CO Dangers, Dr. D. Penney

Carbon Monoxide Danger in the Garage

Potential for Danger when a Furnace is Located in the Garage:

Make up air / cold air return to furnace is all or partially supplied from the garage.

Auto / lawn mower, or other internal combustion device in or near garage can lead to CO distribution directly into the living space via the heating ducts.

Malfunction in furnace / corroded or improperly installed flue pipes / malfunction of water heater (if also in garage, as shown here) could conduct CO into the living space.

How to avoid CO poisoning:

- Never run car, lawn mower, etc. in/near garage.

- Have 1 or 2 working CO alarms in the house.

- Have heating appliances serviced frequently.

- Change to have all make up air come from the house or the attic.
