A survival kit is a package of basic tools and supplies prepared as an aid to survival in an emergency. Civil and military aircraft, lifeboats, and spacecraft are equipped with survival kits.

Survival kits, in a variety of sizes, contain supplies and tools to provide a survivor with basic shelter against the elements, help them to keep warm, meet basic health and first aid needs, provide food and water, signal to rescuers, and assist in finding the way back to help. Supplies in a survival kit normally include a knife (often a Swiss army knife or a multi-tool), matches, tinder, first aid kit, bandana, fish hooks, sewing kit, and a flashlight.

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 are also kept on hand by those who live in areas prone to earthquakes or other natural disasters. For the average citizen to practice disaster preparedness, some towns will have survival stores to keep survival supplies in stock.

The American Red Cross recommends an emergency preparedness kit that is easy to carry and use in the event of an emergency or disaster.^[1][2][3]

Mini survival kits or "Altoids" tin survival kits are small kits that contain a few basic survival tools. These kits often include a small compass, waterproof matches, minimum fishing tackle, large plastic bag, small candle, jigsaw blade, craft knife or scalpel blade, and/or a safety pin/s. Pre-packaged survival kits may also include instructions in survival techniques such as fire-starting or first aid methods. In addition, paracord can be wrapped around the tin. The paracord can be used for setting up an emergency shelter or snaring small animals. They are designed to fit within a container roughly the size of a mint tin.

Other small kits are wearable and built into everyday carry survival bracelets or belts. Most often these are paracord bracelets with tools woven inside. Several tools such as firestarter, buckles, whistles and compass are on the exterior of the gear and smaller tools are woven inside the jewelry or belt and only accessible by taking the bracelet apart.

Lightweight survival kits are generally seen as a backup means of survival; however, these kits can be extensive, and have come to include tools that are generally found in larger kits as survival technology advances. Some examples of these tools are high-power flashlights, rapid use saws, signal devices such as mini signal mirrors, and water purification methods.

An emergency kit, disaster bag, bug-out bag (BOB),^[4][5][6] also known as a 72-hour kit,^[7] GOOD bag (get out of Dodge),^[8][9] personal emergency relocation kit (PERK), go-bag, survival backpack, or quick run bag (QRB)^[10][11] is a portable kit containing items that would help a person to survive for 72 hours^[12] during an escape or evacuation from an emergency event or disaster such as a hurricane, earthquake, or flood.^[13]

The focus is on evacuation rather than long-term survival. The kits are also popular in the survivalism subculture.^[14]

The term "bug-out bag" is related to, and possibly derived from, the "bail-out bag" emergency kit many military aviators carry. In the United States, the term refers to the Korean War practice of the U.S. Army designating alternative defensive positions, in the event that the units had to retreat. They were directed to "bug out" when being overrun was imminent. The term has since been adopted by military training institutions around the world, with standard operating procedures involving a bug-out location, a method of withdrawal, and the bare supplies needed to withdraw quickly but still survive in the field. The concept passed into wide usage among other military and law enforcement personnel, though the "bail-out bag" is as likely to include emergency gear for going into an emergency situation as for escaping an emergency.^[15]

The primary purpose of a bug-out bag is to allow one to evacuate quickly if a disaster should strike.^[16] It is therefore prudent to gather into a single place all of the materials and supplies that might be required to do this, such as a bag or a few storage containers. The recommendation that a bug-out bag contain enough supplies for 72 hours arises from advice from organizations responsible for disaster relief and management that it may take them up to 72 hours to reach people affected by a disaster and offer help.^[17] The bag's contents may vary according to the region of the user, as someone evacuating from the path of a hurricane may have different supplies from someone who lives in an area prone to blizzards, earthquakes, or wildfires.

In addition to allowing one to survive a disaster evacuation, a bug-out bag may also be used when sheltering in place ("bugging in") as a response to emergencies such as blackouts, house fires, tornadoes, and other severe natural disasters.

The Federal Emergency Management Agency (FEMA), the United States's agency responsible for disaster planning and emergency resource management, outlines the following list for a three-day basic emergency supply kit.^[18] Similar items can also be found from other national emergency response agencies.

The suggested contents of a bug-out bag vary and can also include weapons for defense from dangerous animals or people.^{[4][19][20][21]}

Survival kits for military aviators are often modified according to the environment of operations:

• In desert areas, survival kits may have more water and sunscreen, and have additional items such as shade hats, a compass, a whistle, medical equipment, tinder, matches, and sun glasses.

• In tropical areas, a survival kit may have mosquito head netting, additional insect repellent, anti-fungal cream, a machete, water purification tablets, foot powder, matches, a flint strike, a compass, a wire saw, a space blanket, medical equipment (gauze pads, elastic gauze bandage, antiseptic creams, anti-malaria tablets, anti-infection tablets, bandages, etc.), salt tablets, a fishing kit, snare wire, extra socks, a candle, a signal mirror, flares, a sewing kit, safety pins, tinder, tape, a whistle, and rations.

• In arctic or alpine areas, survival kits may have additional cold weather clothing (winter hats and gloves), sleeping bags, chemical "hand warmer" packets, sunglasses/snow goggles, snowshoes, a collapsible shovel, a snare wire for small animals, a frying pan, a camp stove, camp stove fuel, a space blanket, matches, a whistle, a compass, tinder, medical equipment, a flint strike, a wire saw, extra socks and a tent designed for arctic use.

• For personnel who are flying over large bodies of water, in addition to wearing a survival suit over cold water, a survival kit may have additional items such as a small self-inflating raft to get the aircrewman out of cold or predator infested waters, flotation vests, sea anchor, fishing nets, fishing equipment, fluorescent sea marking dye, pyrotechnical signals, a survival radio and/or radio-beacon, formerly a distress marker light replaced by a flashing strobe, formerly a seawater still^[24] or chemical desalinator kit now replaced by a hand-pumped reverse osmosis desalinator (MROD) for desalinating seawater, a raft repair kit, a paddle, a bailer and sponge, sunscreen, medical equipment, a whistle, a compass, and a sun shade hat.

The U.S. Army uses several basic survival kits, mainly for aviators, some of which are stored in carrying bags. Aviators in planes with ejection seats have survival kits in a vest and the seat pan. The survival vest worn by US helicopter crews also contains some basic survival items.

Astronauts are provided with survival kits due to the difficulty of predicting where a spacecraft will land on its return to Earth, especially in the case of an equipment failure. In early US space flights, the kit was optimised for survival at sea; the one provided for John Glenn on the first American orbital space flight in Friendship 7 contained "a life raft, pocket knife, signaling mirror, shark repellent, seawater desalting tablets, sunscreen, soap, first aid kit, and other items".^[25] A survival kit was provided for the Apollo program which was "...designed to provide a 48-hour postlanding (water or land) survival capability for three crewmen between 40 degrees North and South latitudes".^[26] It contained "a survival radio, a survival light assembly, desalter kits, a machete, sunglasses, water cans, sun lotion, a blanket, a pocket knife, netting and foam pads".^[27]

The kits provided for Soviet and Russian cosmonauts are optimised for survival in the temperate and sub-arctic mountains, forests and grasslands in the east of the country. Soyuz spacecraft kits include "food rations, water bottles, warm clothing, rope for making a shelter using the capsule's parachute, fish hooks and miscellaneous other survival gear". The TP-82 Cosmonaut survival pistol, was provided to defend against predators such as wolves or bears. It was able to fire conventional bullets, shotgun cartridges and flares; the folding stock could be used as a shovel and it also had a fold-out machete.^[28]

Another aspect of some preparedness plans are vehicle kits. In some cases, supplies and equipment may be loaded into vehicle such as a van or truck with bicycle racks and a reserve gas tank. Some survivalists also carry a small (e.g., 250 cc) off-road-capable motorcycle in the van or truck.^[29]

Food supplies in a bug-out vehicle include hundreds of pounds of wheat, rice, and beans, and enough honey, powdered milk, canned goods, bottled fruit, vitamins, dehydrated fruits and vegetables, salt, pepper, spices, and oil for several months. In addition, the kits often contain high-calorie energy bars, a cooking kit, utensils, liquid soap, and towels. The water supplies may include bottled water, filtering kit, bottles, collapsible water containers, and chlorine bleach for water purification. Food preparation and washing equipment may include items such as a grain grinder, a bread mixer, a strainer, a manual can opener, a steam canner with canning jars and O-rings, cutlery, knives, an electric 12-volt cooler icebox, kerosene lamps and heaters, kerosene or propane stoves, extra fuel, a clothes wringer, a foot-operated treadle sewing machine, and an electric hot plate (which would require an inverter to operate off a car battery).^{[citation needed]}

The medical supplies may include a blood pressure gauge, stethoscope, scissors, tweezers, forceps, disposable scalpels, two thermometers (oral and rectal), inflatable splints, bandages, sutures, adhesive tape, gauze, burn ointment, antibiotic ointment, aspirin, rubbing alcohol, ipecac syrup, sterile water, cotton rags, soap, and cotton swabs.^{[citation needed]}

The transportation items may include bicycles with off-road tires and suspension, emergency tools and spare auto parts (e.g., fuses, fan belts, light bulbs, head light, tire pump, etc.), and an inflatable raft with paddles.^{[citation needed]}

In addition, the kits may contain typical individual "survival kit" items, such as nylon tarps, extra clothes and coats, blankets, sleeping bags, matches or other fire starting equipment, a compass and maps, flashlights, toilet paper, soap, a pocketknife and bowie knife, a fishing kit, a portable camping stove, a power inverter, backpack, paper and pencil, a signaling mirror, whistle, cable saw, bleach, insect repellent, magnifying glass, rope and nylon cord, pulleys, and a pistol and ammunition.^{[citation needed]}

The communications equipment may include a multi-band receiver/scanner, a citizens band (CB) radio, portable "walkie-talkies" with rechargeable batteries, and a portable battery-powered television. The power supplies may include a diesel or gasoline generator with a one-month fuel supply, an auto battery and charger, extension cord, flashlights, rechargeable batteries (with recharger), an electric multimeter, and a test light. Defense items include a revolver, semi-automatic pistol, rifle, shotgun, ammunition, mace or pepper spray, and a large knife such as a KA-BAR or a bowie knife.^{[citation needed]}

Tools may include cutting tools such as saws, axes and hatchets; mechanical advantage aids such as a pry bar or wrecking bar, ropes, pulleys, or a 'come-a-long" hand-operated winch; construction tools such as pliers, chisels, a hammer, screwdrivers, a hand-operated twist drill, vise grip pliers, glue, nails, nuts, bolts, and screws; mechanical repair tools such as an arc welder, an oxy-acetylene torch, a propane torch with a spark lighter, a solder iron and flux, wrench set, a nut driver, a tap and die set, a socket set, and a fire extinguisher. As well, some survivalists bring barterable items such as fishing line, liquid soap, insect repellent, light bulbs, can openers, extra fuels, motor oil, and ammunition.^{[citation needed]}

Some survivalists also recommend keeping a get me home kit in the car and/or at work. This is a kit to enable a person to get back home from work in an emergency where all transport cars and public transport have broken down. It is designed around personal circumstances where, for example, a walk of 25 kilometres might be required from work to home.^{[citation needed]} The get me home kit can include, for example, enough water to get home, suitable walking shoes, a map (not electronic), enough food for 12 hours, clothing for adverse weather, etc.^{[citation needed]}

The term go-kit / go-pack is popular in the amateur radio service, especially in the Amateur Radio Emergency Service (ARES) and Radio Amateur Civil Emergency Service (RACES) communities, and describes a combination personal bug-out bag and portable amateur radio station. A personal go-kit generally takes some combination of units: a "one-day" (or "24 hour") kit, a "three day" (or "72 hour") kit that adds additional supplies, or a "one week kit" that adds yet additional personal items to the three-day kit. Any or all supports deploying the operator plus his or her privately owned self-contained radio communications setup.^[30]
