Also, survival kits are used in cases of bad weather.

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

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.

Lifeboat survival kits are stowed in inflatable or rigid lifeboats or life rafts; the contents of these kits are mandated by coast guard or maritime regulations. These kits provide basic survival tools and supplies to enable passengers to survive until they are rescued. In addition to relying on lifeboat survival kits, many mariners will assemble a "ditch bag" or "abandon ship bag" containing additional survival supplies. Lifeboat survival kit items typically include:

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

The US Army uses several basic survival kits, mainly for aviators, which are stored in canvas carrying bags. Aviators in planes with ejection seats have survival kits in the seat pan and the survival vest (SRU-21P) worn by US helicopter crews also contains some basic survival items.

"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, a fishing hook and fishing line, a large plastic garbage bag, a small vial of bleach, a small candle, a jigsaw blade, an Exacto knife blade, and a safety pin. Pre-packaged survival kits may also include instructions in survival techniques, including fire-starting or first aid methods. In addition, parachute cord can be wrapped around the tin. The parachute cord 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.

Another level in 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 an extra “reserve” gas tank. Some survivalists also carry a small (e.g., 250 cc) off-road-capable motorcycle in the van or truck.

Food supplies in the 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.

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.
