The U.S. Consumer Product Safety Commission announced a recall for Worthington Cylinders'  Map Pro, Propylene, and MAPP gas cylinders. The hazard is that the seal on the cylinders can leak after torches or other fuel consuming equipment are disconnected from them, posing a fire hazard. 

If you are using any of these cylinders for soldering, brazing, cutting and welding, please stop using them immediately. For anyone using MAPP cylinders for your GENTEC hand torches, please replace the MAPP cylinders with Propane cylinders immediately. If you have any questions, please contact us at 909-606-2726 or email us at info@genstartech.com 

Remedy:

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

Partially-used cylinder currently connected to torch or other device: Do not disconnect torch or other device. Take outdoors and ignite the torch and burn off entire contents* of the cylinder. Disconnect the torch from empty cylinder and dispose of empty cylinder per cylinder label instructions or return it to store where it was purchased for exchange or a full refund.

Partially-used cylinder NOT connected to a torch or other device now: 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. If no bubbles develop, do not use cylinder. Return it to the store where it was purchased for exchange or a full refund.
