What’s New Version 2.1

Jayla's mod: clear the screen when the UN/NA number is invalid.

Description

This is a quick, free app to look up the four-digit "UN/NA" numbers on the hazmat placards affixed to highway and rail tankers. The chemical names and other information is shown. The main data is stored off-line, so it is available when there is no network connectivity. There are links to Wikipedia pages and official online information from NOAA in the US. This app was written for educational purposes only. Though this data is carefully derived from official US government web pages and is believed to be presented accurately, first responders and other life savers should probably rely on hazmat apps from official sources.

Jayla's mod: clear the screen when the UN/NA number is invalid.
Build 829148914v2.02018-11-02 09:07:20
A UN/NA number is sometimes a class of transported substances. When available the app now lists some of the chemicals in the class.
Build 828624031v1.92018-09-18 22:12:40
Fixed some keyboard input bugs, and updated the databases. Preparing for a Siri interface.
Build 826096829v1.42018-02-28 19:53:03
This app now uses a custom numeric keypad which shows only the digits with available information. The new keypad moves out of the way and may be restored by tapping the numbers field. ChesHaz now keeps a list of your substance queries in the app, which may be reviewed, edited, emailed, or cleared. Some layout issues and bugs were fixed.
Build 825956245v1.12018-02-10 02:27:57
