Emergency management involves strategic organizational processes to protect critical assets from hazards and ensure continuity. Emergency medical services provide out-of-hospital medical care and transport for patients unable to transport themselves, going by names like ambulance services or life squads. Principles of emergency management include taking a comprehensive, progressive, risk-driven, integrated, collaborative, and coordinated approach that is flexible and professional. International organizations involved in emergency management include the International Association of Emergency Managers, Red Cross, United Nations, World Bank, European Union, and International Recovery Platform.
