This training is intended for those who need to widen their general knowledge of chemical safety. It could be used by persons • who handle chemicals in their work; • who have to decide on measures where chemical information is needed, such as workers' safety representatives needing physical and chemical information on a specific substance, or a factory inspector looking for Occupational Exposure Limits; and • who guide and educate others in the handling and use of chemicals. This training material consists of eight independent modules which cover the different areas of managing chemical hazards. It contains material usable in handouts, demonstrations and exercises, as well as slides, colour transparencies and diskettes containing text files and databases. The text is designed to be used as background material for training sessions and discussions.
