Zusammenfassung:	The disclosure herein describes a new method of sealing off wells, such as those producing oil and gas in the event of a blowout; the method consists in tapping the well-head with a branch line connected to a supply of liquid carbon dioxide or nitrogen under pressure. The introduction of CO2 or nitrogen into a high-pressure oil rig-pipe has a double purpose; first, if introduced in sufficient quantity, it freezes the pipe and, secondly, in being mixed with the flammable and combustible fluid, it renders the fluid inert, i.e., non-flammable and non-combustible.
