Information for use of this property

[edit]

1) For Globally Harmonized System of Classification and Labelling of Chemicals (Q899146), please use the relevant regulatory application text: Application of GHS system is dependent on countries regulations and for one chemical sold by one company, you can have different sets of labelling depending on the area where the chemical is sold. So to be able to distinguish between these different labellings, we need to use the regulatory text which is at the origin of these differences. If no mention is done in the MSDS (Material safety data sheet) to which regulatory text the labelling is referring, use the country for which the MSDS is issued. This is usually mentioned in the first page of the MSDS.

2) For Globally Harmonized System of Classification and Labelling of Chemicals (Q899146), please use only labelling data from the labelling section and not data from the classification section. There are some differences in the H-phrases between these two sections.

CIRC Classification of Carcinogens

[edit]

What about those as allowed values ? https://en.wikipedia.org/wiki/List_of_IARC_Group_2A_carcinogens Teolemon (talk) 09:30, 22 July 2018 (UTC)[reply]

@Teolemon: I don't think that this is the right property to do this; the c&l systems that this property was design for are something quite different from IARC classification and we would have to add this data in a bit weird way:
  • safety classification and labelling (P4952) with Qxx that describes IARC document with classification (single monograph?) – this is the way that this property is modelled, first comes the document about classification, then classification or labelling in qualifiers
    • Pxx (new qualifier) with Qyy that describes IARC class
    • source with IARC document again
This is of course possible using P4952, but I see at least two easier ways to add IARC classes:
  • create new property (instead of creating new qualifier for P4952) – this would be the easiest I think, because IARC classes do not have all the problems we have with c&l systems (there would be only one qualifier for IARC class and there is no need to group several qualifiers together like in e.g. GHS or NFPA systems; new property would allow to add qualifiers for IARC classes, e.g. start time (P580), end time (P582), which wouldn't be possible using P4952 etc.)
  • use instance of (P31) with Qxx that decribes IARC class, e.g. compound XXX instance of (P31) IARC group 2A carcinogen
So, it is possible to use P4952 for IARC classification, but it won't be imho the best option. Wostr (talk) 13:46, 22 July 2018 (UTC)[reply]
