ERG 2024 lists UN/NA 1769 (Diphenyldichlorosilane) under Guide 156, titled “Substances - Toxic and/or Corrosive (Combustible/Water-Sensitive)”.
Material name
1769 on a placard, orange panel or shipping paper
It points to the ERG 2024 entry “Diphenyldichlorosilane” and to Guide 156. On a numbered orange panel, 1769 is the lower number (how to read an orange panel).
ERG 2024 markings for 1769
1769 is highlighted in green, so ERG 2024 Table 1 (Initial Isolation and Protective Action Distances) has an entry for it: “Diphenyldichlorosilane (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.
