What about multiple symbols? Which take precedence?

Well, then there's the  flammable symbol... 70% ethanol is going to be flammable, still, but isn't pyrophoric.  In an organic chem lab, I would store pyrophorics separately from 70% ethanol, but the GHS symbol is the same...

Good point; I thought of that after I sent the e-mail. I wonder if there are other examples of incompatibilities within GHS classes (for example, explosives?).
