Last year I wrote a column warning of the dangers of a buildup of clothes dryer lint and the potential for a lint fire inside your home. We always clean the dryer lint screen with every use and never ever leave the clothes dryer running if we are leaving home. Recently, while walking past the laundry area for an evening out, I noticed the distinct odor of smoke and knew right away it was lint. Removing two quarter-inch screws, I found a large buildup of scorched lint under the drum of the clothes dryer. The evening's activities were put on an immediate hold until I was sure there was no lingering or smoldering lint. Incidents like this are preventable. The U.S. Fire Administration estimates that there are 2,900 clothes dryer fires in residential buildings each year, resulting in five deaths and $35 million in property damage. The majority of dryer fires are the result of lint buildup inside the dryer or inside the pipe that vents to the outside. What should you do to prevent a possible dryer lint fire?
