Material name
3279 on a placard, orange panel or shipping paper
It can stand for either of two ERG 2024 entries: “Organophosphorus compound, poisonous, flammable, n.o.s.” and “Organophosphorus compound, toxic, flammable, n.o.s.”. Both use Guide 131, so the number alone is enough to find the guide. On a numbered orange panel, 3279 is the lower number (how to read an orange panel).
