Description: The cylinders contain propylene gas and are used for soldering, brazing, cutting and welding. They contain 14.1oz Map-Pro, 14.1oz Propylene or 16oz MAPP (Methyl Acetylene Propadiene Stabilized). The cylinders are approximately 3” in diameter and 11” tall and are either yellow or black in color. They were sold alone and in kits that include a torch and a cylinder. The cylinders and torch kits have a variety of labels and were sold at various plumbing/HVAC distributors, Lowe’s, Home Depot, and Ace Hardware Stores nationwide.
Hazard: The seal on the cylinders can leak after torches or other fuel consuming equipment are disconnected from them, posing a fire hazard.
Remedy: Unused cylinders: If the cylinder has never been connected to a torch or other device, do not use cylinder. 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. 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. In any case, after following these instructions return cylinder to store where it was purchased for exchange or full refund. Also, never leave lit torch and cylinder unattended. Use torch only in a well-ventilated area.
