ERG 2024 lists UN/NA 2232 (Chloroacetaldehyde) under Guide 153, titled “Substances - Toxic and/or Corrosive (Combustible)”.
Material name
2232 on a placard, orange panel or shipping paper
It can stand for either of two ERG 2024 entries: “Chloroacetaldehyde” and “2-Chloroethanal”. Both use Guide 153, so the number alone is enough to find the guide. On a numbered orange panel, 2232 is the lower number (how to read an orange panel).
ERG 2024 markings for 2232
2232 is highlighted in green, so ERG 2024 Table 1 (Initial Isolation and Protective Action Distances) has an entry for it: “Chloroacetaldehyde”. Hazora shows those distances in the app, not on this page. Its guide number 153 has no P.
