ERG 2024 lists UN/NA 1806 (Phosphorus pentachloride) under Guide 137, titled “Substances - Water-Reactive - Corrosive”.
Material name
1806 on a placard, orange panel or shipping paper
It points to the ERG 2024 entry “Phosphorus pentachloride” and to Guide 137. On a numbered orange panel, 1806 is the lower number (how to read an orange panel).
ERG 2024 markings for 1806
1806 is highlighted in green, so ERG 2024 Table 1 (Initial Isolation and Protective Action Distances) has an entry for it: “Phosphorus pentachloride (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: HCl (hydrogen chloride). Its guide number 137 has no P.
