2209 on a placard, orange panel or shipping paper

It can stand for either of two ERG 2024 entries: “Formaldehyde, solution (corrosive)” and “Formalin (corrosive)”. Both use Guide 153, so the number alone is enough to find the guide. On a numbered orange panel, 2209 is the lower number (how to read an orange panel).
