A poison centre notification sends information on a hazardous mixture to the appointed bodies, usually poison centres, so they can advise in an emergency.
Art. 45 and Annex VIII CLP
Legal term: appointed bodies responsible for receiving information relating to emergency health response
Explained
Under Article 45 and Annex VIII of the CLP Regulation, importers and downstream users submit information on mixtures classified as hazardous to the bodies that each Member State appoints, in most countries the poison centres. The submission contains the composition and hazard information, together with the UFI that identifies the mixture on its label. When someone calls a poison centre in an emergency, its staff can find the composition through that code. The last transitional deadline for the submissions ended on 1 January 2025. The emergency telephone number belongs in section 1.4 of the safety data sheet. Submissions go through the ECHA portal or through national systems.
