A DOT hazmat placard is the diamond-shaped sign required on vehicles and containers transporting hazardous materials in the US, identifying the hazard class — like Flammable Liquid, Corrosive, or Explosives — by color, symbol, and class number under 49 CFR. HazMat Pro includes all 19 placard divisions with color, symbol, and handling notes.
A UN number is a four-digit code assigned by the United Nations to identify a specific hazardous material or class of materials during transport, such as UN1203 for gasoline or UN1830 for sulfuric acid. HazMat Pro's UN Numbers tab includes 55+ entries with shipping name, hazard class, packing group, and ERG guide number.
The Emergency Response Guidebook is the standard reference used by first responders during the initial phase of a hazmat transportation incident, jointly published by the US DOT, Transport Canada, and Mexico's SCT. It assigns each material a guide number with isolation distances and response guidance. HazMat Pro references current ERG guide numbers throughout its placard and UN number data.
No. HazMat Pro is a field reference and training aid meant to speed up lookups and build familiarity with placards, UN numbers, and terminology. It's not affiliated with the DOT or PHMSA and doesn't replace the current official ERG, your organization's SOPs, or CHEMTREC in an actual incident — always confirm against the current official guidebook before acting on this data in the field.
Yes, for almost everything. Placards, UN numbers, the glossary, and quick reference are all stored on-device. Identify resolves exact UN numbers and known shipping names offline too — only free-text or descriptive queries that aren't already in the local database need a network connection.
HazMat Pro is built for CDL drivers with a hazmat endorsement, dispatchers, warehouse and logistics staff, EHS and safety officers, and first responders who need a fast placard, UN number, or terminology lookup without carrying a physical guidebook.
No. HazMat Pro is a one-time purchase — no subscription, no ads, no in-app purchases.
