During the Christmas season many people lose their homes due to live Christmas tree fires. This video sent out by the Fire Prevention Bureau on the code not permitting live Christmas decorations in businesses will make you realize the danger in live Christmas trees. The video shows how quickly a Christmas tree will burn. It is also a good example of how smoke banks down fairly level and why a person should get down as low to the floor as possible if they find themselves in a fire situation. If there is any good air, it's at floor level.
Showing this video to children, old enough to understand, with an explanation of why they should get down and crawl might save their life. I think everyone should email this to family and friends.
Considering an artificial tree is always the best option.
