ERG 2024 lists UN/NA 1067 (Dinitrogen tetroxide) under Guide 124, titled “Gases - Toxic and/or Corrosive - Oxidizing”.
Material name
1067 on a placard, orange panel or shipping paper
It can stand for either of two ERG 2024 entries: “Dinitrogen tetroxide” and “Nitrogen dioxide”. Both use Guide 124, so the number alone is enough to find the guide. On a numbered orange panel, 1067 is the lower number (how to read an orange panel).
ERG 2024 markings for 1067
1067 is highlighted in green, so ERG 2024 Table 1 (Initial Isolation and Protective Action Distances) has an entry for it: “Dinitrogen tetroxide”. Hazora shows those distances in the app, not on this page. Its guide number 124 has no P.
