Damaged gas pipeline repaired with tape
Let’s face it, you’re a “fixer.” Making broken things right again is your job. So when your backhoe cuts a yellow polyethylene natural gas pipeline, you might be tempted to jump right down in the hole, fold that plastic pipe over, and shut down the leak with duct tape before things can get any worse. DO NOT do it!
Attempting to stop the flow of natural gas in a damaged pipeline can have catastrophic consequences.
Excavator gas explosion
You know that irritating jolt of static electricity that you get when you touch a doorknob after walking across a carpet? The normal flow of natural gas through a pipeline can generate and build up static electricity, too.
If you try to move that damaged natural gas pipeline, it may discharge a spark of static electricity that can easily ignite the leaking gas. Even a static spark from your touch could be enough to trigger an explosion.
So NEVER attempt to stop the flow of gas by bending, pinching, taping or crimping a broken gas pipeline. Leave it alone!
