Fire and Heat covers the practical knowledge, vocabulary, decisions, and field judgment needed for fire and heat 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.
This topic matters because small decisions made early can determine whether people stay warm, hydrated, oriented, fed, and visible to rescuers.
For InfoPreserver, fire and heat 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.
Fire is a tool, not a default answer. First decide whether warmth, cooking, drying, signaling, or water treatment is actually needed. Then choose the smallest controllable heat source that meets the need. Keep people out of smoke, keep fuel and sparks away from the shelter, and keep a way to extinguish the fire immediately available.
If a fire, stove, lantern, generator, or heater is producing smoke indoors, move people to fresh air and treat the situation as dangerous. Carbon monoxide cannot be seen or smelled reliably. Headache, dizziness, weakness, nausea, confusion, unusual sleepiness, or loss of coordination may indicate poisoning. Get to fresh air and seek emergency help; do not re-enter until the hazard is controlled.
A dependable fire system has six parts: a safe site, prepared fuel, ignition, airflow, containment, and extinguishing. If one part is missing, the fire becomes harder to control and less useful.
Fuel size changes the behavior of a fire. Fine material starts quickly but burns rapidly; larger pieces provide longer heat but need a stable coal bed and adequate draft. Wet fuel creates smoke and may cause people to increase the fire beyond safe limits. Sort fuel by starting material, steady heat, and long-duration heat. Keep reserve fuel dry and away from sparks, children, sleeping areas, and food.
Reflective surfaces, windbreaks, pot skirts, insulated containers, thermal mass, and retained-heat cooking can increase useful heat without increasing flame size. Never place improvised reflective material where it can overheat wiring, fabrics, fuel containers, or skin.
Heating a shelter is different from building an outdoor fire. A tent, vehicle, room, snow shelter, or improvised enclosure can accumulate smoke and carbon monoxide even when a door or vent is partly open. Use only equipment approved for the space and follow its instructions. Outdoor stoves, charcoal grills, generators, and fuel-burning heaters must remain outdoors and away from openings unless a purpose-built installation provides safe exhaust and ventilation.
Ventilation must remain open while combustion is occurring, but an opening can also admit wind, rain, sparks, or cold air. Balance these hazards with a designed flue or move the heat source outside. Never close a damper or cover a vent to “hold in heat” while fuel is still burning.
Dry clothing, bedding, fuel, and tools gradually. Keep textiles far enough from the fire to prevent ignition and turn them often. Do not dry synthetic materials, batteries, pressurized containers, or unknown plastics directly beside a flame. Stones, bricks, water containers, and insulated pots can store heat, but they may crack, burst, or cause burns. Test materials cautiously and mark hot objects clearly.
Before each use inspect hearths, grates, pot supports, handles, flues, chimneys, fuel lines, seals, and ventilation openings. Remove ash when it blocks airflow, but store ash only after it is cold in a noncombustible container. Look for creosote, soot, cracked masonry, loose supports, melted insulation, fuel leaks, and damaged cords. A fire system that cannot be inspected and repaired with available tools is not ready for sustained use.
Assign a fire keeper, fuel keeper, water or cooking operator, and extinguisher monitor during training. Practice lighting, feeding, moving a pot, responding to smoke, and extinguishing the fire. Record fuel used, heat produced, cooking or drying time, weather, and failures. These observations help a group ration fuel and choose between fire, stove, solar heat, retained heat, or no-cook methods.
Future additions should explain fire and heat 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.
