ERG 2024 lists UN/NA 1556 (Arsenic compound, liquid, n.o.s.) under Guide 152, titled “Substances - Toxic (Combustible)”.
Material name
1556 on a placard, orange panel or shipping paper
It can stand for either of two ERG 2024 entries: “Arsenic compound, liquid, n.o.s.” and “Methyldichloroarsine”. Both use Guide 152, so the number alone is enough to find the guide. On a numbered orange panel, 1556 is the lower number (how to read an orange panel).
ERG 2024 markings for 1556
1556 is highlighted in green, so ERG 2024 Table 1 (Initial Isolation and Protective Action Distances) has an entry for it: “Methyldichloroarsine”. Hazora shows those distances in the app, not on this page. Its guide number 152 has no P.
