Planning
Choose approved devices for their intended purpose and locate them according to manufacturer and specialist guidance. Define responses: check air supply, avoid the source, warn occupants and leave if conditions are uncertain.
Emergency preparedness · 18 min
Monitor CO₂, CO, smoke and radon
Different hazards require suitable sensors, alarm thresholds and responses.
Carbon dioxide reflects occupancy and ventilation, carbon monoxide indicates dangerous combustion gases, smoke detection warns of fire and radon is a long-term site issue. No single device covers every hazard.

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.
Different hazards require suitable sensors, alarm thresholds and responses.
Learning goals
- Define sensors, locations and responses for each hazard
- List nearby hazards and every connected system
- Record the test result, responsible person and maintenance date
Inspection
Use built-in test functions, verify power and assess plausible readings during occupancy. Never test sensors with fire, exhaust or risky improvisation.
Operation and maintenance
Include batteries, calibration, service life and replacement dates in maintenance. Record readings with time and occupancy to reveal trends.
Practical check
- Define sensors, locations and responses for each hazard
- 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 “Monitor CO₂, CO, smoke and radon”?
- 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.
