Since I moved to North Dakota I have worked at two places: A hospital and a community mental health center. Both had Code announcements over the loudspeaker system that let you know that there was trouble or alerted you to an issue. Code Blue, at the hospital, meant that someone was in cardiac arrest. Code Brown at both facilities meant that there is a tornado coming and you should take shelter. Code Black means there is a bomb threat.
My current agency is redoing its Codes to align with those of other State agencies. One of my coworkers suggested that we should have a Code S (sleep), which would mean that we should all take 20 minute naps. I suggested that we should have Code Orange, which means that 45 is coming for a photo op and that we should all hide.
Please come up with some creative Codes to alert people to things they should know about.
