Learn how to control the formation of flammable vapor clouds. Then learn what to do when they form. Learn how to prevent ignition and surprisingly, intentional ignition. Learn why!
Interesting. I know of some people living near LPG/NGL pipelines, and the pipeline company is being cagey about how far away to evacuate, & how big a vapor cloud fire can be. They plan for first responders to go door to door to evacuate people, with the likelihood they would be in the vapor cloud. Since this is a mostly suburban area, ignition prevention can be a real issue, I know of some LPG pipeline failures, where the ignition source for the vapor clouds was never found. Also, the intentional ignition of vapor clouds bring to mind the conditions present. A leak in a propane pipeline in Missouri in 1970, in a weather inversion, detonated.
Propane is tricky because it doesn’t just float away. Just the opposite, it finds hidden pockets in the structures and components. Then when the vapor cloud lights off there are several “explosions” as each junction box or crawl space detonates. Check out the video on this channel about PSM Failure at a Gas Processing Plant. It happened on Halloween, so it’s good timing. 🎃
@@EnergyRiskEngineering In 1968, a propane pipeline was leaking, near Yutan Neb. A pipeline repair crew had waited 6 hours for the vapors to disperse, but there was a flash fire when they drove into the area. 5 of them died.
