3191 on a placard, orange panel or shipping paper
It can stand for either of two ERG 2024 entries: “Self-heating solid, poisonous, inorganic, n.o.s.” and “Self-heating solid, toxic, inorganic, n.o.s.”. Both use Guide 136, so the number alone is enough to find the guide. On a numbered orange panel, 3191 is the lower number (how to read an orange panel).
