Texas-based Adventure Playsets has voluntarily recalled about 280,000 wooden play sets in the U.S. and Canada after reports that 16 young children were injured while using them.

The wooden play sets feature swings and slides, with an overhead horizontal ladder that acts both as a monkey bar and swing beam. Most of the reported injuries occurred when the swing came out of the monkey bar/swing beam that had rotted.

The firm received about 1,400 reports of rotting ladders and 16 reports of injuries that resulted in nine emergency-room visits. The injuries included two arm fractures, lacerations, scrapes and bruises to children younger than eight.

No injuries were reported in Canada. About 6,800 sets were sold at Wal-Mart stores across Canada under two brands: Durango and Yukon.

The recall is voluntary and is being done in co-operation with the U.S. Consumer Product Safety Commission and Health Canada. The play sets were made in the U.S. and sold between January 2004 and December 2007.

Consumers should immediately stop using the swing sets and contact Adventure Playsets to receive a replacement kit which includes the horizontal ladder and the vertical end truss support pieces.
