UN/NA 1786 · Hydrofluoric acid and sulfuric acid mixture

Material name

1786 on a placard, orange panel or shipping paper

It can stand for any of four ERG 2024 entries: “Hydrofluoric acid and sulfuric acid mixture”, “Hydrofluoric acid and sulphuric acid mixture”, “Sulfuric acid and hydrofluoric acid mixture” and “Sulphuric acid and hydrofluoric acid mixture”. All use Guide 157, so the number alone is enough to find the guide. On a numbered orange panel, 1786 is the lower number (how to read an orange panel).
