From December 24th to 26th, fire deaths go up 50-percent nationwide. The majority of the fire started from dry trees, space heaters and candles, Chief Hood explained.
"A dry tree takes three seconds to ignite, two seconds to spread and 40-seconds to flash over fully involving a room, filling it with deadly heat and toxic smoke."
