Buying Guide: CO Alarms for Gas Kitchens
Keep these points in mind before you buy.
CO alarm vs. gas alarm
A CO alarm senses carbon monoxide from burning fuel. An explosive gas alarm senses natural gas or propane leaks. Combo units like Kidde’s do both.
Where to put an alarm near the kitchen
Follow the manual: many makers advise keeping CO alarms away from the stove to cut nuisance alarms, and natural gas and propane sensors have their own height rules.
Kitchen CO sources
Gas stoves, ovens and water heaters burn fuel and can release CO if they are not working properly. CDC advises yearly service by a qualified technician.
Digital display and peak level
CDC suggests considering a detector with a digital readout, which can show the highest CO level in your home in addition to sounding an alarm.
Ventilate while cooking
Use the range hood or open a window when cooking with gas, and never use a gas oven or stove to heat your home.
If the alarm sounds
Get everyone outside to fresh air right away and call 911. Do not go back inside until responders say it is safe.
Kitchen Safety Tips
Cook gas safely:
- Use the range hood.
- Never heat the home with the oven.
- Service gas appliances yearly.
- Test alarms monthly.
