Planning
Provide separate air openings protected from soil, vegetation and water. The secondary exit leads independently outside and opens from within. An outside contact knows the location, occupancy and expected end time.
Emergency preparedness · 18 min
Minimum operation: air, exits and fire safety
Even a few hours in a small room require measurable air quality and two clear routes.
A basic room can omit comfort but not ventilation, CO₂ and smoke warning, lighting and escape routes. Timber, textiles and batteries add fire load; flames, stoves and engines remain entirely outside.

Decision compass
Decide safely
Four questions lead from observation to a clear, safer action.
What needs to be clarified now?
What must I notice first?
- Record household needs, dependencies, current official information and available safe locations.
- Agree responsibilities, communication rules and a fallback before time pressure develops.
Remember: Observe → assess → choose a safer option → act.

Learning goals
- Check two exits, supply and extract air, and alarm responses before occupancy
- List nearby hazards and every connected system
- Record the test result, responsible person and maintenance date
Inspection
Test airflow, CO₂ monitor, smoke alarm, emergency light and both exits before occupancy. Never lock people in. Unknown odours, headache, dizziness, alarm or a blocked exit require immediate evacuation.
Operation and maintenance
Inspect openings, sensors, batteries and routes frequently. Cooking, heating and charging large batteries takes place in a separate safe outside area.
Practical check
- Check two exits, supply and extract air, and alarm responses before occupancy
- Record conditions with photographs and a plan
- Assign responsibility
- Test function under realistic conditions
- Document results and maintenance date
Important
- Do not build without required specialist design
- Never trade escape routes or safe air for storage
- Do not present unverified assumptions as protective performance
Decision training
What must be checked before work begins on “Minimum operation: air, exits and fire safety”?
- ABuild immediately by improvisation
- BDocument conditions, obtain the required assessment and then test
- CPostpone the issue until an emergency
Show answer
Correct: B. Photographs, plans, specialist checks and a functional test show whether the proposed solution works safely at the actual site.
