1975 on a placard, orange panel or shipping paper
It can stand for either of two ERG 2024 entries: “Nitric oxide and dinitrogen tetroxide mixture” and “Nitric oxide and nitrogen dioxide mixture”. Both use Guide 124, so the number alone is enough to find the guide. On a numbered orange panel, 1975 is the lower number (how to read an orange panel).
ERG 2024 markings for 1975
1975 is highlighted in green, so ERG 2024 Table 1 (Initial Isolation and Protective Action Distances) has an entry for it: “Nitric oxide and dinitrogen tetroxide mixture”. Hazora shows those distances in the app, not on this page. Its guide number 124 has no P.
