Workers are exposed to various factors that negatively affect their health at the workplace. It is necessary to determine what harmful factors of the working environment affect workers, and to what extent. The effects can be both long term and short term. This creates a necessity for an additional assessment that would point out what must be improved in the occupational safety system, so that workers are not exposed to harmful factors. Workers are exposed to multiple risk factors that depend on organizational and production processes, as well as the indoor climate. Humanity has always worked on achieving welfare, protecting health, creating a beneficial living environment. As human welfare improves, other key matters pertaining to the existence of humanity, such as health and physical and mental wellness, improve in turn. The times and opportunities change, and one must keep track of the new possibilities provided by science, research and discoveries. Setting stricter requirements for ourselves, we indirectly make the world around us change as well, to improve, take care of the environment and other people. By caring for the environment, we learn and discover how to achieve this more efficiently, with less resources used. If we improve the environment we share, our health will improve, too. As its objectives were accomplished, this research study will show that workers are exposed to harmful risks, and that there is room for improvement in the occupational safety system.
