1955 on a placard, orange panel or shipping paper
It can stand for any of thirteen ERG 2024 entries: “Compressed gas, poisonous, n.o.s.”, “Compressed gas, poisonous, n.o.s. (Inhalation Hazard Zone A)”, “Compressed gas, poisonous, n.o.s. (Inhalation Hazard Zone B)”, “Compressed gas, poisonous, n.o.s. (Inhalation Hazard Zone C)”, “Compressed gas, poisonous, n.o.s. (Inhalation Hazard Zone D)”, “Compressed gas, toxic, n.o.s.”, “Compressed gas, toxic, n.o.s. (Inhalation Hazard Zone A)”, “Compressed gas, toxic, n.o.s. (Inhalation Hazard Zone B)”, “Compressed gas, toxic, n.o.s. (Inhalation Hazard Zone C)”, “Compressed gas, toxic, n.o.s. (Inhalation Hazard Zone D)”, “Organic phosphate compound mixed with compressed gas”, “Organic phosphate mixed with compressed gas” and “Organic phosphorus compound mixed with compressed gas”. All use Guide 123, so the number alone is enough to find the guide. On a numbered orange panel, 1955 is the lower number (how to read an orange panel).
ERG 2024 markings for 1955
1955 is highlighted in green, so ERG 2024 Table 1 (Initial Isolation and Protective Action Distances) has thirteen entries for it: “Compressed gas, poisonous, n.o.s.”, “Compressed gas, poisonous, n.o.s. (Inhalation Hazard Zone A)”, “Compressed gas, poisonous, n.o.s. (Inhalation Hazard Zone B)”, “Compressed gas, poisonous, n.o.s. (Inhalation Hazard Zone C)”, “Compressed gas, poisonous, n.o.s. (Inhalation Hazard Zone D)”, “Compressed gas, toxic, n.o.s.”, “Compressed gas, toxic, n.o.s. (Inhalation Hazard Zone A)”, “Compressed gas, toxic, n.o.s. (Inhalation Hazard Zone B)”, “Compressed gas, toxic, n.o.s. (Inhalation Hazard Zone C)”, “Compressed gas, toxic, n.o.s. (Inhalation Hazard Zone D)”, “Organic phosphate compound mixed with compressed gas”, “Organic phosphate mixed with compressed gas” and “Organic phosphorus compound mixed with compressed gas”. Hazora shows those distances in the app, not on this page. Its guide number 123 has no P.
