UN/NA 2845 · Ethyl phosphonous dichloride, anhydrous

Material name

2845 on a placard, orange panel or shipping paper

It can stand for any of three ERG 2024 entries: “Ethyl phosphonous dichloride, anhydrous”, “Methyl phosphonous dichloride” and “Pyrophoric liquid, organic, n.o.s.”. All use Guide 135, so the number alone is enough to find the guide. On a numbered orange panel, 2845 is the lower number (how to read an orange panel).

ERG 2024 markings for 2845

2845 is highlighted in green, so ERG 2024 Table 1 (Initial Isolation and Protective Action Distances) has two entries for it: “Ethyl phosphonous dichloride, anhydrous” and “Methyl phosphonous dichloride”. Hazora shows those distances in the app, not on this page. Its guide number 135 has no P.
