the Zürcher Unterland at the time. When the airport was privatized in 2000 to form the public limited company Unique (Flughafen Zürich AG), the rescue service was then separated from the fire service as a separate division within the Safety&Security department. In the last year of its existence in 2007, the Rescue Service at Zurich Airport carried out around 5800 missions with 36 paramedics and three trainees. The majority of the operations were carried out in the region around the airport, which at that time comprised 28 contractual communities. There were three ambulances on standby during the day and two ambulances at night, which was carried out in two shifts of twelve hours each. The teams were on duty four times a day (twice a day and twice at night). As a novelty, Zurich Airport Emergency Medical Services consistently applied the amended labor law, i.e. it was one of the few employers to fully credit the working time of twelve hours without deductions ("attendance time"/effective working time). There was no permanently installed emergency medical system at the airport site. The paramedics are equipped with extended skills that allow the administration of medication according to algorithms. As part of a quality control of the measures carried out, all operations were checked by the medical director. At the same time, an annual review of medication and algorithmic knowledge took place. Only after passing the written and practical test was the paramedic authorized to administer medication for another year. If an emergency physician was needed, the resources of the partner organisations REGA (helicopters) or the NEF of "Schutz und Rettung Zürich" could be called upon. Project SUS After two project studies, Unique (Flughafen Zürich AG) decided in the summer of 2007 to outsource the rescue service together with the operations centre and the professional fire brigade and to sell it to the Schutz und Rettung (Protection and Rescue) department of the city of Zürich for an amount of CHF 22 million. This was also due to the needs of the city of Zürich, as its professional fire brigade in particular had problems meeting the required arrival times with long journeys to the north of the city of Zürich. At the same time, it was possible to avoid the cost-intensive construction of a new base for rescue services and fire brigades in the rapidly growing north. A comprehensive contract was drawn up for the
