Detection
CO₂ Monitors for Commercial Kitchens
Rising CO₂ in a kitchen or dining room is a direct indicator of inadequate fresh air. Monitoring it protects staff comfort, flags failing ventilation and supports demand-controlled extract.
- Ambient monitors track ventilation performance, not gas leaks
- Typical comfort target below 1000ppm in occupied spaces
- Can drive ventilation boost alongside the gas interlock
Why kitchen CO₂ rises
- Open-flued or unflued gas appliances in an under-ventilated space
- Extract running without adequate make-up air
- Grease-loaded filters reducing extract volume
- Occupancy density in dining areas with recirculated air
Placement and integration
- Monitor at breathing height away from doors and extract inlets
- Separate cellar-type CO₂ safety alarms from ambient comfort monitors
- Link the monitor to ventilation control for demand-based boost
- Log trends to evidence CP42 and ventilation performance
Frequently asked questions
What CO₂ level is too high in a kitchen?
Comfort guidance targets under 1000ppm. Sustained readings above 1500ppm indicate the ventilation is not delivering enough fresh air and should be investigated.
Does a CO₂ monitor replace a CO detector?
No. Carbon monoxide from incomplete combustion requires its own fixed CO detection.
