UN/NA 2940 · Cyclooctadiene phosphines

Material name

2940 on a placard, orange panel or shipping paper

It can stand for either of two ERG 2024 entries: “Cyclooctadiene phosphines” and “9-Phosphabicyclononanes”. Both use Guide 135, so the number alone is enough to find the guide. On a numbered orange panel, 2940 is the lower number (how to read an orange panel).
