ERG 2024 lists UN/NA 1828 (Sulfur chlorides) under Guide 137, titled “Substances - Water-Reactive - Corrosive”.
Material name
1828 on a placard, orange panel or shipping paper
It can stand for either of two ERG 2024 entries: “Sulfur chlorides” and “Sulphur chlorides”. Both use Guide 137, so the number alone is enough to find the guide. On a numbered orange panel, 1828 is the lower number (how to read an orange panel).
ERG 2024 markings for 1828
1828 is highlighted in green, so ERG 2024 Table 1 (Initial Isolation and Protective Action Distances) has four entries for it: “Sulfur chlorides (when spilled on land)”, “Sulphur chlorides (when spilled on land)”, “Sulfur chlorides (when spilled in water)” and “Sulphur chlorides (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 gases produced: HCl (hydrogen chloride), SO2 (sulfur dioxide) and H2S (hydrogen sulfide). Its guide number 137 has no P.
