- ERG 2024
ERG 2024 lists UN/NA 1859 (Silicon tetrafluoride) under Guide 125, titled “Gases - Toxic and/or Corrosive”.
Material name
1859 on a placard, orange panel or shipping paper
It can stand for either of two ERG 2024 entries: “Silicon tetrafluoride” and “Silicon tetrafluoride, compressed”. Both use Guide 125, so the number alone is enough to find the guide. On a numbered orange panel, 1859 is the lower number (how to read an orange panel).
ERG 2024 markings for 1859
1859 is highlighted in green, so ERG 2024 Table 1 (Initial Isolation and Protective Action Distances) has an entry for it: “Silicon tetrafluoride”. Hazora shows those distances in the app, not on this page. Its guide number 125 has no P.
