Hazard analysis of nanoparticles in the workplace environment and design of protective measures against their side effects
Skřehotová, Marcela ; Tesařová, Eva (advisor) ; Mráz, Jaroslav (referee)
The diploma thesis is focused on so called new risks, which currently include the risks associated with various nanomaterials - their production, introduction into practice and use. The paper summarizes the up-to-date knowledge about the characteristics of nanoparticles used and it proposes a procedure to estimate potential consequences of their exposure. The experimental part of the paper is represented by a case study, which introduces the practical application of the proposed procedure aiming at estimated exposure to nanoparticles on the workplace where metal working is executed and resulting occupational risks. The aim of this part of the study was to measure selected parameters of aerosols using a special measuring system working on the principle of laser photometry combined with diffusion charger and detector using Faraday cage. The object of the measurements was to determine the numerical concentration of nanoparticles present in working environment and the representation of size groups of submicron particles. The measurement procedure was designed in accordance with ČSN EN 689, ČSN EN ISO 16000-1 and ČSN ISO 8756 standards and data gained were subsequently interpreted. Afterwards the results were used to design the measures to reduce the risk of health damage when facing chronic inhalation...

Prevention of hazards leading to work injuries on constructions
Drkal, Vítězslav ; Smital, Petr (referee) ; Tichý, Zdeněk (advisor)
The aim of this thesis is to prepare a basic overview of the issue of prevention risks of occupational accidents at construction sites. Prevention is the only effective tool to prevent risks of occupational accidents and occupational diseases (health hazards). The thesis describes the procedures and methods to search, evaluation and risk prevention in the workplace and basic description of the standard ČSN OHSAS 18001. At the same time, there are also compared the results of statistical analysis of occupational accidents for the years 2006 to 2010 in the Czech Republic and selected construction company.

Analysis of safety in transport and servicing of transport facilities for the selected company
ŽAMBERSKÝ, Michal
The thesis, entitled "Analysis of safety in transport and servicing of transport facilities for the selected companies" deals with safety and work-related injuries in transportation and servicing of transport facilities. Occupational injury is caused by a set of several interacting factors. These factors are known as the main source and cause of work-related accidents, which affect the formation of accidents. The most important element in the protection of health and safety is prevention. To evaluate the risks is one of the fundamental principles of the concept of occupational health and safety policy that is enforced in all countries espousing the principles of safe enterprise. The need to protect the health of the individual is already firmly established even in the most basic legal document such as the Constitution of the Czech Republic. The aim of this work is to analyze the factors that are involved in causing accidents at work and on the basis of the analysis, to provide rules and recommendations for farms so that they serve as an aid in the elimination of induced injuries.

Analysis of work safety and work injuries in the field of land transport and material handling.
KAINZ, Aleš
My Diploma thesis describes the issues of safety and labour accidents in an agriculture in particular looking at the handling of agricultural products. The accident at work is due to an aggregation of several interacting factors and the factors are con-sidered as the main source and cause of accidents at work that affect the creation of industrial accidents. The most important element in protecting the health and safety is prevention. An Obligation to assess risk is one of the fundamental principles of the concept of preventive occupational health and safety policy, which is enforced in all countries declaring the principles of safe - company. The basic need to protect the health of individuals is well established in the Constitution of the Czech Republic. The primary objective of this work is based on an analysis of factors involved in causing accidents at work and on the basis of the analysis, rules and recommenda-tions for the farms so that they serve as a support in the elimination of such acci-dents.
