ERG 2024 lists UN/NA 3356 (Oxygen generator, chemical) under Guide 140, titled “Oxidizers”.
Material name
3356 on a placard, orange panel or shipping paper
It can stand for either of two ERG 2024 entries: “Oxygen generator, chemical” and “Oxygen generator, chemical, spent”. Both use Guide 140, so the number alone is enough to find the guide. On a numbered orange panel, 3356 is the lower number (how to read an orange panel).
