Sark is a car-free island. So the emergency services are quite peculiar on this island. A resident doctor provides healthcare on Sark, and is available to attend accidents and emergencies. The Sark Ambulance Service operates two tractor-drawn ambulances, and is able to treat casualties and transport them to the harbour for transfer onto the Guernsey marine ambulance launch, Flying Christine III, operated by Guernsey Ambulance and Rescue Service. A small ambulance station houses the two ambulances. Fire and rescue services are provided by an independent and volunteer service established in 1958. Originally named 'Sark Fire Brigade', it is now known as the Sark Fire and Rescue Service. The services operates two pump tenders and an all-purpose trailer; all three appliances are drawn by tractors owing to the ban on other motor vehicles on Sark. The original fire station was a large garage. Today the service operates from a large purpose-built fire station on La Chasse Marette. Lifeboat services are provided by the Royal National Lifeboat Institution from the Guernsey lifeboat station, supported by the RNLI stations on Jersey and Alderney.
