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.
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
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.
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.
CSIA recommends that clothes
dryer exhaust duct inspections be performed by CSIA Certified Dryer Exhaust Duct Technicians. 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 that 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.
