ERG 2024 lists UN/NA 1432 (Sodium phosphide) under Guide 139, titled “Substances - Water-Reactive (Emitting Flammable And Toxic Gases)”.
Material name
1432 on a placard, orange panel or shipping paper
It points to the ERG 2024 entry “Sodium phosphide” and to Guide 139. On a numbered orange panel, 1432 is the lower number (how to read an orange panel).
ERG 2024 markings for 1432
1432 is highlighted in green, so ERG 2024 Table 1 (Initial Isolation and Protective Action Distances) has an entry for it: “Sodium phosphide (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: PH3 (phosphine). Its guide number 139 has no P.
