How many hazard statements is P405 assigned to?

In the CLP Annex IV assignment table, P405 is provided for the classes of 27 H statements in total: 27 health hazard statements. The lowest-numbered example is H300 and the highest-numbered is H371. Whether a mixture label carries this statement depends on those classes really applying to the mixture.

The statements closest in number to P405 in the storage group:

  • P402Store in a dry place.
  • P403Store in a well-ventilated place.
  • P404Store in a closed container.
  • P406Store in a corrosion-resistant/… container with a resistant inner liner.

How is P405 read?

The length of P405 is 3 words. The text is a single instruction without options and is written as it appears in Annex IV.

Where is P405 written in the SDS?

When you prepare an SDS, P405 goes into Section 2.2; options in the text (slashes or square brackets) are narrowed down to the product before it is written. The statement should also agree with the safe storage conditions in Section 7.2.

How does P405 appear on the label?

The classes and the use of the product decide whether it reaches the label; not all candidates are written, at most 6 statements remain. In the Chemoris selection method, storage statements are considered in position 3. If the core statements exceed 6, Article 28(3) allows up to 8; when a combined statement is chosen, its individual parts are not repeated on the label. As P405 is on the list of precautionary statements of Annex IV, it can be used in current labels and SDSs; Chemoris writes it into the document only when the relevant storage candidate is selected.

Which classes and which priority is P405 assigned to?

In the CLP Annex IV assignment table, P405 appears in 17 class/category entries (7 different H statements). Priority split: core (priority 1) in 9 entries and secondary (priority 2) in 8 entries. Of these entries, 11 carry the signal word “Danger”, 2 carry “Warning” and 4 need no signal word. The pictograms that most often accompany it: GHS06 (9), GHS08 (3) and GHS07 (1).

The class families it appears in most often: Acute Tox. (9), STOT SE (3), Skin Corr. * (1), Muta. * (1) and Carc. * (1).

P405 is number 5 of the 19 statements in the P4xx group. The group holds 6 combined and 2 withdrawn statements and 12 single valid statements. Combined statements merge several situations on one line; withdrawn statements are replaced by their current equivalents.

Which SDS section does P405 feed?

Checklist when writing P405

  • P405 should agree with Section 7; in Section 2.2 it is written with its code and text.
