The seal on the cylinders -- used for soldering, brazing, cutting and welding -- can leak after torches or other fuel-consuming equipment are disconnected from them, posing a fire hazard.

The U.S. Consumer Product Safety Commission, Health Canada and Worthington Cylinders Wisconsin (Chilton, Wis.) announced a voluntary recall of Map Pro, Propylene and MAPP gas cylinders used for soldering, brazing, cutting and welding. The seal on the cylinders can leak after torches or other fuel-consuming equipment are disconnected from them, posing a fire hazard. No injuries have been reported at this time.

The cylinders - 29,026,000 units in the United States and 1,371,100 units in Canada - were sold at various plumbing/HVAC distributors, Home Depot, Lowes and Ace Hardware Stores nationwide and in Canada from October 2004 through January 2012 for about $7 to $13 for cylinders and $45 to $75 for torch kits.

They contain 14.1 oz. Map-Pro, 14.1 oz. propylene or 16 oz. methyl acetylene propadiene stabilized. The cylinders are approximately 3 in. in diameter and 11 in. tall, and are either yellow or black in color. They were sold alone and in kits that include a torch and a cylinder.

If the cylinder has never been connected to a torch or other device, do not use the cylinder. Return it to the store where it was purchased for exchange or full refund.

For partially-used cylinders currently connected to a torch or other device, do not disconnect from the torch. Take outdoors, ignite the torch and burn off entire contents of the cylinder. (Never leave a lit torch and cylinder unattended. Use torch only in a well-ventilated area.) Disconnect the torch from the empty cylinder and dispose of empty cylinder per cylinder label instructions or return it to the store where it was purchased for exchange or a full refund.

For partially-used cylinders currently not connected to a torch or other device, take cylinder outdoors. Leak-test top of the cylinder with soapy water. If bubbles develop, attach the torch. Ignite the torch and burn off entire contents of the cylinder. Remove the torch from empty cylinder and dispose of empty cylinder per cylinder label instructions or return it to the store where it was purchased for exchange or a full refund.
