See Appendix C here: http://www.ilpi.com/msds/osha/1910_1200_APP_C.html  The tables list the hazard and precautionary statement wording that is required based on each classification.  Harry is correct; HazCom does not reference (and presumably therefore, does not require) the P-numbers.  Your SDS and label should contain, for example, the explicitly written statement, "Keep only in original container" rather than simply "P234", although there is no harm/foul in listing the number in addition to the text.  Honestly, I hate all numbers and since the words associated with numbers could theoretically change in the future and folks might try to memorize them and rely on that; I would avoid them altogether.  Don't even get me started with the 1-4 scale in GHS being opposite to the 0-4 in NFPA and HMIS...

The specific precautionary text requirements are listed at www.ilpi.com/msds/osha/1910_1200_APP_C.html#C.2.4

Note that is permissible to combine precautionary or hazard statements on a *label* under certain circumstances, but this would not be acceptable on an SDS.  See http://www.ilpi.com/msds/osha/I20141110.html  And also www.ilpi.com/msds/osha/1910_1200_APP_C.html#C.2.6 for a discussion of "ranking" statements on labels.

The required P-codes are a direct correlation from the classification of the material.  The correspondence is found in the Purple Book from the UN or in Appendix C of 29CFR1910.1200 "Allocation of Label Elements" although HAZCOM does not list "P-NNN" - it just gives the words and the user needs to make the correlation.

A GHS question for those with more experience than I at writing SDS's:

Are the Precautionary codes associated with a chemical determined on a case by a case basis or are they the same for all chemicals with the same combination of GHS Hazard codes?

Thanks for any information on this.
