UN/NA 1040 · Ethylene oxide

Material name

1040 on a placard, orange panel or shipping paper

It can stand for either of two ERG 2024 entries: “Ethylene oxide” and “Ethylene oxide with nitrogen”. Both use Guide 119P, so the number alone is enough to find the guide. On a numbered orange panel, 1040 is the lower number (how to read an orange panel).

ERG 2024 markings for 1040

Every name under 1040 has guide number 119P; the P means the material may undergo violent polymerization.

1040 is highlighted in green, so ERG 2024 Table 1 (Initial Isolation and Protective Action Distances) has an entry for it: “Ethylene oxide”. Hazora shows those distances in the app, not on this page. 1040 is also one of the six common TIH gases in Table 3, which covers large spills by container type.
