Chartered Medical Evacuation Travel (CMET) consists of obtaining highly specialized medical air ambulance services together with, as necessary, professional medical services to evacuate a critically ill staff member or dependent. CMET is to be used for the most critical emergencies and when commercial air transportation by the most direct and economical route (the normal mode for MET) is not sufficient to safeguard the staff member’s life. All Heads of Office should be fully briefed on CMET procedures, have all relevant contact numbers of medical officers, approving officers, International SOS and HQ contacts and are expected to be capable of acting quickly and correctly outside normal working hours.
