ERG 2024 lists UN/NA 3361 (Chlorosilanes, poisonous, corrosive, n.o.s.) under Guide 156, titled “Substances - Toxic and/or Corrosive (Combustible/Water-Sensitive)”.
Material name
3361 on a placard, orange panel or shipping paper
It can stand for either of two ERG 2024 entries: “Chlorosilanes, poisonous, corrosive, n.o.s.” and “Chlorosilanes, toxic, corrosive, n.o.s.”. Both use Guide 156, so the number alone is enough to find the guide. On a numbered orange panel, 3361 is the lower number (how to read an orange panel).
ERG 2024 markings for 3361
3361 is highlighted in green, so ERG 2024 Table 1 (Initial Isolation and Protective Action Distances) has an entry for it: “Chlorosilanes, poisonous, corrosive, n.o.s. (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 156 has no P.
