Regulamentul CLP asigură comunicarea clară a pericolelor pe care le prezintă substanțele chimice către lucrătorii și consumatorii din Uniunea Europeană, prin clasificarea și etichetarea substanțelor chimice. Substances may have impurities and additives that lead to different classifications. This is a non-exhaustive list of substances based on the Article 2 carcinogen and mutagen (CM) definitions and Annex I of Directive 2004/37/EC. These notifications can be provided by manufacturers, importers and downstream users. For readability purpose, only non-confidential use descriptors occurring in more than 5% of total occurrences are displayed. More information about CAS and the CAS registry can be found here. Precautionary statements - describe recommended measures to minimise or prevent adverse effects resulting from exposure to a hazardous product or improper storage or handling of a hazardous product. This section provides links to the list of precautions (precautionary statements) and to the guidance on safe use, if they have been provided in REACH registration dossiers. Please note that it may take a week or two to have everything fully in place, and please be aware in the meantime that the Registration status may be incorrect and the CLP regulatory context may be incompletely shown. The precautionary measures and guidance on safe use are as submitted to ECHA by registrants under the REACH Regulation. 6(6), Reg. The CLP Regulation makes sure that the hazards presented by chemicals are clearly communicated to workers and consumers in the European Union. The substance identifiers displayed in the InfoCard are the best available substance name, EC number, CAS number and/or the molecular and structural formulas. This directive requires employers to ensure proper signage is posted in areas where hazards cannot be avoided or reduced. This section provides an overview of the calculated volume at which the substance is manufactured or imported to the European Economic Area (EU28 + Iceland, Liechtenstein and Norway). Scopul Regulamentului REACH este să îmbunătățească protecția sănătății oamenilor și a mediului față de riscurile pe care le prezintă uneori produsele chimice. This database contains: (1) the list of hazardous substances harmonized for classification and labeling in EU (i.e. Scopul Regulamentului RPB este să îmbunătățească funcționarea pieței produselor biocide din UE, asigurând totodată un nivel ridicat de protecție pentru oameni și mediu. The annexes to this directive provide detailed information about the minimum requirements for all safety and health signs. Other relevant information includes the following: To see the full list of notified classifications and to get more information on impurities and additives relevant to classification please consult the C&L Inventory. In these cases, Infocards may not identify all substances in the group.Therefore it does not represent official and legally–binding information. 2(b)(i) - Hazardous Agents, EU Ecolabels - Restrictions for Hazardous Substances/Mixtures, Protection of Pregnant and Breastfeeding Workers Directive, Annex I+II, Workplace Signs - minimum requirements & signs on containers and pipes, Waste Framework Directive, Annex III - Waste - Hazardous Properties, Carc and Muta Directive, Annex I - Substances, Mixtures & Processes, Fertiliser Regulation- Annex I, E.3 (chelating and complexing agents), Lista substanțelor candidate din articole, Identificarea substanțelor care prezintă motive de îngrijorare deosebită, Activitățile ECHA cu privire la restricționări, Pregătirea unei propuneri de restricționare, Informații despre substanțele restricționate, Noțiuni de bază despre legislația UE privind substanțele chimice, Înlocuirea cu substanțe chimice mai sigure, Clasificarea substanțelor și a amestecurilor, Clasificare și etichetare armonizată (CLH), Denumire chimică alternativă în amestecuri.
