Wood-processing industry in South Bohemia - variety of health risk assessment
SEDLÁČKOVÁ, Lucie
In my diploma thesis I deal with the issue of the working environment in the woodworking industry and the diversity of the associated risks, such as noise, dust, vibrations, chemicals, physical load and working position. This issue is current due to the rise of custom joinery. Demand also rises for the quality hard wood and its products, so part of my work deals with this issue as well. I find problematic the variability of the work environment related to measurable environmental parameters. The theoretical part will be based on literature and legislation related to this issue. The areas related to wood-processing operations will be detailed. This issue is handled mainly in relation to the hygiene of work and occupational medicine. Therefore the legislation and terminology, on which the practical part is based, devote a considerable part of the theoretical part. Three companies operating in Southern Bohemia were deliberately selected for research. The practical part is based on the measurement protocols of the individual working environment factors. I obtained the results using secondary analysis of data from measurement protocols of individual factors, professional literature, decrees, government regulations and laws. Two objectives and three research questions have been set for research. Objective 1: The work will identify risk factors for the work of woodworkers. Objective 2: The work will evaluate proposals for employers' precautions to protect the health of workers in individual woodworking plants. V1: Are there significant differences in the occurrence of risk factors in woodworking with regard to the way wood and its products are processed? V2: Are there significant differences in the precautions for the health protection in wood production according to the way of processing of wood and its products? V3: How does hardwood dust affect woodworking technology and health protection precautions? The first objective was chosen for the factual description of the working environment of individual companies, as the individual operations differ significantly from the occurring risk factors and their risk. The second objective was chosen with regard to the importance of properly chosen health protection precautions. Failure to comply with the employer's obligations linked to the protection of workers' health may result in serious and permanent damage to health. The importance of appropriately chosen precautions results from the final part of my work.

Hygiene Factors Issues of Noise, Dust and Vibrations in the Workplace Grinding Castings
STODOLOVSKÁ, Květa
My diploma work is focusing on the health problems of selected factors in the working enviroment of grinding the metal castings. There are high-risk factors, which are harmful to worker´s health, especially physical stress, noise, dust and vibrations, which are passed on hands. The employer is under the obligation to take precautions to carry on worker´s health, in consideration of exceed the health limits. The aim of this diploma work was setting the efficiency of precautions to health protection in work enviroment. The situation had been monitoring in a company in the South Bohemia over ten years. There were used results of factor´s precautions (noise, dust, vibrations) in work enviroment, where workers grind the metal castings by hand grinders. The monitoring ensemble was created by employess in a company, which makes the metal castings by hand grinders in its work enviroment. To data collecting were used the following methods: non-aligned observation, conversation with the chief of the company, studying of positive law and technical literature incl. test codes of the health institute (department Ceske Budejovice). The data of the test codes were processed by the secundary analysis and summarized to tables and graphs. Within qualitative analysis I determinated four research questions, which were answered gradually in my work: 1)Which precautions are carry out by employers to particular factors of employee´s health protection? 2)What is the factor´ s efficiency? 3)What impact do the precautions have on results of factor´s measuring? 4)Which precautions can I recommend on the grounds of the evalutation of the work enviroment? Both means of collective and individual protection belong to the precautions of worker´s health protection today. The technical, technologiacal and organisational precautions are included to collective protections. The individual precautions are focusing especially on employees and offer the substitute solutions. All precautions are specific to individual factors. I found out, that all precautions, which are used by the employers in work enviroment of metal casting, are effective. Especially we can talk about the precautions to protection of employee´s health against excessive dust (instalation of air ventilation with strong effect), which caused the exceed of dust concetration in work enviroment of grinding. Finally I can say, that this branch of metal casting has been connecting with certain high-risk factors all the time. Although all the protective precautions has been realized, the health limits given for noise, vibrations passed on hands and dust are still exceed. For this reason it´s very important to regularly inform the workers of high-risk factors, which they could meet in their work enviroment of cast grinding.
