WARNING
DUCT LEAKS CAN CREATE AN
UNBALANCED SYSTEM AND
DRAW POLLUTANTS SUCH AS
DIRT, DUST, FUMES AND ODORS
INTO THE HOME CAUSING
PROPERTY DAMAGE. FUMES AND
ODORS FROM TOXIC, VOLATILE
OR FLAMMABLE CHEMICALS, AS
WELL AS AUTOMOBILE EXHAUST
AND CARBON MONOXIDE (CO),
CAN BE DRAWN INTO THE LIVING
SPACE THROUGH LEAKING
DUCTS AND UNBALANCED DUCT
SYSTEMS CAUSING PERSONAL
INJURY OR DEATH (SEE FIGURE
3).
• IF AIR-MOVING EQUIPMENT OR
DUCTWORK IS LOCATED IN
GARAGES OR OFF-GARAGE
STORAGE AREAS - ALL JOINTS,
SEAMS, AND OPENINGS IN THE
EQUIPMENT AND DUCT MUST
BE SEALED TO LIMIT THE
MIGRATION OF TOXIC FUMES
AND ODORS INCLUDING
CARBON MONOXIDE FROM
MIGRATING INTO THE LIVING
SPACE.
• IF AIR-MOVING EQUIPMENT OR
DUCTWORK IS LOCATED IN
SPACES CONTAINING FUEL
BURNING APPLIANCES SUCH
AS WATER HEATERS OR
BOILERS - ALL JOINTS, SEAMS,
AND OPENINGS IN THE
EQUIPMENT AND DUCT MUST
ALSO BE SEALED TO PREVENT
DEPRESSURIZATION OF THE
SPACE AND POSSIBLE
MIGRATION OF COMBUSTION
BYPRODUCTS INCLUDING
CARBON MONOXIDE INTO THE
LIVING SPACE.
