Protecting the Structure
Check the structure to ensure that the sealing and caulking remains adequate enough to prevent air from leaking in or out.
Examine the structure for voids, cracks, or openings surrounding windows, doors, soffits, pipes, and vents, as these areas can
permit exhaust gas and CO to enter the structure.

The table that follows includes examples of potential entry points for CO gas.

EXPLANATION
Openings that are part of a structure's architecture can permit fresh air and CO into the structure, especially
when open.
An open or improperly unsealed garage door can allow CO to flow into a garage.
Generator exhaust can enter through attic vents and the vents for soffits, crawl spaces, and ridges or roofs.
Basement windows or hatches that permit ventilation to or from the structure's lower level also allow CO gas to
enter the structure.
Air intakes and furnace exhaust pipes are common entry points for CO gas.
Any cracks in a structure's walls, including the foundation and mortar, and any gaps around windows, doors,
and pipes can let CO in.
Sometimes the exhaust vent for the clothes dryer lets CO gas into the structure.
Areas featuring structural corners and heavy vegetation restrict the airflow and collect exhaust gas.
Note: Keep all mechanical and gravity outdoor air intake openings for HVAC supply air systems 10 ft (3,0488
m) horizontally from the generator's enclosure. Refer to section 401 in the ICC Mechanical Code for details on
requirements.
Note: Installing functioning CO alarms indoors is the only way to recognize CO gas. Common smoke alarms
do not detect CO gas and will not alert occupants of its presence.
