ERG 2024 lists UN/NA 2204 (Carbonyl sulfide) under Guide 119, titled “Gases - Toxic - Flammable”.
Material name
2204 on a placard, orange panel or shipping paper
It can stand for either of two ERG 2024 entries: “Carbonyl sulfide” and “Carbonyl sulphide”. Both use Guide 119, so the number alone is enough to find the guide. On a numbered orange panel, 2204 is the lower number (how to read an orange panel).
ERG 2024 markings for 2204
2204 is highlighted in green, so ERG 2024 Table 1 (Initial Isolation and Protective Action Distances) has an entry for it: “Carbonyl sulfide”. Hazora shows those distances in the app, not on this page. Its guide number 119 has no P.
