Abstract
In an apparatus and process for extinguishing the fire of an escaping flow of fossil fuel, such as from an oil or gas well, the preferred apparatus comprises a boom-held, open-ended, split stack equipped with quench fluid outlets on its inside and structure for spreading the stack and closing it around the flame to confine and operate on the flame front. The process involves closing such stack around the flame, preferably with the quench fluid flowing from the opened-up stack as it approaches the fire, then continuing such flow until the fire goes out and the fuel vapors and equipment in the former flame zone are below autoignition temperature.
