Don't Forget
Your Clothes Dryer Vent
The
Chimney Safety Institute of America cautions the public
that there’s a growing fire and carbon monoxide
poisoning danger that could result in unnecessary
deaths, injuries or property damage – the obstruction or
improper venting of clothes dryer exhaust ducts.
To combat dryer fires and carbon monoxide poisoning, the
CSIA recommends that homeowners have clothes dryer
exhaust ducts professionally inspected annually – and
maintained as necessary.
Dryer Locations
CSIA points out that clothes dryers have historically
either been located in basements or on the main floor of
a house and generally within a short distance from an
outside wall. Because of these logistics, the danger of
lint plugging the exhaust duct has been minimal.
But in today’s complex and technologically sophisticated
homes, many clothes dryers could be located in the inner
core of the house in bedrooms, bathrooms, kitchens and
even in hall closets. These new locations mean dryers
need to be vented longer distances and sometimes even
with sharp turns and bends to accommodate the structure
of the home. These complicated systems make exhaust
ducts harder to reach and also create more places where
lint can collect and pile up. Because lint is incredibly
flammable it poses a fire risk.
Natural Gas
The availability of natural gas clothes dryers is
another reason why dryer exhaust duct maintenance is
necessary. If a gas clothes dryer is not properly
vented, it can cause carbon monoxide to be forced back
into the home and that can be deadly.
Obstructions
In addition to lint obstructions or improper venting,
bird’s nests or rodents and bug infestations can also
plug up a vent causing potential fire hazards or carbon
monoxide poisonings. Symptoms of a clogged clothes dryer
exhaust duct include incomplete drying of clothes at
normal temperatures and very hot dryer temperatures.
Recommendations
CSIA recommends that CSIA Certified Dryer Exhaust Duct
Technicians perform clothes dryer exhaust duct
inspections. We have been formally tested in the proper
inspection and maintenance of clothes dryer exhaust
ducts by CSIA. When we inspect a clothes dryer exhaust
duct, we check to make sure there are no obstructions
and if the installation is correct. We also verify that
the correct type of vent is in use. For example, homes
with plastic exhaust ducts are generally upgraded to
metal exhaust ducts.
