As many of you know I do volunteer fire fighting here in the mountains. This time of the year is the worst for fires. They usually start around the Christmas tree, or a fire left to burn in the fire place with out being secure properly.
Lets talk a minute about the Christmas tree. Most people are careful about their lights as the bulbs get hot. But the tree can usually take a whole bunch of heat. Now you should not leave the lights on over night of course.
The real problem is the chords for the lights. The fires are mostly started by multiple strings of lights on extension chords. Eventually the chords short . The spark from the shorting chord is what sets the fire. So check your chords and make sure you do not over load them. This is the cause of most Christmas tree fires not heat from lights. Have a safe holiday
