Dryer vents have a long, unfortunate history of causing tens of thousands of house fires. Dryers depend on a 4-inch diameter, unrestricted, metal vent to exhaust the hot, moist air to the outdoors. Many people regard the vent as a necessary evil and hardly give it another thought. When the dryer takes longer to dry a normal-size load, most people don’t understand why.
If homeowners take quick action and get help to find out the reason behind long dry times, most dryer fires wouldn’t happen. When a dryer suffers from a blocked or restricted vent, lint won’t get exhausted outdoors, but instead, it stays inside the dryer or the vent. Over time, the lint builds up and creates a restriction or blockage that makes its way to the source of the heat.
Imagine for a moment what happens when dryer lint comes into contact with a glowing red heating element or the open flame of a gas burner. Lint inside the dryer ignites quickly and uses air from the vent to help it grow. After ignition, the flame follows the path of the vent and ignites the lint inside the vent.
Most contractors route vents inside walls and ceilings of rooms before they exit the house. A lint fire has the potential to burn through a non-metal vent and catch a house on fire. If that isn’t bad enough, the dryer itself suffers irreparable internal damage caused by the fire.
Dryer lint is very dangerous, and it’s wise to learn how to prevent a dryer fire. To put the danger of lint into perspective, some camping materials suggest using a ball of lint as a firestarter because it ignites with a single match.
Aside from common sense, such as regular vent cleanings and dryer maintenance, replacing your old vent with a rigid or flexible metal vent (rigid preferred) offers the best assurance that if a lint fire starts, there’s a better chance it stays contained inside the vent without spreading to the interior walls. The length of the vent determines its efficiency and can cause restricted airflow if not installed properly.
In every case, replace your vent if it’s plastic or foil. These materials burn and increase the chance of a dryer fire traveling through the vent and igniting interior walls of your house.
Many times, vent installers lack knowledge of proper venting for dryers and, without knowing, they cause another problem that’s more serious than what they’re trying to prevent. According to the International Residential Code (IRC), Section M1502 states metal dryer vent length should be no longer than 25 linear feet. If there’s a bend or 90-degree turn, for each turn or bend, deduct five feet from the 25-foot maximum for the new maximum length.
Regular Maintenance: Schedule regular dryer maintenance checks to ensure that the venting system is clean and clear of obstructions. Professional cleaning at least once a year can significantly reduce the risk of lint buildup and subsequent fires.
Clean the Lint Filter: Always clean the lint filter after every load of laundry. This simple task can prevent lint from accumulating in the dryer and vent system.
Inspect the Vent System: Regularly inspect the vent system for any signs of wear, tear, or blockage. Look for areas where lint might be escaping or collecting.
Use Metal Ducts: As mentioned, replacing plastic or foil ducts with metal ducts can prevent fires from spreading. Metal ducts are more resistant to heat and are less likely to ignite.
Keep the Area Around the Dryer Clean: Ensure that the area around the dryer is free from clutter, flammable materials, and lint buildup. A clean and clear space reduces the risk of accidental fires.
