What does P371 mean?

What kind of precautionary statement is P371?

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, P371 is not linked directly to a class; it is used as part of a combined statement or at the supplier's choice.

How is P371 read?

This statement is a 8-word text. The text only names the situation "In case of major fire and large quantities"; the instruction itself is completed in the codes that combine with this statement (see the combined statements below).

Where is P371 written in the SDS?

If P371 is on the list of precautionary statements in Section 2.2, it is printed with its code and the text "In case of major fire and large quantities:". The statement should also agree with the firefighting measures in Section 5.

How does P371 appear on the label?

P371 shows up on a label only if it is selected: the candidates from Annex IV are reduced to at most 6 under Article 28(3). 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 P371 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 P371 assigned to?

Related assignment entries: 2 class/category entries, 1 different H statements. Priority split: secondary (priority 2) in 2 entries. Of these entries, 2 carry the signal word “Danger”, 0 carry “Warning” and 0 need no signal word. The pictograms that most often accompany it: GHS03 (2).

The class families it appears in most often: Ox. Liq. (1) and Ox. Sol. (1).

Classes that P371 is assigned to

P371 is not assigned to a class on its own; the combined statements it belongs to (P371+P380+P375) are assigned to these classes:

Where does P371 stand in the response group?

P371 is number 41 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 The group holds 30 combined and 11 withdrawn statements and 46 single valid statements. Combined statements merge several situations on one line; withdrawn statements are replaced by their current equivalents.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 P371 feed?

Because of its number and its response kind, P371 relates to Section 5 Firefighting 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 P371

• P371 is a part of the combined statements P371+P380+P375; when a combined statement is selected, P371 is not repeated on the label.
