I am on leave at the moment and don't have Jepps handy, but I will look at the Oz Jepps when I get back. They should not have any reference to "emergency" as PANS-OPS is applied in Australia and Ozzie rules consider the use of MSA to be a "normal" procedure.
What I was suggesting is that the view of the regulatory authority where you are may be different, and that Jepps are probably reflecting that view. Rather than taking Jepps at face value I was suggesting that you search the "source" regs for the answer to your original question.
I'd be interested to know the result. Most European countries apply PANS-OPS so the idea of the MSA being an emergency procedure is curious.
