The Consumer Product Safety Commission issued a voluntary recall for more than 4,500 O-Grill portable gas grills manufactured by Uni-O (Xiamen) Industries Corp. of Xiamen, China. According to the recall, the regulator on the grill can leak gas, which can ignite, posing a fire and burn hazard to consumers. Uni-O has received 10 reports of grills catching fire. No injuries or property damage have been reported. The recall involves Iroda O-Grill models 1000 and 3000 produced before 2010. Some were also sold under the Tailgate Gear brand. Both models are lightweight, portable clamshell-type propane grills with steel bodies, cast iron cooking surfaces, retractable legs and a handle. They can be used with 1-pound propane cylinders or 20-pound propane tanks. The grills come in orange, red, green, blue, silver and black and have the words “O-Grill” stamped on the metal grill cover. Recalled O-Grills do not have ventilation slots in the regulator cover where the propane bottle screws in. Grills with ventilation slots in the regulator cover are not subject to the recall. The grills were sold from November 2008 through December 2010. Consumers should immediately stop using the grills and contact Uni-O to receive a free replacement grill, the recall states.
