CLPplay is a tool that can be used to put into practice knowledge on European CLP Regulation 1272/2008. The CLPplay video game is an interactive, fun and informative application that allows users of chemical products in the work environment to learn, assimilate and remember easily the new classification, labelling and packaging (CLP) regulations. The chemical labelling system was modified in 2010 for substances, and in 2015 mixtures were also added, thereby fully replacing the previous labels. CLPplay assists in the training of workers in the new labelling system. The objective is to help workers to memorise the new H pictograms and statements on chemical product labels, associating them with their meaning. It is intended for management and workers in companies that handle chemicals.
