Now I've been Googling for how the emergency might be announced over the PA system, and I'm thinking that it MIGHT be a 'code orange'. At least that's what some hospitals use for a "hazardous chemical spill." Other hospitals use it for a bomb threat.
I'm just wondering whether I'm right about calling it a code orange, whether there's a better code, or, barring that, if I choose to invent a code, which colors are currently "free" and won't be unintentionally humorous? (I've got a funny feeling that announcing a 'code periwinkle' just wouldn't work well.)
