If the house has a prefabricated chimney, the clearance between it and adjacent wood framing should be inspected. The clearance space around the chimney is designed to prevent a problem, however it also creates one because the open space around the chimney generally runs from the boiler/furnace room to the attic. In case of a fire in the boiler/furnace room, the open area around the chimney will act as a flue and draw the flames up into the attic. A fire in the attic can consume the structure in an instant.
This condition can be easily corrected by blocking (fire-stopping) the opening with a noncombustible material such as sheet metal. If the house has a fireplace or a wood-burning stove, check the section of the chimney that is exposed in the attic, looking for soot or creosote buildup around the joints. This is an indication of cracked or open joints through which the exhaust smoke is seeping into the attic. Generally, this problem occurs more often with chimneys than have unlined flues than those with lined flues.
There are many ways to eliminate the risk of a fire in the attic. For instance, a fire in the attic may occur when wiring has become frayed or torn, so checking the electrical wiring in the attic is a very important measure you can take. Then, examining your chimney lining for flaws and ensuring the attic is properly ventilated can also prevent an attic fire.
According to fire safety experts, the installation of a whole house fan or attic fan may pose an increased risk for fire in the attic. Plastic fan parts may pose a fire hazard, so if you do choose to cool your home with an attic fan, make sure it is constructed of quality material such as metal.
If you have a water heater or furnace in your attic, make sure it is properly ventilated. Lack of ventilation may create ideal conditions for an attic fire. Also, examine the water heater flue from time to time, checking for debris or bird nests that may block ventilation.
Very important for preventing a fire in the attic is to keep the area clean, especially if you have a finished attic for storage use or as an additional room. Never leave appliances plugged in when they are not in use, and do not overload your electrical outlets. Check for loose curtains or window furnishings that may block vents. If you use the attic for storage, make sure not to store boxes or other items too close to a vent and, most importantly, do not store combustible items and flammable materials that may ignite.
If your home’s siding has been constructed of flammable materials, there is a significant risk of a fire hazard. When remodeling your home, make sure any modifications are in compliance with safety codes and regulations. Stucco or other options may be safer alternatives to wood siding. Moreover, non-volatile roofing materials would also lower your risk of a fire hazard.
