ERG 2024 lists UN/NA 1746 (Bromine trifluoride) under Guide 144, titled “Oxidizers (Water-Reactive)”.
Material name
1746 on a placard, orange panel or shipping paper
It points to the ERG 2024 entry “Bromine trifluoride” and to Guide 144. On a numbered orange panel, 1746 is the lower number (how to read an orange panel).
ERG 2024 markings for 1746
1746 is highlighted in green, so ERG 2024 Table 1 (Initial Isolation and Protective Action Distances) has two entries for it: “Bromine trifluoride (when spilled on land)” and “Bromine trifluoride (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 gases produced: HF (hydrogen fluoride) and Br2 (bromine). Its guide number 144 has no P.
