When a code black was called, the bomb squad was called to the hospital

Hospital codes are codes used in hospitals to alert staff to various emergencies. The use of codes is intended to convey essential information quickly and with minimal misunderstanding to staff, while preventing stress and panic among the visitors to the hospital.

The meaning of a specific color code can vary from one hospital to another hospital. At this page, the meanings of the codes at Seattle Grace Hospital (and the hospitals later established in the building) and St. Ambrose Hospital are listed.
