UN/NA 2191 · Sulfuryl fluoride

Material name

2191 on a placard, orange panel or shipping paper

It can stand for either of two ERG 2024 entries: “Sulfuryl fluoride” and “Sulphuryl fluoride”. Both use Guide 123, so the number alone is enough to find the guide. On a numbered orange panel, 2191 is the lower number (how to read an orange panel).
