ERG 2024 lists UN/NA 1834 (Sulfuryl chloride) under Guide 137, titled “Substances - Water-Reactive - Corrosive”.
Material name
1834 on a placard, orange panel or shipping paper
It can stand for either of two ERG 2024 entries: “Sulfuryl chloride” and “Sulphuryl chloride”. Both use Guide 137, so the number alone is enough to find the guide. On a numbered orange panel, 1834 is the lower number (how to read an orange panel).
ERG 2024 markings for 1834
1834 is highlighted in green, so ERG 2024 Table 1 (Initial Isolation and Protective Action Distances) has four entries for it: “Sulfuryl chloride (when spilled on land)”, “Sulphuryl chloride (when spilled on land)”, “Sulfuryl chloride (when spilled in water)” and “Sulphuryl chloride (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 137 has no P.
