"In 2002-2005, U.S. fire departments responded to an estimated
average of 210 home structure fires that began with Christmas trees.
These fires caused an average of 24 civilian deaths, 27 civilian
injuries, and $13.3 million in direct property damage per year. "
"Electrical failures or malfunctions were involved in 48% of the home
Christmas tree fires...Decorative lights with line voltage were
involved in 22% of these incidents"
