1340 on a placard, orange panel or shipping paper
It can stand for either of two ERG 2024 entries: “Phosphorus pentasulfide, free from yellow and white phosphorus” and “Phosphorus pentasulphide, free from yellow and white phosphorus”. Both use Guide 139, so the number alone is enough to find the guide. On a numbered orange panel, 1340 is the lower number (how to read an orange panel).
ERG 2024 markings for 1340
1340 is highlighted in green, so ERG 2024 Table 1 (Initial Isolation and Protective Action Distances) has an entry for it: “Phosphorus pentasulfide, free from yellow and white phosphorus (when spilled in water)”. Hazora shows those distances in the app, not on this page. “When spilled in water” means the material produces large amounts of toxic inhalation hazard (TIH) gases when spilled in water. Table 2 (Water-Reactive Materials Which Produce Toxic Gases) lists the gas produced: H2S (hydrogen sulfide). Its guide number 139 has no P.
