ERG 2024 lists UN/NA 2692 (Boron tribromide) under Guide 157, titled “Substances - Toxic and/or Corrosive (Non-Combustible/Water-Sensitive)”.
Material name
2692 on a placard, orange panel or shipping paper
It points to the ERG 2024 entry “Boron tribromide” and to Guide 157. On a numbered orange panel, 2692 is the lower number (how to read an orange panel).
ERG 2024 markings for 2692
2692 is highlighted in green, so ERG 2024 Table 1 (Initial Isolation and Protective Action Distances) has two entries for it: “Boron tribromide (when spilled on land)” and “Boron tribromide (when spilled in water)”. Hazora shows those distances in the app, not on this page. One entry covers a spill on land, the other a spill in water. “When spilled in water” means the material produces large amounts of toxic inhalation hazard (TIH) gases when spilled in water. Table 2 (Water-Reactive Materials Which Produce Toxic Gases) lists the gas produced: HBr (hydrogen bromide). Its guide number 157 has no P.
