UN/NA 2455

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.

Material Names

  • Methyl nitrite

There are no initial isolation and protective action distances listed in the ERG.

The ERG doesn't predict that large amounts of toxic-by-inhalation gases will be produced if this material is spilled in water.

The Hazmat Table in 49 CFR 172.101 "lists and classifies those materials which the Department (of Transportation) has designated as hazardous materials for purposes of transportation".

UN/NA datasheets display several items from the Hazmat Table: proper shipping names, hazard classes and divisions (explosives may also include a compatibility group letter), label codes, and special notes relating to shipping location, shipping name, and whether the material is an inhalation hazard.

Descriptive text for each label code is shown below the table, along with representative vehicle placards.

Note: UN/NA 2455 doesn't appear in the 49 CFR Hazmat Table.
