UN/NA 2977 · Radioactive material, uranium hexafluoride, fissile

Material name

2977 on a placard, orange panel or shipping paper

It can stand for either of two ERG 2024 entries: “Radioactive material, uranium hexafluoride, fissile” and “Uranium hexafluoride, radioactive material, fissile”. Both use Guide 166, so the number alone is enough to find the guide. On a numbered orange panel, 2977 is the lower number (how to read an orange panel).

ERG 2024 markings for 2977

2977 is highlighted in green, so ERG 2024 Table 1 (Initial Isolation and Protective Action Distances) has an entry for it: “Radioactive material, uranium hexafluoride, fissile (when spilled in water)”. Hazora shows those distances in the app, not on this page. “When spilled in water” means the material produces large amounts of toxic inhalation hazard (TIH) gases when spilled in water. Table 2 (Water-Reactive Materials Which Produce Toxic Gases) lists the gas produced: HF (hydrogen fluoride). Its guide number 166 has no P.
