code orange
Medical facility warning
Code orange is a hospital alert indicating a mass casualty incident or hazardous material spill requiring emergency response protocols.
More broadly, it was one of the color-coded threat levels in the U.S.
Homeland Security Advisory System (2002–2011), signifying "high" terrorist threat risk—second only to code red.
The airport went to code orange after the threat was reported.
