A survival kit is a package of basic tools an supplies prepared in advance as an aid to survival in an emergency. Military aircraft, lifeboats, and spacecraft are equipped with a survival kit. Civilians such as forestry workers, surveyors, or bush pilots, who work in remote locations or in regions with extreme climate conditions may also be equipped with survival kits. Disaster supplies kits are also kept on hand by those who live in areas prone to earthquakes or other natural disasters.
