What does the 4-digit UN/NA number link to when using the ERG?

The ERG uses a four-digit UN/NA number as a quick lookup key to the material’s emergency guidance. That number points you to the specific entry for that material, which lays out the hazards you’re dealing with and the protective actions to take at the scene. It tells you what to do right away—such as isolating the area, what PPE and containment steps are appropriate, and how to respond to spills or releases. It’s not about the molecular formula, regulatory approval status, or the color of a shipping label.
