What does P370 mean?

What kind of precautionary statement is P370?

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, P370 is not linked directly to a class; it is used as part of a combined statement or at the supplier's choice.

How is P370 read?

Where is P370 written in the SDS?

In the SDS, P370 is written in Section 2.2 (label elements) with its code and the text "In case of fire:". Being a response statement, it sits among the response lines. The statement should also agree with the firefighting measures in Section 5.

How does P370 appear on the label?

On the label P370 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 P370 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 P370 assigned to?

Related assignment entries: 17 class/category entries, 1 different H statements. Priority split: core (priority 1) in 12 entries and secondary (priority 2) in 5 entries. Of these entries, 5 carry the signal word “Danger”, 1 carry “Warning” and 11 need no signal word. The pictograms that most often accompany it: GHS02 (3) and GHS03 (3).

The class families it appears in most often: Flam. Liq. (3), Self-react. * (2), Org. Perox. * (2), Flam. Sol. * (1) and Ox. Gas (1).

Classes that P370 is assigned to

P370 is not assigned to a class on its own; the combined statements it belongs to (P370+P372+P380+P373, P370+P378, P370+P376 and P370+P380+P375) are assigned to these classes:

Where does P370 stand in the response group?

P370 is number 40 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 The group holds 30 combined and 11 withdrawn statements and 46 single valid statements. Combined statements merge several situations on one line; withdrawn statements are replaced by their current equivalents.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 P370 feed?

Because of its number and its response kind, P370 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 P370

• P370 is a part of the combined statements P370+P376, P370+P378, P370+P380, P370+P380+P375; when a combined statement is selected, P370 is not repeated on the label.
• P370 should agree with Section 5; in Section 2.2 it is written with its code and text.
