Potential CO Entry Points

See Figure 3-1. Generator exhaust can enter a structure
through large openings, such as windows and doors.
However, exhaust and CO can also seep into the struc-
ture through smaller, less obvious openings.

Figure 3-1. Carbon Monoxide—Potential Entry Points
Architectural details which can be (or are) opened to admit fresh air into the structure.
CO can leak into garage if door is open, or does not seal correctly when closed.
Attic vents, ridge vents, crawl space vents, and soffit vents can all admit generator exhaust.
Windows or hatches allowing ventilation to or from lower level of a structure.
Air intake and exhaust pipes for furnace.
Includes (but not limited to) cracks in wall, foundation, mortar, or air gaps around doors, windows, and
pipes. See Protect the Structure.
Exhaust duct for clothes dryer.
Structural features, including but not limited to: corners, alcoves, fences, courtyards, and areas with
heavy vegetation can restrict correct airflow around unit. Exhaust gases can be collected in these
areas.
Do not direct generator discharge into HVAC components, including but not limited to: make up air
systems, AC condensers, and window AC units.
IMPORTANT NOTE: Mechanical and gravity outdoor air intake openings for HVAC supply air
systems shall be located according to Section 401 in the ICC Mechanical Code. See ICC
Mechanical Code for any additional requirements.

Protect the Structure

Verify structure itself is correctly caulked and sealed to
prevent air from leaking in or out. Voids, cracks, or open-
ings around windows, doors, soffits, pipes, and vents can
allow exhaust gas to be drawn into the structure.
Some examples of potential entry points are described
and included in, but not limited to, the accompanying
table.
