2857 on a placard, orange panel or shipping paper
It can stand for any of three ERG 2024 entries: “Refrigerating machines, containing ammonia solutions (UN2672)”, “Refrigerating machines, containing non-flammable, non-poisonous gases” and “Refrigerating machines, containing non-flammable, non-toxic gases”. All use Guide 126, so the number alone is enough to find the guide. On a numbered orange panel, 2857 is the lower number (how to read an orange panel).
