Classification

This field shows the classification of the substance. Thereby various sources are used.

The harmonized classification and labeling of the substance (defined by ECHA under the CLP Regulation, Annex VI) will always be displayed. See below the list of hazard classes and distinctive hazard categories.
Carcinogens: The classification of carcinogens across multiple sources. More information: Hazard Banding of carcinogenicity Classifications.
Group classification: for metals in particular, classifications are determined as 'Metal X and compounds'. Only the CAS number of the elemental metal X is mentioned. The X-compounds are not mentioned in more detail (no name or CAS number). In DOHSBase Compare, the individual X-compounds from the supporting advisory reports (DECOS, SCOEL, IARC, AGS) are linked to the classification of the metal. Furthermore, an algorithm linked the classification of the metal with the individual X-compounds. As a result, all known X-compounds have been given a classification.
DOHSBase evaluation: For substances without a harmonized classification DOHSBase BV evaluates the notified classifications by experienced occupational hygienists and toxicologists (as a consultancy at the request of customers). Herewith a scheme is used for this. The result is a classification, indicated by the attribute "DOHSBase evaluation: .." and the date (e.g. '(2015-12-24)') on which this assessment was performed. The evaluation of the notified classification by DOHSBase is a suggestion for the user. No rights can be derived from it.
Annex III REACH: ECHA has made an inventory of substances that are likely to meet the criteria of Annex III to the REACH Regulation. The inventory is intended to assist registrants to check if the limited minimum information requirements are applicable or whether all information required in Annex VII should be submitted. The information from this inventory is also included in this field, with the prefix "Annex III listing".
Australian GHS: Substances that do not have a harmonized classification in the CLP may have a classification in the Australian version of GHS. The classification in the Hazardous Chemicals Information System of Safe Work Australia is then included in this field as text (eg "Causes serious eye irritation. Causes skin irritation. Cause respiratory irritation"), preceded by " Austrialia GHS: .. ". The corresponding codes of the H-phrases are also displayed in the GHS Hazard Statement Code (s) field {linkID = 50092}. Additional information has also been included from (AICIS; Australian Industrial Chemicals Introduction Scheme). This is the Australian equivalent of REACH. The 'tiered human health assessment' databases in particular are included in the absence of REACH or CLP information.
Non-evaluated classification: For substances without a harmonized classification or an evaluation by DOHSBase of the notified classification, specific classifications and H-sentences have been identified in the notified information using an algorithm. This concerns CMR properties, damage to organs, acute health hazards, etc. If a substance has at least 1 of these classifications, this is stated in the "Properties" tab under "Hazard statement" in the "Classification" field with the following text " > = 1 EU-CLP, aggregated, non-evaluated, classification ### ". The position of ### then shows the specific properties, for example "STOT RE H373" or "Lact. H363 & Skin Sens. 1 / 1AB". The corresponding H-phrases are presented in the "GHS Hazard Statement Code (s)" field. By "non-evaluated" we mean that we have not carried out an evaluation of the value of the result. It is possible that the algorithm gives information from 1 notifier, but can also be from many notifiers. If you want to be sure, make your own assessment of the information of all notifiers, or ask for DOHSBase to perform this evaluation.

According to CLP dangerous substances or mixtures shall be classified in categories of one or more hazard classes. The following CLP classifications are shown in DOHSBase. The corresponding H-statement codes are also given, these are also displayed in the field [GHS Hazard Statement Codes](../03_substance_properties/GHS Hazard Statement Codes.md).
