# Emergency Shelter
Emergency Shelter covers the practical knowledge, vocabulary, decisions, and field judgment needed for emergency shelter within Core Survival. This page defines the topic broadly so the wiki can accept future manuals, diagrams, checklists, and local examples without narrowing the subject around a single document.
At this level of the library, the subject should be understandable to non-specialists and usable in difficult conditions. At A0, the subject must be usable under stress with little infrastructure, little time, and uneven training.
Shelter topics protect people, tools, food, records, and work areas from weather, heat loss, fire, moisture, pests, and structural hazards.
For InfoPreserver, emergency shelter should be treated as a working capability rather than a label. A reader should be able to understand what problem the topic solves, what conditions make it harder, what signs or measurements matter, what mistakes are common, and when the issue belongs in a more specialized folder.
Emergency shelter is a race against exposure. First reduce wind, rain, snow, sun, wet ground, and unsafe movement. Then improve insulation, ventilation, sanitation, and comfort. A shelter does not need to be permanent to save a life; it needs to be appropriate to the next hours and maintainable for as long as the group must remain there.
Before building, check for flooding, falling branches, unstable walls, loose rock, avalanche paths, wildfire, contaminated water, power lines, and vehicle traffic. Avoid low places that collect water or cold air, but do not place a shelter on a ridge or exposed crest when wind is the main danger. Keep an exit route open and tell another person where the shelter is located.
Choose the driest practical site with natural wind protection, drainage, nearby but not dangerously close fuel and water, and a route that can be seen or marked by rescuers. Keep sleeping, cooking, fuel storage, waste, and washing areas distinct. Do not place a latrine uphill or upstream from a water source. In a group shelter, provide a clear aisle, an accessible space for people with limited mobility, protected storage for medicines and records, and a location where instructions can be posted.
Every shelter should be evaluated against four questions:
Improving the roof while leaving people on wet ground is often the wrong priority. Dry bedding, floor insulation, and wind reduction usually produce more immediate benefit than adding size.
Use the simplest method that matches the conditions and the time available. A tarp, sheet, poncho, plastic, blanket, or salvage panel can form a windbreak or lean-to when its edges are anchored and water is directed away. Brush, leaves, grass, bark, clothing, cardboard, and spare materials can provide insulation, but they must be kept dry and replaced when compressed or wet.
Natural shelters can save labor but must be inspected for animals, falling material, flooding, poor air, and hidden structural weakness. Snow shelters can be effective insulators but require sound snow, an entrance that does not block, ventilation, a stable roof, and continuous monitoring for collapse or carbon monoxide. Never assume that a snow shelter is safe simply because it is quiet and warm.
More durable emergency structures may use poles, rope, earth, stone, salvaged boards, corrugated sheets, or woven materials. Keep structural loads simple, brace against racking, protect the roof from leaks, and leave room for maintenance. A shelter that cannot be repaired with available tools is a short-lived shelter.
Treat fire as a separate system from shelter. Open flames, charcoal, fuel-burning stoves, lanterns, and generators can ignite materials or produce carbon monoxide. Do not use outdoor appliances in tents, vehicles, basements, or other enclosed spaces. Provide a safe clearance, a stable base, a way to extinguish the fire, and ventilation that does not simply direct smoke into sleeping areas. Coordinate with the Emergency Cooking, Fire and Heat, and Cold Weather Survival pages.
Crowded shelters spread respiratory, gastrointestinal, and skin illness quickly. Establish handwashing or hand-cleaning points, safe water handling, waste removal, food separation, sleeping-space spacing, and a procedure for isolating illness. Keep wet clothing and bedding from becoming a persistent source of mold or cold injury. Protect children, older adults, pregnant people, disabled people, and medically vulnerable occupants when assigning sleeping locations and access routes.
Shelter is not always the safest choice. Follow official evacuation orders, leave before routes become impassable, and take essential medications, water, identification, communications, and a written contact plan. Shelter-in-place is a hazard-specific decision: the best room for a windstorm may not be the best room for smoke, flooding, chemical release, extreme heat, or a building fire. Monitor official instructions and preserve an exit option whenever possible.
Recheck the shelter after every major weather change and at regular intervals. Look for water paths, sagging, loose anchors, damaged insulation, blocked exits, smoke accumulation, condensation, spoiled food, full waste containers, and signs of pests. Record repairs and changes so the next shift can understand what was done. When a shelter becomes unsafe, move people first and salvage materials second.
Future additions should explain emergency shelter in a way that a reader can evaluate, teach, and adapt. Good candidates include field guides, checklists, illustrated procedures, training notes, safety guidance, tables of limits or warning signs, repair or maintenance examples, and public-domain or open-license manuals.
Avoid narrow documents that only mention the topic in passing. If a future PDF belongs partly here and partly somewhere else, keep one primary copy and add cross-links from the related pages. When a source is technical, add a short orientation note explaining prerequisite skills and the A-level where it becomes fully usable.
This page is currently placed in A0 Survival Baseline. If later documents prove that the topic needs simpler emergency treatment or a more advanced technical treatment, it can be split into lower- and higher-level pages without losing this broad orientation.
These links document current authorities and updates; the required local documents are listed above so users do not have to download material from outside sites to use this repository.
