It’s a scam. The other ERG book is free like it should be. If this was the only app for this. I’d use the book instead. That’s free and can get updated books for free every year ### 1/5 — “Table 1” link in orange pages does not jump to table 1 *2021-09-20* “Table 1” link in orange pages does not jump to table 1. The “Table 1” link in the orange pages that is in a purple font does not jump to Table 1. All it will do is blink indicating a touch on the link was recognized, but it will not go to Table 1? Also in the search bar, if you type in “Table 1” noting is found..... Table 1 is pretty important since it tells the minimum Initial Isolation Distance for a HAZMAT accident scene. It would be nice to see this fixed very soon! I would hate to be a responder trying to use this at a train wreck or an overturned tanker truck and not be able to determine that basic information and putting everyone in that Initial Isolation zone at greater risk of exposure, injury or death. Think we can get that fixed development team? Thanks, A concerned firefighter and HAZMAT responder ### 1/5 — Haz May 2020 *2021-05-27* Don’t download this. It wants to charge you. Download ERG 2020 it is free and what public safety uses. ### 1/5 — Not Free to upgrade and get all information *2021-05-25* Not Free to upgrade and get all information ### 1/5 — Charges money. *2021-05-19* Do not download this one. Get the other one. The other ERG 2020 is free in its entirety. You are not allowed to charge for this material it is against the law. The person/people that uploaded this are absolutely wrong. ### 1/5 — Update equals automatic charge *2021-03-01* Not very happy when you click the update tab it automatically charges you money without asking if you want to proceed with the purchase. Makes it feel more like a setup than you buying a product you may actually want. ## Most critical reviews (10 lowest-rated) ### 1/5 — Free version exists *2026-05-14* Downloaded this because it came up first in my search but you have to pay them to unlock all pages. There is an official FREE ERG available by USDOT ### 1/5 — CAUTION!! Not the FREE app by D.O.T. *2026-05-13* I downloaded this because I thought it was the free ERG DOT app. IT IS NOT!! This is a PAY app, and quite ridiculous at that. Why pay $30 annually for information that is already free? If you want to pay for free stuff fine, but if you want the free ERG look for that app instead. ### 1/5 — Robb189 *2024-09-10* Paid for the premium. It’s not up to date. ### 1/5 — This isn’t the official app they want to charge to view this there a scam *2024-04-22* PLEASE DONT DOWNLOAD!!! Use free app by the US department of transportation and pipeline administration The free official app is “ERG 2024” or “ERG FOR IOS” IS A FREE APP BY THE US DEPARTMENT OF TRANSPORTATION. They have rail cars trailers and placards This app wants to charge a $10 one time fee to unlock guides ### 1/5 — App outdated. *2023-09-05* This app is outdated. Please download ERG for iOS by the national institute for pipeline safety for updated information. ### 1/5 — Offer’s In-App Purchases *2022-09-29, version 1.146* Whose stupid idea was that? It’s bad enough to be asked to review an app, but having to say, “hold on, we’ll see how far to evacuate you as soon as I can get through these ads.” Not to mention any banners or ads may cause confusion with the instructions needing to be provided. This APP needs to be 100% ad free at all times. Without purchase to upgrade to that. ### 1/5 — Upgrade charge without warning *2022-09-21* Do not upgrade if you do not want to spend $13.99. Unable to refund! Did not have a warning.. also poor navigation, cannot access table 1,2,3 etc ### 1/5 — What a joke *2022-08-12* They don’t even have information on polyalumium chloride ### 1/5 — Scam *2022-04-17* Not the real ERG app. $10 to unlock free and publicly available information. Glad I checked the app out before I actually needed it. ### 1/5 — What?! *2022-03-03* Why would I pay $10 for a book that is free and on our trucks! What a ripoff. ## Most praised reviews (9 highest-rated) ### 5/5 — Great for hazmat lessons *2024-09-13* I work as a teacher teaching year 9 students through a Google meet after school about hazmat training. This is a great app and has really helped them to achieve high grades on there exams and further learning opportunities ### 5/5 — Handy *2022-08-23* Being in the fire Dept and being that I’m volunteer this comes in handy when I pull up on scene with my personal vehicle. ### 5/5 — ERG 2020 *2022-04-12* Very informative ### 4/5 — Update *2024-05-06* This a a very useful tool while being on the job. However the 2024 version in print has been released . Why has the update for 2024 not been released for the app yet ? ### 4/5 — App is good *2022-02-07* Nice ### 2/5 — Review *2022-09-24* Very difficult to use compared to the old one. ### 2/5 — Ok but needs update *2022-08-28* The app works ok, you don’t need to upgrade to get the information. The selection buttons on the bottom are the same color as the bar they sit on so you don’t even know they are there. Just select next to the “Guide” and the other options are there. ### 2/5 — There is a free version *2022-04-21* “ERG for iOS” is the free version. ### 2/5 — Now paid program *2022-02-07* Was great when it was free, now $10 for the whole thing! --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
