Material name
1725 on a placard, orange panel or shipping paper
It points to the ERG 2024 entry “Aluminum bromide, anhydrous” and to Guide 137. On a numbered orange panel, 1725 is the lower number (how to read an orange panel).
ERG 2024 markings for 1725
1725 is highlighted in green, so ERG 2024 Table 1 (Initial Isolation and Protective Action Distances) has an entry for it: “Aluminum bromide, anhydrous (when spilled in water)”. Hazora shows those distances in the app, not on this page. “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 137 has no P.
