Abstract: Science is one of the significant fields in today’s world. It can be described as the process of perception and recognition of the world, thinking about the nature of knowledge, analysis of knowledge and the ways to access information, construction of new information based on the existing one and making estimations about new events. Laboratories can be regarded as places where experimental studies with various equipment and devices and analyses as well as observations are carried out. In the last century, the number of laboratories increased and nearly all disciplined had their own laboratories. In Turkey almost all middle and high schools have their physics, chemistry and biology laboratories and universities also have highly specialized versions of them. Reforms about the improvement of science education programs in the USA soon affected the science education in Europe and similar educational activities began to be used. Such reforms covered the improvement of the contents of science and mathematics courses. At the same time, the significance of science education was again recognized. It was assumed that laboratories were one of the valid and valuable teaching methods in science education. All these changes in the world also affected in the science education in Turkey. In Turkey, science education program was revised in the years of 1936, 1948, 1968, 1992, 2004 and 2013. According to this arrangement of 2013, the program adopted a holistic approach towards teaching and learning, but it was also accepted that students are responsible for their own learning and active student involvement is needed which requires a constructivist approach. Laboratory work is the basis for and indispensable part of science education and all technological research. Individuals could only use their theoretical knowledge of science in laboratories which makes their learning much more permanent. Therefore, studies at laboratories have some certain risks. It requires that at laboratories there should be a safe working environment since workplace laboratories are classified as dangerous. Therefore, staff should know what to do in emergency situations and be aware of potential dangers. In order to provide a safe environment, certain laboratory rules and techniques as well as necessary equipment should be employed. Following such rules is very significant for the health of staff and their safe.
