Allstar Marketing Group is recalling about 265,000 Sharper Image tabletop fire pits because of fire and burn hazards, according to the U.S. Consumer Product Safety Commission. The agency announced the recall on Thursday.

Flammable liquid can catch fire and escape from the products, or cause flame jetting from the fuel containers. This poses a risk of serious injury from burns and fires, the commission said.

Allstar has received four reports of burning fuel escaping from the units during use. These incidents resulted in four injuries, which included third- and fourth-degree burns to multiple parts of the body.

The recall covers Sharper Image-branded Tabletop Fire Pits and Tabletop Infinity Fire Pits. The standard tabletop models have a small concrete body, a removable snuffing lid and an open burn chamber. The infinity models feature a steel base and tempered-glass sides. All of the recalled units have a “77” logo on the front and a lot code sticker on the bottom.

Consumers should stop using the fire pits immediately. To receive a full refund, buyers must register on the recall website, write “RECALLED – DO NOT USE” on the item in permanent marker, and submit three photographs. The commission said consumers should then dispose of any remaining fuel according to local hazardous-waste rules and safely discard the fire pits.

The items were imported by Allstar Marketing Group of Winston-Salem, North Carolina, and manufactured in China. They were sold nationwide at stores including Ace Hardware, Home Depot, Lowe’s, Target, and Walmart, and online at Amazon and HSN.
