Material name
1855 on a placard, orange panel or shipping paper
It can stand for either of two ERG 2024 entries: “Calcium, pyrophoric” and “Calcium alloys, pyrophoric”. Both use Guide 135, so the number alone is enough to find the guide. On a numbered orange panel, 1855 is the lower number (how to read an orange panel).
