A 7-year-old Plano girl died after a large television set fell on her Tuesday night.

Officers responded to the 3500 block of Lakebluff Way around 7 p.m. and found MacKenzie Cole fatally injured. She was pronounced dead at Presbyterian Hospital of Plano. It was unclear how the TV fell on the girl.

Plano police Officer Andrae Smith said no charges were expected to be filed.

The Consumer Product Safety Commission this year listed tipping furniture as one of the top five hidden home hazards. The commission said there were 31 deaths in 2006 related to tipping furniture, including televisions and ranges. The commission estimated that 2,600 children younger than 5 were treated in emergency rooms for tipping-television injuries in 2005.

In the UT Southwestern study, researchers looked at 26 cases handled by the emergency department of Children's Medical Center Dallas between November 2003 and October 2004. The children injured by the falling TVs ranged in age from 1 to 7 years old. None of the injuries were fatal.

The findings included:

•Nine children were hospitalized, including two in the intensive care unit. Fourteen suffered head injuries, and nine injured an arm or leg. More than one-third of the cases were admitted to the hospital for stays ranging from one to four days.

•Televisions with 20- to 30-inch screens made up two-thirds of the cases; TVs 19 inches and smaller made up less than a fifth of the cases; screens between 30 and 40 inches made up the balance.

•Most of the TVs - 85 percent - were placed between 2 feet and 5 feet off the floor.

•Three out of four parents questioned by researchers said the accident occurred because a child was climbing on the set. The rest said the TV was knocked over by another person.

"Parents should place TVs on furniture that is appropriate for the size of the TV," CPSC spokeswoman Arlene Flecha said Thursday.

Parents should also avoid placing items on TVs, such as toys, that would encourage a child to climb on the TV, she said. TV stands with drawers should also be avoided because the drawers could act as steps for a child to climb.
