  • review of DOT special permits and European standard EN 417 for development of gas cartridge requirements for liquefied petroleum gases
  • alignment with the most recent edition of the UN Model Regulations and incorporation of equivalency certificates previously issued by the Transportation of Dangerous Goods Directorate
