Coles uses "code blue" for medical emergencies

A "code blue" announcement heard over a Coles supermarket loudspeaker indicates a medical emergency requiring first aid assistance. This was confirmed by a Coles spokesperson. The code alerts trained staff to provide aid to a customer in need. The announcement is made to discreetly inform staff of the situation and direct them to the location of the incident. The use of codes like "code blue" is intended to maintain privacy and prevent unnecessary panic. The practice is similar to that used in other non-medical settings.
