ERG Guide 153 Datasheet (for unassigned UN/NA numbers)

Emergency Response Guidebook (ERG, 2020)

The Emergency Response Guidebook (ERG) provides general response recommendations for first responders.

UN/NA datasheets display several items from the ERG: material names, response guide PDFs, initial isolation and protective action distances, warnings about toxic-by-inhalation gases that may be produced if the material spills in water, and polymerization hazards.
