survey. On the basis of an evaluation of the current situation, practical measures for every category are suggested in a discussion; the employer can implement the measures to improve occupational health and safety of its employees.
