+Chemical risks in research laboratories are important to consider due to the numerous chemicals used and their various mixture. Knowing the signification of the hazard pictograms is therefore crucial. Therefore, before starting to work in the laboratories of the LCSB, it is mandatory to follow the Docebo trainging regarding the [Globally Harmonized System for the classification and labeling of chemicals](https://cdn5.dcbstatic.com/dcd/scormapi_v60/launcher_full.html?host=unisupport.docebosaas.com&id_user=13109&id_reference=137&scorm_version=1.2&id_resource=111&id_item=111&idscorm_organization=111&id_package=111&launch_type=fullscreen&id_course=18&player=hydra&autoplay_enabled=0&name=hazard-communication-standard-labels-and-pictograms&return_url=unisupport.docebosaas.com&as_json=1&auth_code=03e78b8ed77301828502c40972fbcadfdb5a249c&context=lms&rtl=false) and to pass the related Quizz.
