What is your practice for storing  nitric and hydrochloric acids?  Do 
you keep them separated to prevent mixing?

I realize they are intentionally mixed to make aqua regia, (under 
controlled conditions using a fume hood).  But this evolves chlorine and 
nitrosyl chloride gases...so there is a concern about storing these two 
acids together.

I plan to tell our users that it's okay to keep these two acids in the 
same storage cabinet but that they should be kept on the same shelf and 
in individual photo trays to prevent accidental mixing in the event of a 
spill, leak etc.
