The diploma thesis deals with explosion protection in the operation of a production hall for processing wood material. The wood operation is focused on the production of children's playgrounds and processes exclusively from black locust wood. The principal document for the thesis was Government Regulation of the Slovak Repbulic no. 393/2006 Coll. on the minimal requirements for ensuring safety and health at work in an explosive atmosphere. Assessment of the risks of explosion in the production hall, the classification of areas with explosive atmospheres into zones was used for 3D modelling. CAD visualization of the 3D modeling program SketchUp was applied to our case conditions. Pursuant to the National Council of the Slovak Republic No. 149/2016 Coll., the locations of equipment according to the category of explosion protection in an explosive atmosphere was proposed. To zone 20 are there of a category 1 D installation, to zone 21 of a category 2 D installation and to zone 22 of a category 3 D installation. To minimize the risk of explosion and mitigate the impact, devices were designed to reduce the dust in the workplace by means of air-conditioning and air humidification equipment. Explosion protection components were designed for the air handling unit. A relief membrane was designed in the part of the cyclone sawdust separator and an anti-explosive chimney was designed on the sawdust extraction air duct. To reduce the remaining risk, organizational measures were also proposed in the thesis. The benefits of 3D modelling are supported by Industry 4.0, which in practice means a faster and more efficient display of complexities in space. The digital three-dimensional projecting of an object in the universal 3D format (AutoCAD DWG file), is an important part in creating a virtual model of explosion protection.
