What does P283 mean?

What kind of precautionary statement is P283?

Prevention statements (P2xx) describe the measures that stop exposure or an accident before it happens: staying away from heat and ignition sources, wearing personal protective equipment, not breathing vapour or dust, washing hands after work. They are the rules a user applies before starting to work with the product.

Which hazards is it used for?

In the CLP Annex IV assignment table, P283 is assigned to the classes of these hazard statements:

• H271May cause fire or explosion; strong oxidiser.

How many hazard statements is P283 assigned to?

In the CLP Annex IV assignment table, P283 is provided for the classes of 1 H statements in total: 1 physical hazard statement. The lowest-numbered example is H271 and the highest-numbered is H271. Whether a mixture label carries this statement depends on those classes really applying to the mixture.

Where is P283 written in the SDS?

In the SDS, P283 is written in Section 2.2 (label elements) with its code and the text "Wear fire resistant or flame retardant clothing.". Being a prevention statement, it sits among the prevention lines. The statement should also agree with the exposure controls and personal protection in Section 8.

How does P283 appear on the label?

On the label P283 appears together with its text; under CLP Article 28(3) a label usually carries at most 6 precautionary statements. In the Chemoris selection method, prevention statements are considered in position 2. 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 P283 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 prevention candidate is selected.

Which classes and which priority is P283 assigned to?

In the CLP Annex IV assignment table, P283 appears in 2 class/category entries (1 different H statements). Priority split: conditional (priority 3) 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).
