I'm a Trader by profession. Keeping emergency funds in equities is a terrible idea imho. I would have to aggressively dismiss it and am pretty shocked it is being supported in any form.
The order of safety would go along the lines of:
Short term US debt, up to 2/5/10yr Treasury
German 2/5/10 yr debt.
USD denominated bank account with a top rated bank.
Smaller funds should look at the "safe" banks and spread the funds in short term demand accounts. E.g. BOI over AIB as they have cleared up their book much more strongly.
Equities would be way down the list. Way down.
Edit: A GFC is not needed for a blue chip stock to collapse 50% in value. Check out the movement in the following shares over the last two years. Each would have been viewed as blue chip but have been damaged due to one scandal or another:
VW
Tesco
Deutsche Bank
BHP Billiton
Toshiba
