SDS Relevance

Many of DOT's regulations parallel or further define OSHA regulations regarding health and safety in the workplace. A terrific summary of these is available from DOT on their web page titled How to Comply With Federal Hazardous Materials Regulations. This document is a must-read for anyone who is shipping or transporting hazardous materials.

DOT's Hazardous Materials Regulations apply to the following (see: 49 CFR 171.1(a)):

The 2012 revision of 29 CFR 1910.1200, the OSHA Hazard Communication Standard (HCS) was designed to align US SDS regulations with the Globally Harmonized Standard (GHS) system. As a result, Safety Data Sheets must follow a standard 16-section format, of which section 14 covers transport information. However, because OSHA does not have jurisdiction over US transport regulations, this section is non-mandatory in the US (but may apply in other countries). If present, Section 14 will contain the following information:

  1. UN number
  2. UN proper shipping name
  3. Transport hazard class(es)
  4. Packing group, if applicable;
  5. Environmental hazards (e.g., Marine pollutant (Yes/No))
  6. Transport in bulk (according to Annex II of MARPOL 73/78 and the IBC Code)
  7. Special precautions which a user needs to be aware of, or needs to comply with, in connection with transport or conveyance either within or outside their premises.
