WASHINGTON (AP) _ The Consumer Product Safety Commission urged parents Wednesday to install guards on home windows to prevent children from falling. The agency announced standards for window guards, which can be screwed onto the outside of single-family homes and apartment buildings.

``Whether you live in a high rise or a single-family home, a window guard can help prevent a tragedy,'' said Ann Brown, chairman of the CPSC. ``Don't depend on a screen alone to keep children safe.''

The CPSC estimates that about 12 children 10 years and younger die each year, and more than 4,000 are treated in emergency rooms, due to falls from windows. The group cites at least 120 children killed from window-fall deaths since 1990, and most occur to children under 5.

Window guards are priced between $10 and $30. Window stops, which keep the window from opening more than 4 inches, cost about $2.
