GHS REFERENCE / P-CODES

GHS precautionary statements (P-codes)

The "what to do about it" half of every SDS and label. GHS Annex 3 groups them by their first digit — general, prevention, response, storage, disposal — and that is exactly how our engine prints them in SDS Section 2 and on container labels. Each code links to the hazard statements that call for it.

When SDS HQ authors an SDS or a container label, it assigns the hazard statements, signal word, pictograms, and precautionary statements from these same tables — automatically, with the calculation shown.
