PHMSA’s Emergency Response Guidebook (ERG) is the go-to resource for first responders during the initial phase of a dangerous goods or hazardous materials transportation incident. The ERG app is a valuable companion, based on the latest edition of the ERG, to help responders quickly access critical information at their fingertips. The app features an indexed list of dangerous goods, including their associated ID number, general hazards, and recommended safety precautions. In practical scenarios, such as responding to an overturned tractor trailer displaying a DOT hazmat placard, emergency responders can use the app to quickly identify the material associated with the placard and get guidance on how to respond effectively. Full versions available in English, French, and Spanish.

Verdict
The clearest difference is ratings volume: ERG for iOS at 64 against NSSF Events's 2. ERG for iOS also leads on monetization model (free vs ad-supported) and chart position (#125 vs unranked). NSSF Events's advantage is rating (5.0 vs 4.8) and update cadence (every 2 months vs every 4 months). On price, ads, in-app purchases and device support there is nothing between them.
