Planning
Create an asset register with manufacturer, model, installation date, instructions, spares and owner. Critical functions need alternatives and clear limits. Define when the room is no longer suitable and must be left.

Maintain, handle failure and return
A shelter remains ready only through recurring checks, clear limits and documented handover.
The longest phase begins after completion: operation. Filters age, batteries lose capacity, seals harden, drains block and responsibilities change. A maintenance plan links dates to specific checks and responses.

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
- Define maintenance, failure and return as one process
- List nearby hazards and every connected system
- Record the test result, responsible person and maintenance date
Inspection
Use monthly, seasonal and annual inspections plus checks after heavy rain, power failure or alteration. Record readings and defects rather than merely ticking boxes. Overdue safety-critical work suspends use.
Operation and maintenance
After use, ventilate, clean, replenish and review the event log. Return to normal life also requires an honest decision about whether damage, contamination or fatigue needs further help.
Practical check
- Define maintenance, failure and return as one process
- 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 “Maintain, handle failure and return”?
- 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.
