ERG 2024 lists UN/NA 1079 (Sulfur dioxide) under Guide 125, titled “Gases - Toxic and/or Corrosive”.
Material name
1079 on a placard, orange panel or shipping paper
It can stand for either of two ERG 2024 entries: “Sulfur dioxide” and “Sulphur dioxide”. Both use Guide 125, so the number alone is enough to find the guide. On a numbered orange panel, 1079 is the lower number (how to read an orange panel).
ERG 2024 markings for 1079
1079 is highlighted in green, so ERG 2024 Table 1 (Initial Isolation and Protective Action Distances) has an entry for it: “Sulfur dioxide”. Hazora shows those distances in the app, not on this page. 1079 is also one of the six common TIH gases in Table 3, which covers large spills by container type. Its guide number 125 has no P.
