Emergency Response Guide

The Emergency Response Guide (ERG) solution allows you to determine potential hazards based on the type of hazardous material spill and user-selected location on the map. It references the 2016 Emergency Response Guidebook (ERG).

This solution illustrates how you can:

  • Search for any material in the 2016 Emergency Response Guidebook by name or UN/NA ID number, similar to the yellow and blue look-up pages.
  • Provide the Response Guide page from the ERG in the browser for responders.
  • Create Initial Isolation and Protective Action Zone graphics based on spill location and weather conditions, similar to the orange guide pages and the green table pages, including:
    • Table I: Initial Isolation and Protective Distances
    • Table III: Large Spills of Toxic if Inhaled Gases
    • Boiling Liquid Expanding Vapor Explosion (BLEVE)
  • Use additional widgets to further assess the situation.
  • Publish the graphic to ArcGIS Enterprise or Portal for ArcGIS for dissemination and record-keeping.
