Material name
1941 on a placard, orange panel or shipping paper
It can stand for either of two ERG 2024 entries: “Dibromodifluoromethane” and “Refrigerant gas R-12B2”. Both use Guide 171, so the number alone is enough to find the guide. On a numbered orange panel, 1941 is the lower number (how to read an orange panel).
