Professional Capping

Short answer: The Reel describes crews putting out gas fires by lowering a heat-resistant steel dome over the flames with heavy machinery, cutting off oxygen so the leak can then be capped or vented.

Firefighting for wells and gas lines also uses water, chemicals and, for large well fires, explosives, before a cap is fitted. The footage shows a dome being lowered onto a fire.

Video transcript: Professional Capping: Crews Lower a Steel Dome Over a Burning Gas Leak

Did you know stopping gas line fires with domes involves placing a large heat resistant steel dome over the burning gas to suffocate the fire by cutting off its oxygen supply. These domes are designed to withstand intense heat and can be lowered onto the fire using cranes or other heavy machinery. Once the dome is in place, it traps the escaping gas, preventing it from fueling the flames while allowing workers to either cap the leak or vent the gas safely. NOW YOU KNOW!
