1143 on a placard, orange panel or shipping paper
It can stand for either of two ERG 2024 entries: “Crotonaldehyde” and “Crotonaldehyde, stabilized”. Both use Guide 131P, so the number alone is enough to find the guide. On a numbered orange panel, 1143 is the lower number (how to read an orange panel).
ERG 2024 markings for 1143
Every name under 1143 has guide number 131P; the P means the material may undergo violent polymerization.
1143 is highlighted in green, so ERG 2024 Table 1 (Initial Isolation and Protective Action Distances) has an entry for it: “Crotonaldehyde”. Hazora shows those distances in the app, not on this page.
