Kennedy International Inc. announced a voluntary recall of its Folding Step Stools after it was determined the stools can break or collapse unexpectedly when in use, posing a fall hazard to consumers.

In a news release, the company said it is aware of at least 15 reports of incidents involving step stools cracking or breaking, including three reports of injuries to consumers using the stools. Injuries included two reports of back injuries and one report of a fractured leg.

The recall involves 9-inch and 13-inch Kennedy International folding step stools. The step stools are plastic and have a handle for carrying them when they are folded. The style number is 3575 for the 9-inch and 3576 for the 13-inch step stools.

The style number is printed on a sticker on one of the legs of the stool. "Kennedy Home Collection" is also printed on a label on some of the stools. They were sold in the following colors: blue, green, gray, red, purple, pink, orange, turquoise, aqua, white, plum, orchid, emerald, sapphire, sangria, ocean, sage, fuchsia, lime and various color combinations.

About 1.6 million of the recalled stools were sold in the U.S. and 64,000 in Canada at HomeGoods, Marshalls, T.J.Maxx and other retailers nationwide from January 2010 through January 2012 for between $8 and $12.

Consumers were urged to immediately stop using the recalled step stools and to contact Kennedy International at 855-270-8301 to receive a full refund.
