What does P340 mean?

What kind of precautionary statement is P340?

Response statements (P3xx) say what to do after an accident, spill, fire or exposure: first-aid steps, rinsing and washing, calling a doctor or a poison centre, choosing the extinguishing medium. They usually open with a situation such as IF IN EYES or IF INHALED.

Which hazards is it used for?

In the CLP Annex IV assignment table used by Chemoris, P340 is not linked directly to a class; it is used as part of a combined statement or at the supplier's choice.

Combined statements containing this code

• P304+P340

Change note

P340 is used in place of the withdrawn P341. When you see the old code in an earlier SDS or label, its current equivalent is P340.

How is P340 read?

The text of P340 is 10 words long. The text is a single instruction without options and is written as it appears in Annex IV.

Where is P340 written in the SDS?

In the SDS, P340 is written in Section 2.2 (label elements) with its code and the text "Remove person to fresh air and keep comfortable for breathing.". Being a response statement, it sits among the response lines. The statement should also agree with the first-aid measures in Section 4.

How does P340 appear on the label?

On the label P340 appears together with its text; under CLP Article 28(3) a label usually carries at most 6 precautionary statements. In the Chemoris selection method, response statements are considered in position 1. 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 P340 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 response candidate is selected.

Which classes and which priority is P340 assigned to?

Related assignment entries: 7 class/category entries, 4 different H statements. Priority split: core (priority 1) in 6 entries and secondary (priority 2) in 1 entries. Of these entries, 3 carry the signal word “Danger”, 2 carry “Warning” and 2 need no signal word. The pictograms that most often accompany it: GHS06 (3) and GHS07 (2).

The class families it appears in most often: Acute Tox. (4), Skin Corr. * (1), Resp. Sens. * (1) and STOT SE (1).

Classes that P340 is assigned to

P340 is not assigned to a class on its own; the combined statements it belongs to (P304+P340) are assigned to these classes:

Where does P340 stand in the response group?

P340 is number 28 of the 82 statements in the P3xx group. The group holds 30 combined and 11 withdrawn statements and 46 single valid statements. Combined statements merge several situations on one line; withdrawn statements are replaced by their current equivalents.

Which SDS section does P340 feed?

Because of its number and its response kind, P340 relates to Section 4 First aid of the SDS; in Section 2.2 it is written with its code and text. Statements in the same number range feed the same section.

Checklist when writing P340

• P340 is a part of the combined statements P304+P340; when a combined statement is selected, P340 is not repeated on the label.
