Planning
Separate supply and exhaust and place intakes away from depressions and exhaust sources. Protect openings from rain and animals without improperly reducing area. Inspection points need safe access.

Protect external air and service points
A small external component can disable an entire function inside.
Air terminals, cable entries, drainage, inspection ports and sensors face weather, vegetation and mechanical damage. Their position must account for water, exhaust, snow, animals and accidental impact.

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.
A small external component can disable an entire function inside.
Learning goals
- Map every external point to an internal function and keep it accessible
- List nearby hazards and every connected system
- Record the test result, responsible person and maintenance date
Inspection
Check clear area, damage, corrosion, water level and unambiguous identification. A simple airflow check confirms movement only; required airflow is verified with appropriate methods.
Operation and maintenance
Cut back vegetation and inspect after storms, snow and heavy rain. Maintain closures and seals and store spares dry.
Practical check
- Map every external point to an internal function and keep it accessible
- 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 “Protect external air and service points”?
- 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.
