LABORATORY AND WORKPLACE SAFETY
Learning outcomes of the course unit
to provide the basis for the evaluation of the relationship between reactivity and risks associated with the holding and manipulation of chemicals, with emphasis on organic chemicals. Knowledge of the good laboratory procedures for the full personal and workers respect of safety criteria, as well as of the environment. Knowledge of the legislative frame associated with the development of chemical achievements. Students should thus gain a basic knowledge for a correct approach to the manipulation of chemicals, within the frame of the reference legislation and comprehend the language and methods on safety issues.
