Regulation (EC) No 1272/2008 (CLP) on the classification, labelling & packaging of chemicals applies to all substances and mixtures placed on the EU market. Through occupational health legislation in many countries, CLP labelling also applies to containers etc in the workplace.
In 2023 new hazard classes were introduced, and in 2024 some classification principles have changed. All suppliers of mixtures, and users of chemicals preparing internal mixtures must (re)classify and label treir mixtures according to CLP.
The training course is aimed at those responsible for mixture classification/workplace labelling. The course leader is Erwin Theelen who has many years of experience with CLP classification in industry and REACH & CLP information. The course objectives are to learn how to classify & label mixtures according to CLP/GHS.
This course is also held in Dutch and Swedish (check our Dutch and Swedish websites).
