[Protection of medical diagnostic laboratory workers against biohazards].

Medical diagnostic laboratories form a particular occupational environment, in which workers have contact with patients and potentially infectious biological materials thus it should be acknowledged that it poses a significantly increased risk to health of laboratory workers. The risk directly depends on the kind of microbes present in a biological material and natural resistance to infections of individual workers. Therefore, the adopted technical and organizational solutions, properly worked out and obeyed procedures assuring safety work with biological material and microbes and properly trained laboratory staff play an essential role in reducing the risk. The risk of contact with microbes among laboratory workers is higher in Poland than in a number of other countries because hermetic devices for diagnostic analyzes and safety blood sampling systems are not always in use. The most important methods of infectious diseases prevention among laboratory workers are to protect them against direct contact with biological material, to apply vaccinations and to implement proper post-exposure procedures. Appropriate qualifications and habits of workers are of relevance to prevent infections in laboratories. A difficult financial situation of health care in Poland and other economic reasons can significantly increase the risk of infections and endanger health and safety of laboratory workers. It is necessary to develop practical instructions aimed at improving occupational safety to protect this occupational group against harmful effects of biological agents.
