Safety of automated industrial valves in operating conditions
Kryštof, Ondřej ; Trávníček, Petr (referee) ; Kotek, Luboš (advisor)
Choosing suitable and safe valve with accessories depends on general specifications for plant. Using valve for on/off, throttling, back-flow prevention, etc., pressure drop is related with Kv value or leakages from piping systems are main factors for properly valve selection. Valve have to resist chemicals and substances that may change the state, temperature and its fluctuation, pressure, corrosion and erosion. This properties determine pressure class, temperature resistance, connection into pipe and sealing material as gland packing, seats, seal between flange etc. This and other specification, listed in this thesis, can help determine suitable type of valve. This thesis deals construction design of valve and accessories as well. The last chapters are focused on calculation of safety valve and selection safe and appropriate control valve with accessories.

Assessment of the operator reliability of the selected machine
Jakl, Tomáš ; Rozehnalová, Jana (referee) ; Kotek, Luboš (advisor)
The master thesis is focused on the reliability of the human factor in the operation of the production machine. In the first part the basic legislative requirements for safety and reliability of work are presented. In the second part, the reliability of the human factor is discussed along with a description of selected methods for assessing the reliability of the human factor. The research section then concludes with a proposed methodology for human factors assessment for the manufacturing process. In the practical part, the proposed methodology is applied to the selected process, which includes risk identification and outputs from the selected methods. The thesis then concludes by recommending preventive measures to eliminate the identified risks.

Safety audit in a plant for the preparation of concrete
Palička, David ; Trávníček, Petr (referee) ; Kotek, Luboš (advisor)
In this thesis I focus on a safety audit in a plant for the preparation of concrete carried out according to Self-Audit Handbook for SMEs. In the first part some examples of accidents in plants for the preparation of concrete in Czech Republic as well as in abroad are stated. In the second part I describe the subject of work injury in Czech Republic and the obligations of employees and employers in accordance with the labour code. The third part deals with the safety management, occupational health and safety management system and briefly covers various types of audits. The next part analyses briefly concrete composition and its production process, the function of plant for the preparation of concrete and safety requirements demanded from the plant for the preparation of concrete in accordance with an appropriate standard. The last part describes the audit itself processed according to Self-Audit Handbook for SMEs at two plants. The aim of this thesis is to process and to evaluate results of two audits that took place at plans for preparation of the concrete and to propose corrective actions and process improvements.
