Never?  I suppose it's what you mean by "never":

"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"
