Type a UN number or material name — get the Emergency Response Guidebook (ERG) guide number back instantly, along with hazard class and packing group. Covers 100+ commonly shipped materials, no sign-up.
Start typing a UN number or material name above.
Every UN number maps to exactly one ERG guide number — a two- or three-digit reference to a standardized page in the Emergency Response Guidebook covering potential hazards, public safety distances, and initial response actions for that material or material family. This tool matches your UN number or material name against a database of common entries and returns that guide number directly, so you don't have to flip through the index first.
This tool returns the guide number only, not the full guide page content. Pair it with your current official ERG for the complete hazards, isolation distances, and response steps — or see the UN Number Lookup tool for the full browsable table.
This page matches exact UN numbers and known material names. HazMat Pro's Identify feature goes further — hold to speak or type a free-text description, like "smoking pallet of batteries after a forklift strike," and it resolves the material with full PPE and response guidance, fully offline.
Voice-powered Identify, plus placards, UN numbers, and ERG guide numbers — searchable and fully offline.
