The number of pages in an SDS may vary and depends on the amount of information that exists for each particular substance. In Australia SDS should follow either the format outlined by the GHS (Globally Harmonised System) or the National Code of Practice for the Preparation of Material Safety Data Sheets, 2nd Edition (NOHSC2011-2003), which stipulate a 16-section format:

Section 10 – Stability and reactivity
Section 11 – Toxicological information
Section 12 – Ecological information
