Definition

Precautionary Statements (P-Statements) are part of the Globally Harmonized System of Classification and Labeling of Chemicals (GHS). Precautionary statements provide standardized wording and/or pictograms to describe recommended measures that should be taken to minimize or prevent adverse effects resulting from exposures to a hazardous product, or improper storage, handling, or disposal of a hazardous product.

The GHS also has Hazard Statements which provide standardized hazard wordings. You will usually find both P- and H-statements on a label or Safety Data Sheet.

In the European Union, P-statements have replaced Safety phrases (S-phrases) with the adoption of the GHS under Regulation (EC) No 1272/2008 (20 MB PDF file).

Additional Info

Precautionary statements are assigned a unique numerical code which can be used as a handy reference when translating labels and SDS's written in other languages. The codes are not a substitute for writing out the entire text of the statement.

The codes have the form Pnxx where P stands for "Precautionary Statement", xx is a sequential numbering scheme, and the value of n refers to:

1. general precautionary statements
2. prevention precautionary statements
3. response precautionary statements
4. storage precautionary statements
5. disposal precautionary statements

Thus, a Safety Data Sheet or label might bear a statement such as "Pressurized container; Do not pierce or burn, even after use (P251)". P indicates a Precautionary Statement, the 2 indicates it is a prevention precautionary statement, and 51 is part of the numbering scheme.

SDS Relevance

The US, Europe, and numerous other countries have adopted the Globally Harmonized System, which requires manufacturers and importers of potentially hazardous chemicals to perform a hazard classification of the materials they sell or import.

Encourage safety on the job with electronic safety scoreboards from Safety Emporium.

If that process, required under Paragraph (d) of 29 CFR 1910.1200, the OSHA Hazard Communication Standard (HCS 2024), indicates a hazard, the applicable H-statements and precautionary statements must be provided on the Safety Data Sheet (see paragraph (g)) and the label (see paragraph (f)).

Per Appendix D of HCS 2024, the H- and P-statements will appear in Section 2 of the SDS. Note: If a sheet was issued before the HCS 2012 took full effect the (M)SDS may not only be in a different format, it may not contain these statements. If you have a sheet like this in your collection you should attempt to find a current version. Remember that P-statements phrases only indicate the safety precautions that you need to follow when using the material, not the explicit hazards of the material. For hazards information see the Hazard Statements entry.

This section discusses SDS relevance, but precautionary statements are equally important on labels. Under paragraph C.2.4 of Appendix C of HCS 2024, precautionary statements may be combined or consolidated to save space and improve readability, minor textual variations are permitted when they do not dilute the safety advice, and overlapping statements may be prioritized so the most stringent or most urgent response is communicated.

That flexibility may help explain why the HCS does not use or require GHS P- and H-codes. These codes are useful reference identifiers and may accompany the statements, but they do not substitute for the required statement text.

A good SDS author will include both the statement(s) and their corresponding code(s), e.g. "Pressurized container: Do not pierce or burn, even after use. (P251)" so that the information text is completely intelligible to a worker who has never heard of P251, while the code provides tremendous value to an SDS editor, EHS professional, database, translator, or knowledgeable reader who can trace that requirement back to both the GHS and HCS.
