What does P422 mean?

What kind of precautionary statement is P422?

Storage statements (P4xx) set the conditions for keeping the product safely: locked up, in a cool, well-ventilated place or in the original container, protected from sunlight. Warehouse layout and container choice follow from these statements.

Change note

P422 has been withdrawn and the rule file defines no direct replacement for it. When preparing a current label, look at the valid neighbouring storage statements and choose according to the CLP Annex IV assignment table.

How is P422 read?

This statement is a 4-word text. The text is a single instruction without options and is written as it appears in Annex IV.

Where is P422 written in the SDS?

P422 is not written in a current SDS or label; Chemoris automatically turns a selection that falls on this code into its current equivalent. If you see it in an old document, prepare Section 2.2 again.

How does P422 appear on the label?

Because it has been withdrawn, P422 does not appear in a new label draft; the current equivalent is printed on the label instead of this text.

Where does P422 stand in the storage group?

P422 is number 13 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 The group holds 6 combined and 2 withdrawn statements and 12 single valid statements. Combined statements merge several situations on one line; withdrawn statements are replaced by their current equivalents.

Original official wording of P422

P422 appeared in the original CLP text (CELEX 32008R1272) as: “Store contents under …”. If you meet this wording in an old SDS or label, compare it with the current list; Chemoris writes the Turkish template text only for valid codes.

Checklist when writing P422

• The text ends with “…”; the supplier supplies the completion.
• The text is 4 words long; if the label space is narrow, choosing a combined statement can save room.
