## ERG for iOS Description
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.

## ERG for iOS Reviews in United States

### ***** "Add"
Great mapping, should integrate an auto wind direction
-- Nfjdiod, 2024-10-19

### ***** "Great app"
Works well! Cool functionality.
-- Ash9999D, 2024-04-02

### ***** "A great resource"
Eventually, you remember what the placards mean.
-- edmondcorbet, 2023-11-21

### ***** "Under Rated Free App"
This app functions better than most paid versions that are available.
-- Darn top, 2023-01-17

### ***** "Suggestions"
5 stars cause it’s super convent and handy! 

Only suggestion is making the wind direction option easier to maneuver.. could be a bit confusing to use :)
-- Whynotthisname3, 2022-07-08

### ****- "Dark mode for first responders"
Could use a dark mode for working on scene at night
-- killbam, 2022-04-07

### ***** "Suggestion"
This is a great app. So much better than the book. I suggest when in the orange section have the “protective distance” icon at the bottom green instead of grayed out and/or have the green highlighted area in the evacuation section a link to the protective distances. 

Great app
-- Great 10000, 2022-03-22

### ***** "Great Reference"
This is the standard reference for hazardous materials.
-- LouWestin, 2022-02-25
