PHMSA’s Emergency Response Guidebook (ERG) serves as the essential reference for first responders dealing with incidents involving dangerous goods or hazardous materials during the early stages of an emergency.
The ERG app acts as a helpful tool, derived from the most recent edition of the ERG, enabling responders to swiftly obtain crucial information when needed. It offers a categorized inventory of hazardous materials, detailing their ID numbers, general risks, and recommended safety measures.
In real-life situations, such as attending to a tipped-over tractor trailer showing a DOT hazmat placard, emergency personnel can utilize the app to promptly identify the substance linked to the placard and receive directions on how to respond appropriately.
The complete versions are accessible in English, French, and Spanish.
Disclaimer:
Currently electronic files, including the ERG App, cannot be substituted for hard copy documents to comply with the requirements of the Emergency Response Information requirements of Subpart G of Part 172. The intent of this regulation is to ensure that the emergency response information be provided together with the shipping paper in an accessible manner. In accordance with 49 CFR Part 107, Subpart B, a person interested in displaying emergency response information in alternate manner may request a special permit from the Associate Administrator for Hazardous Materials Safety.
App using tips
1. Familiarize Yourself with the Interface: Before an emergency, explore the app’s layout, including the search function, hazardous materials list, and navigation menus. This ensures quick access to critical information under pressure.
2. Use the Search Function: Enter the hazardous material’s ID number, name, or placard details in the search bar to instantly retrieve its profile, risks, and response guidelines.
3. Leverage Placard Identification: When responding to incidents like a tipped-over tractor trailer, use the app’s placard table or visual guide to match the DOT hazmat placard to the substance and access safety recommendations.
4. Check Response Guides: Each material is linked to a specific guide number. Review the corresponding guide for detailed instructions on evacuation distances, protective actions, and first aid measures.
5. Bookmark Frequently Used Materials: Save or bookmark commonly encountered hazardous materials for faster access during recurring response scenarios.
6. Use Offline Mode: Download the app’s data for offline use, as internet access may be unreliable at emergency sites. Verify that the app is updated to the latest ERG edition.
7. Cross-Reference with Physical ERG: While the app is a quick reference, use it alongside the physical ERG book for comprehensive details or in case of technical issues.
8. Stay Updated: Regularly check for app updates to ensure you have the latest hazardous materials data and response protocols from the most recent ERG edition.
9. Practice Scenarios: Conduct training exercises using the app to simulate real-world incidents, such as identifying substances from placards or determining evacuation zones, to build confidence and proficiency.
