ERG 2024 lists UN/NA 1689 (Sodium cyanide, solid) under Guide 157, titled “Substances - Toxic and/or Corrosive (Non-Combustible/Water-Sensitive)”.
Material name
1689 on a placard, orange panel or shipping paper
It points to the ERG 2024 entry “Sodium cyanide, solid” and to Guide 157. On a numbered orange panel, 1689 is the lower number (how to read an orange panel).
ERG 2024 markings for 1689
1689 is highlighted in green, so ERG 2024 Table 1 (Initial Isolation and Protective Action Distances) has an entry for it: “Sodium cyanide, solid (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: HCN (hydrogen cyanide). Its guide number 157 has no P.
