The system acts as a complement to the UN numbered system of regulated hazardous material transport.

To classify a flammable gas, data on its flammability, on its ability to ignite in air and on its chemical instability are required. In case of categorisation in Category 1B, data on its lower flammability limit or its fundamental burning velocity are required. The classification is according to decision logic 2.2.
