3303 on a placard, orange panel or shipping paper
It can stand for any of ten ERG 2024 entries: “Compressed gas, poisonous, oxidizing, n.o.s.”, “Compressed gas, poisonous, oxidizing, n.o.s. (Inhalation Hazard Zone A)”, “Compressed gas, poisonous, oxidizing, n.o.s. (Inhalation Hazard Zone B)”, “Compressed gas, poisonous, oxidizing, n.o.s. (Inhalation Hazard Zone C)”, “Compressed gas, poisonous, oxidizing, n.o.s. (Inhalation Hazard Zone D)”, “Compressed gas, toxic, oxidizing, n.o.s.”, “Compressed gas, toxic, oxidizing, n.o.s. (Inhalation Hazard Zone A)”, “Compressed gas, toxic, oxidizing, n.o.s. (Inhalation Hazard Zone B)”, “Compressed gas, toxic, oxidizing, n.o.s. (Inhalation Hazard Zone C)” and “Compressed gas, toxic, oxidizing, n.o.s. (Inhalation Hazard Zone D)”. All use Guide 124, so the number alone is enough to find the guide. On a numbered orange panel, 3303 is the lower number (how to read an orange panel).
ERG 2024 markings for 3303
3303 is highlighted in green, so ERG 2024 Table 1 (Initial Isolation and Protective Action Distances) has ten entries for it: “Compressed gas, poisonous, oxidizing, n.o.s.”, “Compressed gas, poisonous, oxidizing, n.o.s. (Inhalation Hazard Zone A)”, “Compressed gas, poisonous, oxidizing, n.o.s. (Inhalation Hazard Zone B)”, “Compressed gas, poisonous, oxidizing, n.o.s. (Inhalation Hazard Zone C)”, “Compressed gas, poisonous, oxidizing, n.o.s. (Inhalation Hazard Zone D)”, “Compressed gas, toxic, oxidizing, n.o.s.”, “Compressed gas, toxic, oxidizing, n.o.s. (Inhalation Hazard Zone A)”, “Compressed gas, toxic, oxidizing, n.o.s. (Inhalation Hazard Zone B)”, “Compressed gas, toxic, oxidizing, n.o.s. (Inhalation Hazard Zone C)” and “Compressed gas, toxic, oxidizing, n.o.s. (Inhalation Hazard Zone D)”. Hazora shows those distances in the app, not on this page. Its guide number 124 has no P.
