ERG 2024 lists UN/NA 1018 (Chlorodifluoromethane) under Guide 126, titled “Gases - Compressed or Liquefied (Including Refrigerant Gases)”.
Material name
1018 on a placard, orange panel or shipping paper
It can stand for either of two ERG 2024 entries: “Chlorodifluoromethane” and “Refrigerant gas R-22”. Both use Guide 126, so the number alone is enough to find the guide. On a numbered orange panel, 1018 is the lower number (how to read an orange panel).
ERG 2024 markings for 1018
1018 is not highlighted in green (no Table 1 entry), and its guide number 126 has no P.
