What does P310 mean?

What kind of precautionary statement is P310?

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, P310 is assigned to the classes of these hazard statements:

• H310Fatal in contact with skin.
• H314Causes severe skin burns and eye damage.
• H318Causes serious eye damage.
• H330Fatal if inhaled.

Combined statements containing this code

• P301+P310

In the CLP Annex IV assignment table, P310 is provided for the classes of 4 H statements in total: 4 health hazard statements. The lowest-numbered example is H310 and the highest-numbered is H330. Whether a mixture label carries this statement depends on those classes really applying to the mixture.

Where is P310 written in the SDS?

In the SDS, P310 is written in Section 2.2 (label elements) with its code and the text "Immediately call a POISON CENTER/doctor/…". 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 P310 appear on the label?

On the label P310 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 P310 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 P310 assigned to?

In the CLP Annex IV assignment table, P310 appears in 6 class/category entries (3 different H statements). Priority split: core (priority 1) in 6 entries. Of these entries, 5 carry the signal word “Danger”, 0 carry “Warning” and 1 need no signal word. The pictograms that most often accompany it: GHS06 (4) and GHS05 (1).

The class families it appears in most often: Acute Tox. (4), Skin Corr. * (1) and Eye Dam. (1).
