What does P342 mean?

What kind of precautionary statement is P342?

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, P342 is not linked directly to a class; it is used as part of a combined statement or at the supplier's choice.

How is P342 read?

The length of P342 is 4 words. The text only names the situation "If experiencing respiratory symptoms"; the instruction itself is completed in the codes that combine with this statement (see the combined statements below).

Where is P342 written in the SDS?

When you prepare an SDS, P342 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 first-aid measures in Section 4.

How does P342 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, 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 P342 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 P342 assigned to?

Related assignment entries: 1 class/category entries, 1 different H statements. Priority split: core (priority 1) in 1 entries. Of these entries, 0 carry the signal word “Danger”, 0 carry “Warning” and 1 need no signal word.

The class families it appears in most often: Resp. Sens. * (1).

Classes that P342 is assigned to

P342 is not assigned to a class on its own; the combined statements it belongs to (P342+P311) are assigned to these classes:

Where does P342 stand in the response group?

P342 is number 30 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 The group holds 30 combined and 11 withdrawn statements and 46 single valid statements. Combined statements merge several situations on one line; withdrawn statements are replaced by their current equivalents.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 P342 feed?

Because of its number and its response kind, P342 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.
