Hi Carole,
This issue came up for me recently in a consulting assignment I had, and no one gave me a good answer. Many chemicals belong in more than one hazard category
(I believe there are nine total) and no one has indicated an order priority in how it is to be listed. Maybe there isn’t an order and the user has to be aware that the chemical has multiple, simultaneous hazards. Any further thoughts or references on this
matter you would care to share would be greatly appreciated.
Thanks,
Armen

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?).
