[QUOTE=essxjay;6858088]Quite high, actually.
A leaky pop bottle filled with standard household bleach placed near a similarly leaky container of standard household ammonia = bad thing. It's not wise to store them in the same cupboards at home, let alone allow them to mingle in a public trash bin along with heaven knows what else at an airport security CP.
The thing is your probably going to smell the bleach or ammonia if its leaking and those two liquids are handled in a totally different way than ordinary liquids because they are considered hazmat.
