United Hatzalah ("united rescue" in Hebrew: איחוד הצלה) is a free, volunteer-based emergency medical services (EMS) organization based in Jerusalem, Israel. Its mission is to provide immediate medical intervention during the critical window between the onset of an emergency and the arrival of traditional ambulance assistance. It is one of many Hatzalah organizations in various parts of the world. United Hatzalah of Israel was founded in 2006 with the merger of several small local hatzalah organizations. It has grown to become the largest independent, non-profit, fully volunteer EMS organization in the world, with over 4,500 volunteer medics nationwide. The organization provides free services to all citizens regardless of race, religion, or national origin. With the help of its Uber-like GPS dispatch system and fleet of rapid response ambucycles, United Hatzalah has achieved an average response time of less than 3 minutes nationwide and 90 seconds in metropolitan areas. United Hatzalah's national command center in Jerusalem uses an advanced GPS-based dispatch technology to identify the closest and most qualified volunteers and routes them to the scene of an emergency through a mobile device application. Over 700 volunteers are outfitted with medically equipped motorcycles “ambucycles” capable of navigating around traffic jams to reach victims in as few as 90 seconds. The organization is funded exclusively through private charitable support. Within Israel, individuals may contact United Hatzalah through its direct emergency number, 1221; however, some dispatch information is received directly from national ambulance services. United Hatzalah in turn alerts and coordinates with local ambulances, Search and Rescue (SAR), fire, and police services, when necessary.
