ERG 2024 lists UN/NA 3278 (Organophosphorus compound, liquid, poisonous, n.o.s.) under Guide 151, titled “Substances - Toxic (Non-Combustible)”.
Material name
3278 on a placard, orange panel or shipping paper
It can stand for either of two ERG 2024 entries: “Organophosphorus compound, liquid, poisonous, n.o.s.” and “Organophosphorus compound, liquid, toxic, n.o.s.”. Both use Guide 151, so the number alone is enough to find the guide. On a numbered orange panel, 3278 is the lower number (how to read an orange panel).
