ERG 2024 lists UN/NA 1741 (Boron trichloride) under Guide 125, titled “Gases - Toxic and/or Corrosive”.
Material name
1741 on a placard, orange panel or shipping paper
It points to the ERG 2024 entry “Boron trichloride” and to Guide 125. On a numbered orange panel, 1741 is the lower number (how to read an orange panel).
ERG 2024 markings for 1741
1741 is highlighted in green, so ERG 2024 Table 1 (Initial Isolation and Protective Action Distances) has two entries for it: “Boron trichloride (when spilled on land)” and “Boron trichloride (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: HCl (hydrogen chloride). Its guide number 125 has no P.
