One of the companies I work for deals with international shipping. One of the most interesting parts of that job is watching all the weird and dangerous commodities that ship across the roads, rails, and sea.
While most people are blissfully ignorant of what signs like these on a side of a truck mean, I have learned that the code identifies the specific commodity that is hazardous on the truck.
I do a lot of cross country driving and a tool I’ve always wanted for my iPhone is a HazMat lookup guide, so I can find out what trucks are carrying. A program like this also has uses not just for the curious like me, but also for people in the industry who work with these hazardous materials, and first responders.
So with that in mind, shortly after the SDK, as a part time diversion, I wrote HazMat for the iPhone.
