Symbols

After researching various paint brands and the production of aerosol cans in general, I couldn't help but notice regulatory symbols everywhere, many of  which I've grown up being told mean harmful, flammable or recyclable. Some are pretty self explanatory to an extent but I want to get a clear perspective of how and when they're used. I came across this rather rudimentary but helpful source.

In order to have a crisp (size adjustable) set of these symbols I'm going to spend a little time vectoring them opposed to using pixelated pictures from various sources. In order to gain a better understanding of how and when they're used I'll be doing some more primary research looking at existing cans.
