Hazmat Placards and Icons

It's good to know that others share my weird fascination with signs. Ian Albert has a page dedicated to hazmat placards:

I have the same issue. Well, stickers in general that is. But with these signs I’m going to have to be careful - I like to put them on my laptop, and it’s getting a bit sticky to put a RadioActive sticker on the back of hte Dell and not expect some bonehead in TSA confiscate the computer…

There’s a company near me that does signage like this. They have a trio of caution signs hung on the front of the building. One says, “Crowd Control” another says “Danger Control” the last says “Idiot Control”
