### 1/5 — Does not Work

*2021-07-19*

The app no longer loads on my iPhone. I have the latest version and running iOS ver 14.7.

### 3/5 — Great, when works

*2022-02-08*

This is a great app but have noticed in the last year or so that it doesn’t always work. It won’t open past the first screen with USEPA/NOAA emblems. WISER and NIOSH pocket guide are good substitutes.

### 5/5 — Best app ever

*2022-09-05*

Life saving, i just ask UN numbers and all the information there What we hauling, or is it safe for us.

### 5/5 — Outstanding

*2018-07-15*

All of your reference guides are easily accessible from this one platform.

### 5/5 — Great Resource...

*2018-07-11*

I have been using this program for many years as a planning and response resource and it just keeps getting better. Having the app on my phone makes it even more convenient and useful.

### 5/5 — Best source of ChemHazards ever!

It's finally here. Thanks Guys. Every now and then someone actually makes an app that is worthwhile. It will probably save lots of lives.
